Oxalate nephropathy and chronic turmeric supplementation: a case report / Nefropatia por oxalato e suplementação crônica de cúrcuma: relato de caso

ABSTRACT We present a case of a 69-year-old man who presented for routine check-up and was incidentally found to have kidney failure with an initially unrevealing history and bland urinary sediment. He was diagnosed with oxalate nephropathy in the setting of chronic turmeric supplementation and chronic antibiotic therapy with associated diarrhea. Our case provides several key insights into oxalate nephropathy. First, the diagnosis requires a high index of clinical suspicion. It is uncommonly suspected clinically unless there is an obvious clue in the history such as Roux-en-Y gastric bypass or ethylene glycol poisoning. Diagnosis can be confirmed by histopathologic findings and corroborated by serum levels of oxalate and 24-hour urinary excretion. Second, the diagnosis can often be missed by the pathologist because of the characteristics of the crystals unless the renal pathologist has made it a rule to examine routinely all H&E sections under polarized light. This must be done on H&E, as the other stains dissolve the crystals. Third, one oxalate crystal in a routine needle biopsy is considered pathologic and potentially contributing to the AKI or to the CKD in an important way. Fourth, secondary oxalosis can be largely mitigated or prevented in many cases, especially iatrogenic cases. This can come through the surgeon or the gastroenterologist providing proper instructions to patients on an oxalate-restricted diet or other specific dietary measures. Lastly, this case highlights the success that results from cooperation and communication between the pathologist and the treating physician.

RESUMO Relatamos o caso de um homem de 69 anos que se apresentou para exame de rotina e descobriu-se incidentalmente que ele tinha insuficiência renal, com histórico inicialmente não revelador e sedimento urinário brando. Ele foi diagnosticado com nefropatia por oxalato no contexto de suplementação crônica de cúrcuma e antibioticoterapia crônica com diarreia associada. Nosso caso fornece diversas sugestões importantes sobre nefropatia por oxalato. Primeiro, o diagnóstico requer elevado índice de suspeita clínica. A suspeita clínica é incomum, a menos que haja evidência óbvia no histórico, como bypass gástrico em Y de Roux ou envenenamento por etilenoglicol. O diagnóstico pode ser confirmado por achados histopatológicos e corroborado por níveis séricos de oxalato e excreção urinária de 24 horas. Segundo, o diagnóstico pode passar despercebido pelo patologista devido às características dos cristais, a menos que o patologista renal estabeleça como regra examinar rotineiramente todas as seções coradas com H&E sob luz polarizada. Isso deve ser feito com H&E, pois, outras colorações dissolvem os cristais. Em terceiro lugar, um cristal de oxalato em biópsia por agulha de rotina é considerado patológico, contribuindo potencialmente para LRA ou para DRC de maneira significativa. Em quarto lugar, a oxalose secundária pode ser amplamente mitigada ou prevenida em muitos casos, especialmente casos iatrogênicos. Isso pode ser feito pelo cirurgião ou pelo gastroenterologista, fornecendo instruções adequadas aos pacientes sobre uma dieta restrita em oxalato ou outras medidas dietéticas específicas. Por fim, esse caso destaca o sucesso que resulta da cooperação e comunicação entre o patologista e o médico assistente.

Enhanced antitumor effect of curcumin loaded solid lipid nanoparticles in Dalton’s ascites lymphoma mice

Curcumin is widely known for its antibacterial, antioxidant and anti inflammatory effects and has been reported to possess anticancerous activity as well. However, its medical application is limited because of poor bioavailability and rapid metabolism. In this study, we encapsulated curcumin in solid lipid nanoparticles and studied its anticancerous effect in Dalton’s Ascites Lymphoma (DAL) mice model. The physicochemical characteristics of curcumin solid lipid nanoparticles (CUR-SLN) were assessed and the anticancer efficacy was determined by in vivo studies. The curcumin solid lipid nanoparticles were synthesized by solvent emulsification evaporation method with particle size less than 100 nm. Antitumor effect of nanocurcumin (50 mg/kg) and curcumin (100 mg/kg) was evaluated in Dalton’s Ascites Lymphoma bearing mice. Pathological and immunohistochemical parameters were studied. Mean survival time and percentage increase in lifespan were assessed. Nanocurcumin group showed more significant influence in reducing tumor volume and weight, inducing apoptosis, reducing angiogenesis and invasion restoring antioxidant parameters and increased mean survival time. Curcumin and nanocurcumin inhibited the activation of nuclear factor-kappa B (Nf-kB), and thereby proved the pathway by which it induced anti-angiogenic and anti-invasive property.

Antimicrobial activity of essential oils of Curcuma longa and Syzygium aromaticum against multiple drug-resistant pathogenic bacteria

@#The present study was conducted to investigate the antimicrobial potential of essential oils of Curcuma longa and Syzygium aromaticum against multidrug-resistant pathogenic bacteria. Four identified bacterial isolates including Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii were selected and their antibiotic sensitivity was checked by disc diffusion assay. C. longa and S. aromaticum were subjected to steam distillation to obtain their essential oils. The crude essential oils were fractioned by employing column chromatography. Crude essential oils and their fractions were evaluated for their antibacterial activity by agar well diffusion assay and minimum inhibitory concentrations were calculated. All the selected bacterial isolates showed resistance to three or more than three antibiotic groups and were declared as multidrugresistant (MDRs). Crude essential oils of C. longa and S. aromaticum exhibited antimicrobial activity against all selected isolates but S. aromaticum activity was better than the C. longa with a maximum 19.3±1.50 mm zone of inhibition against A. baumannii at 1.04 µL/mL MIC. GC/MS analysis revealed the abundance of components including eugenol, eugenyl acetate, b- caryophyllene, and a- Humulene in both crude oil and fractions of S. aromaticum. While the main components of C. longa essential oil were Ar-tumerone, a–tumerone, b- Tumerone, I-Phellandrene, a-zingibirene, b- sesquiphellandrene, and p- Cymene. This study highlights that plant-based essential oils could be a promising alternative to antibiotics for which pathogens have developed resistance. C. longa and S. aromaticum carry compounds that have antimicrobial potential against multiple drug-resistant bacteria including MRSA. E. coli, K. pneumoniae and A. baumannii.

Material basis and mechanism of Curcuma longa tuberous roots with and without vinegar processing in treating primary dysmenorrhea / 中国中药杂志

Liquid chromatography-mass spectrometry was employed to analyze the chemical components in Curcuma longa tuberous roots(HSYJ), C. longa tuberous roots processed with vinegar(CHSYJ), and rat serum after the administration. The active components of HSYJ and CHSYJ absorbed in serum were identified based on the secondary spectrum of database and literature. The targets of primary dysmenorrhea was screened out from database. The protein-protein interaction network analysis, gene ontology(GO) functional annotation, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed for the common targets shared by the drug active components in serum and primary dysmenorrhea, and the component-target-pathway network was constructed. AutoDock was used to conduct molecular docking between the core components and targets. A total of 44 chemical components were identified from HSYJ and CHSYJ, including 18 absorbed in serum. On the basis of network pharmacology, we identified 8 core components(including procurcumenol, isobutyl p-hydroxybenzoate, ferulic acid, and zedoarondiol) and 10 core targets \[including interleukin-6(IL-6), estrogen receptor 1(ESR1), and prostaglandin-endoperoxide synthase 2(PTGS2)\]. The core targets were mainly distributed in the heart, liver, uterus, and smooth muscle. The molecular docking results showed that the core components were well bound to the core targets, indicating that HSYJ and CHSYJ may exert therapeutic effect on primary dysmenorrhea via estrogen, ovarian steroidogenesis, tumor necrosis factor(TNF), hypoxia-inducible factor-1(HIF-1), IL-17 and other signaling pathways. This study clarifies the HSYJ and CHSYJ components absorbed in serum, as well as the corresponding mechanism, providing a reference for further elucidating the therapeutic material basis and clinical application of HSYJ and CHSYJ.

A new elemane-type sesquiterpenoid glycoside from Curcuma phaeocaulis / 药学学报

To study the chemical constituents and their biological activities in the rhizomes of Curcuma phaeocaulis, silica gel column chromatography, reverse medium pressure liquid chromatography, preparative thin layer chromatography, and semi-preparative high performance liquid chromatography were used for isolation and purification and modern spectroscopic methods were used to determine the structure of the isolated compound. Moreover, the effect of the compound on the proliferation of HUVECs was determined by the MTT assay. A new elemane-type sesquiterpenoid glycoside was isolated from the n-butanol soluble fraction of 95% ethanolic extract of the rhizomes of Curcuma phaeocaulis. Its structure was identified as (1Z)-2-hydroxy-curzerenone 2-O-β-D-glucoside. It showed no inhibitory effect on the proliferation of HUVECs.

Effect of processing with vinegar on efficacy of Curcuma longa in treatment of dysmenorrhea in rats with syndrome of liver depression and Qi stagnation / 中国中药杂志

This study compared the effects of Curcuma longa before and after processing with vinegar on the rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation to reveal the mechanism of vinegar processing in improving the role of C. longa in soothing liver and relieving pain. The rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation was established according to the Preparation of the Animal Model of Dysmenorrhea(Draft) and the chronic unpredictable stress me-thod. The changes in the body weight, organ indexes, writhing latency, writhing score, and serum levels of six liver function indicators, sex hormones, pain factors, and blood rheological indicators were measured to evaluate the efficacy of C. longa processed with vinegar or not in treating dysmenorrhea in the rats with syndrome of liver depression and qi stagnation. Compared with the model group, the C. longa group(processed with vinegar or not) showed slow weight loss, increase in writhing latency, and decrease in writhing response(P<0.05). The inhibition rates on writhing in raw C. longa, vinegar-processed C. longa, and positive groups were 33.780%, 64.611%, and 62.466%, respectively. The significantly higher inhibition rate of the vinegar processing group indicated that vinegar-processed C. longa demonstrated more significant therapeutic effect. The vinegar-processed C. longa group showed lower levels of alanine aminotransferase(ALT), alkaline phosphatase(ALP), aspartate aminotransferase(AST), direct bilirubin(DBIL), and total bilirubin(TBIL) and higher level of albumin(ALB)(P<0.05), which indicated that vinegar processing enhanced the therapeutic effect of C. longa on liver injury. The serum levels of estradiol(E_2) and oxytocin(OT) were lower in the vinegar-processed C. longa group(P<0.05), indicating that the vinegar-processed C. longa could regulate the sex hormone levels, reduce the activity of uterine smooth muscle and contraction of uterus, and alleviate the symptoms of dysmenorrhea in rats. Moreover, the vinegar-processed C. longa group showed lower interleukin-6(IL-6) and arginine vasopressin(AVP) levels and higher beta-endorphin(β-EP) level(P<0.05), which indicated that vinegar-processed C. longa regulated the levels of pain factors to exert the pain-relieving effect. Drug intervention decreased the whole blood viscosity low-cut, medium-cut and high-cut values, plasma viscosity, whole blood reduction viscosity low-cut and high-cut values, erythrocyte cumulative pressure, and equation K value of erythrocyte sedimentation rate(P<0.05), and the vinegar-processed C. longa group outperformed other groups. This result indicated that vinegar processing enhanced the function of C. longa in improving the local blood rheology. C. longa processed with vinegar can enter the liver to relieve the da-mage to the heart, liver, kidney, and uterus, repair the liver function, and recover the sex hormone levels and immune function by regulating the levels of sex hormones and pain factors and improving the blood rheology. It activates the pain-relieving mechanism to relieve the pain, protect the liver, and fight inflammation, which is consistent with the theory that vinegar processing facilitates C. longa entering the liver to sooth liver and relieve pain.

A comparative study to evaluate the effects of antibiotics, plant extracts and fluoride-based toothpaste on the oral pathogens isolated from patients with gum diseases in Pakistan

Abstract Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.

Resumo As doenças bucais causadas por vários microrganismos são comuns em todo o mundo. A pesquisa científica agora tem se concentrado em novos medicamentos para superar a resistência bacteriana e os efeitos colaterais dos antibióticos; portanto, o presente estudo foi desenhado para avaliar a eficácia de certos antibióticos, pasta de dente e extratos de plantas medicinais (Ajuga bracteosa e Curcuma longa) contra os patógenos bacterianos isolados da cavidade oral humana. No total, 130 amostras foram coletadas do Khyber Teaching Hospital Peshawar, Paquistão, entre essas, 27 espécies foram isoladas e oito espécies bacterianas foram identificadas a partir das amostras. Entre todas as espécies bacterianas, Staphylococcus aureus (29.62%) e Proteus mirabilis (22.2%) foram os patógenos orais mais prevalentes. Em comparação, os micróbios menos difundidos foram Proteus vulgaris, Shigella sonnei, Escherichia coli e Aeromonas hydrophila. O estudo também sugeriu que os problemas dentários eram mais prevalentes em homens (41-50 anos de idade) do que em mulheres. Entre os oito antibióticos usados no estudo, os resultados mais promissores foram mostrados pelo Foxicillin contra A. hydrophila. A pesquisa de TP1 revelou que ele mostrou atividade antagonista mais potente contra Proteus vulgaris em comparação a TP2 e TP3, o que pode ser devido ao alto teor de flúor. A Curcuma longa apresentou atividade mais significativa em relação aos extratos de Ajuga bracteosa (caule, folhas e raiz). Os dados obtidos neste estudo revelaram que os antibióticos foram mais eficazes para os patógenos bacterianos orais do que os dentifrícios e os extratos vegetais que apresentaram atividade moderada e baixa, respectivamente. Portanto, sugere-se que os compostos ativos em plantas medicinais individuais como Curcuma longa e Ajuga bracteosa possam substituir os antibióticos quando usados na rotina diária como limpadores de dentes ou enxaguatórios bucais.

Produtos fitoterápicos manipulados em um laboratório de manipulação no Estado do Paraná / Phytotherapeutic products handled in a handling laboratory in the State of Paraná / Productos fitoterapéuticos manipulados en un laboratorio de manipulación en el Estado de Paraná

As plantas medicinais foram os primeiros recursos terapêuticos obtidos pelos povos e há registros do seu uso em todos os momentos da História, por grande parte das civilizações. No Brasil, o uso das plantas medicinais é resultado dos conhecimentos de três populações: indígena, europeia e africana. O presente trabalho tem como objetivo caracterizar a manipulação mensal de um laboratório de fitoterápicos na cidade de Francisco Beltrão, Paraná. Os dados que foram coletados para a presente pesquisa são: número de cápsulas manipuladas mensalmente para cada um dos fitoterápicos, os quais serão obtidos a partir dos relatórios de manipulação de fitoterápicos mensais no ano de 2021 e individuais de cada unidade de saúde, fornecidos pela Secretaria de Saúde. Não havendo acesso a informações de pacientes e tampouco contato com eles. As informações dos relatórios foram tabuladas em planilha a fim de se estabelecer os três principais fitoterápicos manipulados no período preestabelecido. Trata-se de um estudo de campo, exploratório, documental e retrospectivo. Observamos que a média de manipulação foi de 34.029 cápsulas por mês, os fitoterápicos mais manipulados no ano de 2021, foram: Passiflora incarnata (maracujá), Aesculus hippocastanum (castanha da índia) e Curcuma longa. Também foi possível notar que houve um aumento gradual de dispensações após a capacitação dos profissionais, ocorrida entre junho e setembro. Além disso, verificamos que há uma grande diferença na quantidade dispensada por cada farmácia municipal, possivelmente devido ao nível de conhecimento dos profissionais de saúde e se preferem ou não prescrever aos pacientes.

Medicinal plants were the first therapeutic resources obtained by people and there are records of their use at all times of history, by a large part of civilizations. In Brazil, the use of medicinal plants is a result of the knowledge of three populations: indigenous, European and African. The present work aims to characterize the monthly handling of a plant medicine laboratory in the city of Francisco Beltrão, Paraná. The data that were collected for this research are: number of capsules handled monthly for each one of the phytotherapics, which will be obtained from the reports of handling of monthly phytotherapics in the year 2021 and individual of each health unit, provided by the Secretariat of Health. There is no access to patient information and no contact with them. The information in the reports was tabulated into a spreadsheet in order to establish the three main phytotherapics handled in the pre-established period. This is an exploratory, documentary and retrospective field study. We observed that the average handling was 34,029 capsules per month, the most manipulated phytotherapics in the year 2021, were: Passiflora incarnata (passion fruit), Aesculus hippocastanum (chestnut from India) and Curcuma longa. It was also possible to note that there was a gradual increase in dispensations after the training of professionals, which took place between June and September. In addition, we note that there is a big difference in the amount dispensed by each municipal pharmacy, possibly due to the level of knowledge of health professionals and whether or not they prefer to prescribe to patients.

Antibacterial efficacy of manuka honey, ocimum sanctum, curcuma longa and 0.2% chlorhexidine mouthwash on the level of streptococcus mutans and lactobacillus acidophilus - A randomized controlled trial

Objective: To assess the effects of Manuka honey, Ocimum sanctum, Curcuma longa, and 0.2% chlorhexidine mouthwash on Streptococcus mutans and Lactobacillus acidophilus levels. Material and Methods: A randomized controlled trial will be conducted on dental students of Teerthanker Mahaveer Dental College and Research Centre, Moradabad. The study participants will be divided into four groups. Each group will have a total of 20 individuals. By using a lottery system, Group A (Manuka honey mouthrinse), Group B (Ocimum sanctum mouthrinse), Group C (Curcuma longa mouthrinse), and Group D (0.2% chlorhexidine mouthrinse) will be chosen. To match the circadian cycle, saliva will be collected at baseline and again after 2 weeks between 10 and 10.30 a.m. The sterile container will subsequently be delivered to the microbiological laboratory and processed as soon as possible to measure Streptococcus mutans and Lactobacillus acidophilus count. For 2 weeks, participants were told to use 10 mL of mouthrinse twice daily. Results: The mean oral hygiene index?simplified (OHI?S) score of all the four groups showed reduction in their scores from baseline to after the study period. For both S. mutans and L. acidophilus, there was a substantial Percentage Reduction (PR) between the prerinse and postrinse samples in all four groups. Discussion: Because quantitative actions play a crucial part in the caries disease process, the changes in microbial activity before and after administration of experimental mouthwashes were examined. Conclusion: Essential oil aqueous extracts were as efficient antibacterial mouthwashes as chlorhexidine and iodine mouthwashes

Evaluation of In vitro Activity of Antimicrobial Potential and Phytochemical Screening of Methanol Extract of Curcuma longa Linn against Some Clinical Isolates

Since ancient times, plants have been used as a source of medicinal compounds. This study was carried out to assess the antimicrobial potential of the methanol extract of Curcuma longa rhizome against some clinical isolates. A total of seven clinical isolates including Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Candida albicans, Aspergillus flavus, and Fusarium species were used. Different concentrations of the extracts were made. Agar well diffusion methods were used for bacterial and Candida albicans while agar dilution technique was used for the mold strains. Ciprofloxacin and Fluconazole were used as a standard positive control against the bacteria and fungi respectively. Dimethyl sulfoxide (DMSO) was used as a negative control. The result showed that methanol extract of Curcuma longa rhizome inhibited the growth of all tested organisms. The zone of inhibition of K. pneumoniae ranged from 9.33-13.33mm, S. aureus, 6.33-12.67mm, E. coli, 8- 11.67mm, P. aeruginosa, 7.67-10mm, and Candida albicans 8.33-13mm while the control drug Ciprofloxacin ranged from 25.33-41.33mm and fluconazole was 20mm. The percentage inhibition of diameter of growth of Fusarium spp ranged from 74.61-100% and that of A. flavus ranged from 32.44-100%. The positive control drug (Fluconazole) and 250mg/ml of the extract showed complete inhibition of the test organisms. Qualitative phytochemical studies of the extract of Curcuma longa in different solvents (N-hexane, water, methanol, and acetone) showed the presence of alkaloids, phenols, saponins, steroids, tannins, glycosides, and flavonoids. This result is indicative of its broad-spectrum antimicrobial potential and could be employed in the management and treatment of infections. This study corroborates the plant's historic use and lays the groundwork for potential therapeutic development.

Effect of dietary plants on the production of immunoglobulins A in healthy Wistar rats / Efeito de plantas dietéticas na produção de imunoglobulinas A em ratos Wistar saudáveis

Introduction: some plants such as turmeric, cinnamon, and okra are known to have therapeutic functions such as antioxidant and anti-inflammatory activity. Furthermore, an immunomodulatory role has been observed in the production of antibodies, in particular immunoglobulin A (IgA), which mediates a variety of protective functions for the organism. Objective: the aim of the present study was to investigate the effect of dietary plants on the production of IgA in healthy Wistar rats. Methods: thus, 48 male Wistar rats of 90 days of age were allocated to four groups. The animals were treated for 14 days with dried turmeric, cinnamon, or okra (50, 50, 12.5 mg/day, respectively) in phosphate buffered saline, or with only phosphate buffered saline by gavage. The animals received water and feed ad libitum. Body mass and relative weight ofperitoneal fat, adrenal gland, kidney, spleen, liver and thymus, biochemical parameters, and IgA levels were analyzed. Results: no significant changes were observed in the body mass, relative weight of organs and tissues, and biochemical parameters. An increase in serum IgA levels was observed in animals treated with turmeric or cinnamon. Conclusion: we conclude that the treatment with turmeric and cinnamon increased IgA production. Therefore, our study supports the idea that dietary supplementation with these plants may improve humoral immunity.

Influence of different preparation techniques on the composition and antioxidant action of curcumin and curcuminoids / Influencia de diferentes técnicas de preparación en la composición y acción antioxidante de la curcumina y los curcuminoides

Epidemiological evidence indicates that plant antioxidants activity can treat or help to prevent the development of various diseases. One species with great potential as an antioxidant is Curcuma longa. However, different extraction techniquescan influence isolated chemical compounds. This study investigated chemical composition and antioxidant activity of two rhizome extracts of C. longa: hydroethanolic, obtained by exhaustion (HECLex); and dried by a spray dryer (HECLsd). The phytochemical composition was evaluated by GC/MS. Antioxidant activity was evaluated using DPPH and FRAP assays. Total phenolic compounds and soil analyses were performed. The main components of HECLex were ar-turmerone, γ-curcumene, α-turmerone, and ß-sesquiphellandrene. The main components of HECLsd were 9,12,15-octadecatrienoic acid, 2, 3-bis([trimethylsilyl]oxy) propyl ester, verrucarol, and 1-monolinoleoylglycerol trimethylsilyl ether. HECLsd had significantly higher levels of phenolic compounds and higher antioxidant capacity compared with HECLex. In conclusion, processes of the preparation of C. longarhizomes alter the chemical components and consequently their biological activity.

Research progress of Curcuma kwangsiensis root tubers and analysis of liver protection and anti-tumor mechanisms based on Q-markers / 中国中药杂志

Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.
