Potential benefits of Rehmanniae Radix after ancient rice-steaming process in promotion of antioxidant activity in rats' health.

Rice steam processed product of Rehmanniae Radix (RSRR), one of the processed products of Rehmanniae Radix (RR), is popular as an herbal medicine and food. However, the health-promoting effects and mechanisms of RSRR are still unclear. In this study, 10-week-old Sprague-Dawley female rats were treated with different processed products of RR. No organ coefficient differences were observed between RSRR and the control group, indicating that RSRR did not cause damage to the rats. Compared with other RR products, superoxide dismutase, glutathione, and catalase levels were significantly higher and malondialdehyde levels were significantly lower in the RSRR group, indicating that RSRR exerted a better antioxidant effect. Gene expression analysis showed that hemoglobin genes (Hba-a1, Hba-a2, Hbb-bs, Hbb, Hbq1b, Hbb-b1, and LOC103694857) may be potential biomarkers to evaluate the antioxidant effect of RSRR. Antioxidation-related signaling pathways in GO annotation, including cellular oxidant detoxification, hydrogen peroxide metabolic process, hemoglobin complex, and oxygen binding signaling pathways were significantly enriched, indicating these pathways may represent the antioxidant mechanism of RSRR. To explore the main active compounds primarily responsible for the antioxidant activity of RSRR, UPLC-Q-TOF-MS was used and six components (catalpol, rehmannioside A, rehmannioside D, melittoside, ajugol, and verbascoside) were identified in rat serum. Catalpol and rehmannioside A were predicted to be the major active components by network pharmacology. These results suggested that RSRR exhibits antioxidant activity and has health-promoting properties. This study provides a scientific basis for the antioxidant mechanism and clinical use of RSRR.

Acid ground nano-realgar processed product inhibits breast cancer by inducing mitophagy via the p53/BNIP3/NIX pathway.

Breast cancer is a highly prevalent malignancy with the first morbidity and the primary reason for female cancer-related deaths worldwide. Acid ground nano-realgar processed product (NRPP) could inhibit breast cancer cell proliferation and induce autophagy in our previous research; however, the underlying mechanisms are still unclear. Therefore, this research aimed to verify whether NRPP induces breast cancer mitophagy and explore the mitophagy-mediated mechanism. Primarily, rhodamine-123 assay and transmission electron microscopy were applied to detect mitochondrial membrane potential (MMP) and ultrastructural changes in the MDA-MB-435S cells, respectively. Mito-Tracker Green/Lyso-Tracker Red staining, western blot, immunofluorescence and RT-PCR were used to explore molecular mechanisms of NRPP-induced mitophagy in vitro. MDA-MB-435S breast cancer xenograft models were established to assess the activity and mechanisms of NRPP in vivo. Our results showed that NRPP decreased MMP and increased autophagosome numbers in MDA-MB-435S cells and activated mitophagy. Furthermore, mitophagy was consolidated because mitochondria and lysosomes colocalized phenomenology were observed, and the expression of LC3II/I and COXIV was upregulated. Additionally, we found the p53/BNIP3/NIX pathway was activated. Finally, NRPP inhibited tumour growth and downregulated the levels of TNF-α, IL-1ß and IL-6. Necrosis, damaged mitochondria and autophagosomes were observed in xenograft tumour cells, and proteins and mRNA levels of LC3, p53, BNIP3 and NIX were increased. Overall, NRPP inhibited MDA-MB-435S cell proliferation and tumour growth by inducing mitophagy via the p53/BNIP3/NIX pathway. Thus, NRPP is a promising candidate for breast cancer treatment.

Monitoring arsenic species concentration in rice-based processed products distributed in South Korean markets and related risk assessment.

Rice is an important grain as a major source of carbohydrates in Asia but contains more arsenic (As) than other grains. A total of 239 rice-based processed foods (rice, n = 30; rice cake, n = 30; porridge, n = 39; noodles, n = 33; bread, n = 20; snack, n = 59; powder, n = 28) were purchased in 2019 from domestic markets to measure total As (tAs) and As species. The average tAs and inorganic As (iAs) in each sample group ranged from 20 to 180 µg/kg (porridge for baby to noodle) and 4.4-85 µg/kg (porridge for baby to powder), respectively. The correlation between the iAs and tAs was affected by the variety of ingredients, such as the presence of seaweed (tAs) and the milling type of rice (iAs). Although rice cakes and baby rice-based powders are a source of concern for both adults and children, respectively, risk assessments indicate that most rice-based foods are generally safe to consume in South Korea.

Exploring genetic variability, heritability, and trait correlations in gari and eba quality from diverse cassava varieties in Nigeria.

BACKGROUND: Gari (especially in Nigeria) is an important West African food product made from cassava. It is an affordable, precooked, dry, easy to prepare and store food product. Eba is a stiff dough produced by reconstituting gari in hot water. Gari and eba quality is an important driver of varietal acceptance by farmers, processors, and consumers. RESULTS: This study characterized the genetic variability, heritability, and correlations among quality-related traits of fresh roots, gari, and eba. Thirty-three diverse genotypes, including landraces and released and advanced breeding genotypes, were used in this study. In total, 40 traits categorized into fresh root quality, colour, functional, and texture properties trait groups were assessed. We observed broad phenotypic variability among the genotypes used in this study. Dry matter content had a positive (P < 0.05) correlation with gari%, bulk density and a negative correlation with eba hardness and gumminess. Broad-sense heritability across all environments varied considerably among the different trait groups: 62% to 79% for fresh root quality, 0% to 96% for colour, 0% to 79% for functional and 0% to 57% for texture properties. CONCLUSIONS: The stable broad-sense heritability found for gari%, gari and eba colour, bulk density, swelling index, and hardness measured using instrumental texture profile analysis coupled with sufficient variability in the population indicate good potential for genetic improvement of these traits through recurrent selection. Also, it is possible to genetically improve gari%, bulk density, and swelling power by simultaneously improving the dry matter content of fresh roots. © 2023 The Authors.

[Slicing specifications in general rule of processing in Chinese Pharmacopoeia from slicing development of Chinese materia medica processed product and thinking and suggestion on slicing techniques].

Slicing is critical in the processing of Chinese materia medica(CMM) processed product and the specification(thickness) is closely related to the quality of the decoction. On the basis of clarifying the concept and evolution of slicing of CMM processed product by reviewing the Chinese herbal classics of the past dynasties and general rules of local processing standards, this study discussed the development history of slicing specifications in general rules of Chinese Pharmacopoeia(2020 edition), analyzed the current situation and key problems, and proposed the thinking and suggestion on promoting the sound development of slicing of CMM processed product. Since 2000, the slicing thickness of CMM processed product in the general rules of local CMM processed product processing specifications newly revised and issued by 27 provinces, autonomous regions, and municipalities has been consistent with that in the general rules of the Chinese Pharmacopoeia(2020 edition). The standard that the thickness of extremely thin pieces is less than 0.5 mm is rarely retained, and the pieces in 0.5-1 mm thickness have not been found on the market, which is consistent with the provisions of the general rules of the Chinese Pharmacopoeia. This study can provide a historical and modern basis for the rationality of slicing of CMM processed product.

Pharmacokinetic/Pharmacodynamic Study of Salt-Processed product of Cuscutae Semen with Hepatoprotective Effects.

BACKGROUND: Salt-processed product of cuscutae semen (SCS), which is documented in Chinese pharmacopoeia (2020 edition), is one of the processed products of cuscustae semen. SCS possesses hepatoprotective effects. However, Pharmacokinetic / Pharmacodynamic (PK-PD) study of SCS with intervening acute liver injury (ALI) has not been reported yet. Effective constituents are still not well addressed. OBJECTIVE: This study was performed to study PK-PD properties with the purpose of linking SCS hepatoprotective effects to key therapeutic outlines to guide therapeutic use in clinical settings. METHODS: Rats were orally administered SCS after the acute liver injury model was established. Plasma biochemical analysis, antioxidative analysis, and liver histopathology were measured to evaluate the hepatoprotective effects of SCS. Blood samples were collected at different time points (0 h, 0.083 h, 0.25 h, 0.5 h, 1 h, 1.5 h, 2 h, 3 h, 4 h, 8 h, 12 h, 24 h) for PK/PD study after SCS administration. Contents of chlorogenic acid, hyperoside and astragalin were estimated by UHPLC-ESI-MS. The relationship between concentrations of chlorogenic acid, hyperoside, and astragalin and hepatoprotective effects was assessed by PK-PD modeling. RESULTS: The results showed that SCS ameliorated liver repair and decreased the serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST) markedly. Hepatic oxidative stress was inhibited by SCS, as evidenced by a decrease in malondialdehyde (MDA) and an increase in glutathione (GSH) and superoxide dismutase (SOD) in the liver. PK-PD correlation analysis indicated that concentrations of chlorogenic acid, hyperoside, and astragalin were negatively correlated with level of AST and ALT. CONCLUSION: The encouraging finding indicates that SCS has beneficial effects on CCl4-induced liver damage. Chlorogenic acid, hyperoside, and astragalin are three effective constituents to exert hepatoprotective effects while astragalin may have maximum pharmacological activity. PK-PD study reveals the positive relationship between drug concentration and action intensity of SCS against liver injury. This research provides a robust foundation for future studies.

Water-Energy-Food Nexus and Life Cycle Thinking: A New Approach to Environmental and Nutritional Assessment of Potato Chips.

The water-energy-food (WEF) nexus has become a key concept to promote the cross-sectoral coordination toward sustainable development. In particular, understanding the interdependences of these pillars, as well as addressing a life cycle perspective, is essential when evaluating food production systems. This study explores the environmental impacts and nutritional quality of potato chips, addressing life cycle thinking and a WEF nexus approach. For this purpose, the combined application of life cycle assessment (LCA) and the Nutrient-Rich Food 9.3 (NRF9.3) index was considered to identify the main environmental hotspots and advanced opportunities. The results indicated a major contribution of the cultivation stage on water use, whereas the processing accounted for most of the impacts in energy-related indicators and eutrophication potentials. Improvement opportunities reside in the joint application of drip irrigation, allowing to achieve important water savings, as well as the use of natural gas or pellets instead of diesel, which constitute cleaner energy sources. On the other hand, a poor nutritional density of potato chips became evident from the quantification of the NRF9.3, which can be significantly improved if potatoes undergo a roasted process instead of frying.

Quantification and health risk assessment of lead and cadmium in wheat, rice, and their processed products from Peru.

In Peru, rice grains, wheat, and their processed products are accessible due to their low cost; however, their sale does not have quality certification, so their safety is not guaranteed. This study quantified lead (Pb) and cadmium (Cd) by voltammetry in 16 samples of grains and processed products from four markets in Arequipa (Altiplano, Andrés Avelino Cáceres, Los Incas, and San Camilo) and evaluated their potential health risk. The maximum concentrations of Pb in rice, wheat, and their processed products were 4.821 mg/kg, 7.962 mg/kg, 4.717 mg/kg, and 6.440 mg/kg, respectively; only seven samples showed Cd. All samples exceeded the maximum level (ML) for Pb, and four samples exceeded the ML for Cd established by the Codex Alimentarius (0.200 mg/kg); the rice product had the highest concentration of Pb and Cd. In relation to the estimation of potential health risk, the estimated daily intake (EDI), target hazard quotient (THQ), and target cancer risk (TR), showed that the consumption of all processed rice and wheat products (except Andrés Avelino Cáceres rice and San Camilo wheat) represent a health threat associated with an increased probability of cancer development.

Mechanism exploration of ancient pharmaceutic processing (Paozhi) improving the gastroprotective efficacy of Aucklandiae Radix.

ETHNOPHARMACOLOGICAL RELEVANCE: Processing, also called Paozhi in Chinese, is an ancient Chinese pharmaceutic processing technique developed along with the Chinese herbal medicines (CHMs). The understanding of the mechanism of Paozhi has been investigated for several decades. Aucklandiae Radix (CAR) and its roasted processed products are all used in indigestion as a kind of CHMs. Processed Aucklandiae Radix (PAR) had a stronger effect to protect gastric mucosa than CAR, while the main compounds in CAR were reduced sharply after being processed. The underlying mechanism of this phenomenon is still unclear. AIM OF THE STUDY: This study was aimed to evaluate whether PAR have a stronger gastroprotective effect than CAR and the underlying mechanisms of such circumstance. MATERIALS AND METHODS: Ultra-fast liquid chromatography coupled with quadrupole time of flight mass spectrometry (UFLC-QTOF-MS/MS) coupled with multivariate statistical analyses was employed to explore chemical compounds which had a relatively stable content in PAR. Based on the compounds selected as the research object, network pharmacology was applied to visualize the relationships between the selected components and the gastroprotective-related targets from disease database, at the same time the possible intervention path of CAR/PAR which might be responsible for the effect of CAR/PAR on gastritis-induced rats was also built. Then, the key proteins were detected by western blotting to verify and compare the pharmacological effects of CAR/PAR. RESULTS: Through UFLC-QTOF-MS/MS and orthogonal partial least squares discriminant analysis (OPLS-DA), sixteen compounds stable in PAR were discovered, of which saussureamine C and saussureamine B were estimated as the core compounds to exert gastroprotective in PAR predicted by network pharmacology analysis. Under the guide of KEGG pathway enrichment analysis, PI3K/AKT, p38 MAPK (Mitogen-activated protein kinase) and nuclear factor-kappa B (NF-κB) signaling pathways were forecasted as the possible healing mechanisms of CAR/PAR, and that result was verified by the experiments in vivo. PAR performed a stronger ability to reduce the level of p38 MAPK and NF-κB p65 than CAR, which may partially explain the different ability of CAR/PAR against gastric mucosa damage. CONCLUSION: This study clarified that although Paozhi entailed a sharp decrease on the main compounds of CAR, there were some compounds which were not sensitive to high temperature and preserved in PAR and had a relative higher content in PAR than in CAR. PAR has stronger influence on MAPKs/NF-κB signaling pathway than CAR, which may reveal that the stronger gastroprotective effect of PAR perhaps rely on the constitutions with a higher relative abundance after Paozhi. The present research combined UFLC-QTOF-MS/MS and network pharmacology deeply investigated the impact of the roasted processing on the chemical constitutions and gastroprotective effect of CAR and offered reference for the clinical application of CAR/PAR.

Objective To investigate the difference of hypoglycemic and hypolipidemic effects of Coptis deltoidea (Coptis chinensis) and its processed products on T2DM rats. Methods Type 2 diabetes mellitus induced by high sugar, high fat diet and low dose of streptozotocin. C. deltoidea were processed with yellow wine, ginger, and evodia rutaecarpa, respectively. The effects of C. deltoidea on fasting blood glucose (FBG), fasting insulin (FINS), glycosylated serum protein (GSP), pancreatic pathology, serum triglyceride (TG), total cholesterol (TC) and lipoprotein (HDL-C or LDL-C) and key protein and gene expression of SCAP\SREBP-1c pathway in liver of model rats were investigated. Result C. deltoidea and its processed products reduced the FBG and GSP in T2DM rats. The wine products significantly reduced FBG and GSP in model rats (P < 0.01). The hypoglycemic range was better than raw and ginger products. At hypolipidemic aspect, C. deltoidea and its processed products decreased the content of TG, TC, and LDL-C (P < 0.05, 0.01), increased the content of HDL-C in serum (P < 0.05, 0.01), and down-regulated the protein and gene expression of SCAP/SREBP-1c in liver, the insulin target organ. However, wine and evodia products were better than crude drug or ginger products. Conclusion C. deltoidea processed by yellow wine, ginger and evodia rutaecarpa is traditional method to improve the disadvantages of C. deltoidea with bitter cold nature and not easy to take for a long time. However, different processing methods have different effects. Clinical medication should be combied withTCM syndrome differentiation and simple hypoglycemic effect of wine product is appropriate; while wine and evodia products were better in hypoglycemic and lipid regulation aspects.

OBJECTIVE： To provide reference for standardizing rational use of set prescription preparation containing Coptis chinensis and its processed product. METHODS： By retrieving 2015 edition of Chinese Pharmacopeia·Guidelines for Clinical Drug Use（volume of TCM set prescription）， the inclusion of set prescription preparation containing C. chinensis and its processed product were summarized and analyzed. RESULTS&CONCLUSIONS： There were 127 set prescription preparations containing C. chinensis and its processed product included in 2015 edition of Chinese Pharmacopeia·Guidelines for Clinical Drug Use（volume of TCM set prescription）， among which， there were 83， 5， 2， 8， 4， 11， 6， 5 and 3 set prescription preparations for internal medicine， surgery， gynecology， pediatrics， dermatology， ophthalmology， pharyngology， stomatology， orthopedics and traumatology， respectively. There were 120 set prescription preparations containing C. chinensis（94.49％）， 2， 4 and 1 set prescription preparations containing prepared C. chinensis with vino， prepared C. chinensis with ginger and prepared C. chinensis with Euodia rutaecarpa， respectively. There were 39， 59 and 29 kinds of set prescription preparations with C. chinensis as main symptoms medicine， assists medicine and complication medicine， which were mainly for clearing heat， drying dampness， purging fire and detoxifying（104 kinds， 81.89％）. Main types included Shexiang niuhuang pills， Gegen cenlian tablets， Kaiwei jianpi pills， etc. By comparing the efficacy of C. chinensis and its processed product， it was found that the names of processed products were not standardized， the labeling of C. chinensis and its processed products were not uniform and the application was not standardized； the related contents still needed to be further improved. It is necessary to strengthen the research on the pharmacodynamic basis and processing standard of C. chinensis and carry out the investigation and correction of relevant publications in order to help improve the rational drug use level of set prescription preparations containing C. chinensis and its processed products.

Factors associated with the intake of traditional foods in the Eeyou Istchee (Cree) of northern Quebec include age, speaking the Cree language and food sovereignty indicators.

The Eeyouch are a First Nations (Cree) population that live above 49.6°N latitude in Eeyou Istchee in northern Quebec. Eeyouch rely on traditional foods (TF) hunted, fished or gathered from the land. The overarching aim of this study was to achieve an understanding of the factors associated with TF intake among Eeyouch. Data were from 465 women and 330 men who participated in the Nituuchischaayihtitaau Aschii Multi-Community Environment-and-Health (E&H) study. The relationship between TF consumption and dietary, health, sociodemographic and food sovereignty (i.e. being a hunter or receiving Income Security to hunt, trap or fish) variables was examined using linear and logistic regression. Analyses were stratified by sex because of the male/female discrepancy in being a hunter. Among respondents, almost all (99.7%) consumed TF, 51% were hunters and 10% received Income Security. Higher intake of TF was associated with lower consumption of less nutritious ultra-processed products (UPP). In women, TF intake increased with age, hunting and receiving Income Security, but decreased with high school education. In men, TF intake increased with age and speaking only Cree at home. The findings suggest that increased food sovereignty would result in improved diet quality among Eeyouch through increased TF intake and decreased UPP intake.

[Pharmacological effects and clinical applications of Zingiber officinale and its processed products].

Zingiberis Rhizoma Recens, Zingiberis Rhizoma, ginger juice, Zingiberis Rhizoma Praeparatum and roasted ginger are derived from the rhizome of Zingiber officinale. They are commonly used herbs in clinical application, but their processing methods are completely different, leading to different properties and flavors, meridian distributions, and efficacy characteristics from the perspective of traditional Chinese medicine (TCM). In order to distinguish the clinical applications of different processed gingers, it's advisable to learn from Treatise on Febrile and Miscellaneous Diseases. Almost half of the prescriptions in the book contain Zingiber officinale, involving Zingiberis Rhizoma Recens, Zingiberis Rhizoma, ginger juice, Zingiberis Rhizoma Praeparatum and other species. In addition, many researches have confirmed that the contents of chemical compositions contained in different processed gingers were not exactly the same, and their pharmacological effects were also different, thus their applications could not be confused. However, physicians often encounter drug shortage or improper processing in clinical practice, contributing to the current chaotic use of different processed gingers. Therefore, this paper aims at sorting out the sources, processing methods, and chemical compositions, comparing their properties, flavors, meridian distributions, and pharmacological effects, and summarizing the efficacy characteristics and application rules in TCM theory of different processed products, with the hope to provide theoretical foundations for their reasonable use.

Pharmacological effects and clinical applications of Zingiber officinale and its processed products / 中国中药杂志

Zingiberis Rhizoma Recens, Zingiberis Rhizoma, ginger juice, Zingiberis Rhizoma Praeparatum and roasted ginger are derived from the rhizome of Zingiber officinale. They are commonly used herbs in clinical application, but their processing methods are completely different, leading to different properties and flavors, meridian distributions, and efficacy characteristics from the perspective of traditional Chinese medicine (TCM).

Research on the HPLC characteristic fingerprints of Rhizoma Pinelliae and processed products / 中国药学杂志

OBJECTIVE: To establish and compare the HPLC fingerprints of different parts of Rhizoma Pinelliae (RPI), Rhizoma Pinelliae Praeparatum Cum Alumine (RPA), Rhizoma Pinelliae Praeparatum Cum Zingibere Et Alumine (RPZ), Rhizoma Pinelliae Praeparatum (RPP) and Jing Pinelliae (JPI) and provide reliable method and scientific basis for their quality control. METHODS: The HPLC fingerprints of water, 75% ethanol and 95% ethanol extracts of Rhizoma Pinelliae and processed products were established and analyzed with Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(Version 2004A). RESULTS: The chromatograms of water, 75% ethanol and 95% ethanol extracts were generated as the representative standard fingerprints. Thirteen common peaks were obtained in the fingerprints of Rhizoma Pinelliae and Rhizoma Pinelliae Praeparatum Cum Alumine; 15 common peaks were obtained in the fingerprints of Rhizoma Pinelliae Praeparatum Cum Zingibere Et Alumine; 17 common peaks were obtained in the fingerprints of Rhizoma Pinelliae Praeparatum and Jing Pinelliae. Among the common peaks, 8 characterized peaks were identified as inosine, guanosine, adenosine, succinic acid, ephedrine hydrochloride, liquiritin, glycyrrhizic acid, and 6-Gingerol. Guanosine, adenosine, succinic acid, and ephedrine hydrochloride existed in Rhizoma Pinelliae and processed products. 6-gingerol was only detected in Rhizoma Pinelliae Praeparatum Cum Zingibere Et Alumine. Liquiritin and glycyrrhizic acid were detected in Rhizoma Pinelliae Praeparatum and Jing Pinelliae. A new peak (peak 8) appeared in the chromatograms of Rhizoma Pinelliae Praeparatum Cum Alumine and Rhizoma Pinelliae Praeparatum Cum Zingibere Et Alumine; Rhizoma Pinelliae Praeparatum and Jing Pinelliae did not show inosine and had a new peak (peak 11) compared to Rhizoma Pinelliae. CONCLUSION: This study established the HPLC characteristic fingerprints of different parts of Rhizoma Pinelliae and processed products. The method is stable, time-saving, reliable and can identify Rhizoma Pinelliae and its four different processed products, which provides a scientific basis for the quality control of Rhizoma Pinelliae.

Analysis and Comparison on Essential Oil of Rhizome Atractylodes Before and After Processing / 世界科学技术-中医药现代化

This study was aimed to analyze changes of content and quantity of essential oil of processing drugs of Rhizome Atractylodes and to achieve the impact of pyrolysis characteristics for using excipients, in order to offer evi-dences for further research and its processing technology. Steam distillation was used to extract essential oil in the Rhizome Atractylodes. Infrared spectroscopy and gas chromatography were used in the qualitative and quantitative analysis on constituents of essential oil of processing products of Rhizome Atractylodes. Thermogravimetric analysis was used in the comparison of pyrolysis characteristics between Rhizome Atractylodes and its excipients. The results showed that the content of essential oil was declined after processing. However, after being processed, the content of atractylodin was increased at different degrees compared to crude product. The change of atractylodin showed differ-ent tendency in different processing drugs. The atractylodin content from high to low was in the order of products stir-baked to yellowish, products roasted by bran, products prepared with rice water, crude drug. At the temperature of more than 220oC, excipients had major impact for the pyrolysis characteristics of Rhizome Atractylodes. It was concluded that the essential oil declined, but atractylodin increased after Rhizome Atractylodes being processed. It also provided experimental basis for further research on processing technology, ormulation of quality standard and improvement of processing mechanism.
