ABSTRACT
The purpose of this experiment was to increase poultry meat production by increasing the number of chickens reared in the same area and managing it by using medicinal herbs Salvia officinalis L and Lavandula angustifolia L. in the broiler chicken diet. 705 one-day-old chicks were randomly distributed into to7 treatments with three replicates for an area of two m2 floor system in each replicate for each treatment, during 35 days of the study. T0 negative control 75 chicks, 25 chicks for each replicate 12-13 chicks per m2 fed standard diet. T1 positive control (stocking density without supplementation)105 chicks, 35 each replicate chicks 17-18 per m2 fed standard diet. The same stocking density for T2, T3, T4, T5, and T6 have been given standard feed with supplemented herbals, salvia 0.7%, 0.9%, lavender0.7%, 0.9%, and mixed 0.7% respectively. Depending on the results, chickens reared in stress stocking density with supplementations led to higher improvement of body weight, meat production, body weight gain (BWG), feed conversion ratio(FCR g feed/g weight), production index PI, carcass weight (g) and dressing percentage, RBCs 106cells/mm3, lymphocyte%, of increasing activity of thyroid hormones T3, T4 (nmol/L) boost antibody titers of ND and IBV when compared with positive control. However, heterophil%, stress indicator H/L ratio, glucose mg/ dL and cholesterol mg/ dL significantly reduced. The results showed that adding sage and lavender plants to broiler feed is effective in improving productivity, immunity, and resistance characteristics in reducing the adverse effects of stress caused by increasing the intensity of broiler rearing in the same area.
ABSTRACT
Radix Salvia miltiorrhiza (Danshen) is a Chinese herbal used in China to treat irregular menstruation, dysmenorrhea, insomnia, swelling liver, and angina pectoris. It also has various pharmacological activities, including anti-inflammation, anti-oxidation, anti-tumor, anti-atherogenesis, and anti-diabetes. However, traditional Chinese medicine (TCM), e.g., Danshen, lacks quality control. Pesticide residues and heavy metals are the most important problems, although Danshen may cure many diseases, even SARS-CoV-2 in a COVID-19 pandemic. Hence, the present short commentary discusses the background of Danshen, quality management, and its application to COVID-19.
ABSTRACT
Since the main symptoms of COVID-19 involve the respiratory system, the infection rate of this disease is predicted to be higher in patients with other respiratory conditions such as allergic rhinitis. In such a situation, it will be meaningful to conduct research on an allergy treatment that has fewer side effects and can effectively reduce allergy symptoms. Here, we prepared experimental samples under various fermentation conditions with mixed extracts of six medicinal plants. To examine the anti-allergic efficacy of these samples, an egg albumin-induced allergic rhinitis animal model experiment, a serum histamine and IgE experiment, and a COX and LO inhibitory activity experiment were conducted. As a result of animal experiments, OVA+SP-4 showed superior efficacy compared to OVA+SP-1 in nasal rubbing and sneezing experiments and had anti-allergic efficacy similar to that of OVA-cetirizine. The serum histamine concentration of OVA+SP-4 was also 1.3 times higher than that of the OVA+cetirizine group, showing a high histamine reduction ability, and IgE showed the same trend. An analysis of COX inhibitory efficacy also confirmed that COX-1 and COX-2 inhibitory efficacy is high, and the longer the fermentation time, the higher the antiallergic efficacy. The composition proposed by this study is expected to have a significant effect on sustainable allergy prevention and treatment in the future by applying it to human patients.

ABSTRACT
In the current pandemic caused by the new coronavirus (SARS-CoV-2), computational drug discovery can play an essential role in finding potential therapeutic agents. Thanks to its anti-viral, antibacterial, and anti-inflammatory properties, sage (Salvia officinalis) is used in traditional medicine. In this study, drugs proposed against COVID-19, including Lopinavir, Remdesivir, Favipiravir, and main flavonoids of sage, were docked favorably against novel coronavirus main protease. Molecular docking findings indicate that Rutin, Luteolin-7-glucoside, Apigenin, and Hispidulin make strong interactions with better binding affinity than selected commercial drugs in the study. But Rutin is the only flavonoid that makes strong hydrogen bond interactions with catalytic dyad and crucial Mpro residues and has more binding affinity than protease inhibitor PF-07321332 as an oral antiviral (PAXLOVID™). Further analysis of Molecular Dynamics and MM-PBSA predicted that chosen ligands could form stable complexes with the main protease. Also, ADMET analysis shows that main flavonoids are expected to have appropriate pharmacokinetic and no toxic properties. The results of the in silico study suggest that Salvia officinalis as a rich source of potent anti-coronavirus flavonoids may play a significant role in counteracting the replication of SARS-CoV-2.Communicated by Ramaswamy H.

ABSTRACT
Salvia officinalis (sage) attracts attention as it is widely cultivated on the territory of Ukraine. It is known that it has long been used in traditional medicine, as it contains large amounts of borneol, camphor, caryophyllene, cineole, ale, humulene, chilling, pinene and thujone. The purpose of this review is to collect and analyze information on the relevance of using the medicinal properties of raw Salvia officinalis (sage), since it reveals oncoprotective, antimutagenic, antioxidant, hepatoprotective, anti-inflammatory, antimicrobial, antifungal action, normalizes metabolic processes, and has successfully proven itself in the composition of cosmeceuticals. Taking into account the current COVID-19 pandemic situation in the world, as well as the anti-inflammatory, antimicrobial, antiviral properties of Salvia officinalis (sage), its positive effect on the normalization of the level of lipid peroxidation, antioxidant enzymes (superoxide dismutase and catalase), as well as a significant effect on reducing pulmonary fibrosis, dosage forms based on Salvia officinalis, can be used for prevention, comprehensive treatment and rehabilitation after a COVID-19 infection. The analysis of the pharmaceutical market showed that in Ukraine, medicines based on Salvia officinalis are used in the treatment of diseases of the upper respiratory tract, as well as in climacteric syndrome and psychoemotional stress, in the complex therapy of chronic diseases of the gastrointestinal tract and genitourinary system. The collected and systematized information indicates that medicinal plant Salvia officinalis (sage) can be used in a more diverse way. Therefore, we consider it expedient to further study the pharmacological properties of Salvia officinalis and develop a technology for the manufacture of new dosage forms for internal use based on it.
ABSTRACT
In this present study, commertially available Salvia triloba L., S.officinalis L., and S. sclarea L. essential oils were evaluated for their in vitro angiotensin converting enzyme 2 (ACE2) inhibitory activity. The Salvia essential oils compositions were confirmed both by GC-FID and GC/MS. Main components of the S. triloba essential oil was characterized as 1,8-cineole (22.8%), camphor (17.2%), α-thujone (15.2 %), β-caryophyllene (11.4 %), and α-humulene (3%). Major constiutents were identified as α-thujone (28.5 %), camphor (20.6 %), 1,8-cineole (10.9%), α-humulene (5%), and camphene (4.9 %) in S. officinalis essential oil. Whereas, linalylacetate (56.8 %), linalool (21.1%), α-terpineol (6.1%), geraniol (5%), and β-caryophyllene (3.4%) were the major components of S. sclarea essential oil. The essential oils were evaluated using a fluorometric multiplate based enzyme inhibition kit, where the ACE2 inhi-bitions of S. triloba, S. officinalis, and S. sclarea essential oils were 50.1%, 60.5%, and 72.1% at a concentration of 20 µg/mL, respectively. As a result, further tests of Salvia essential oils supported by in vivo studies may have antiviral potential ap-plications against coronaviruses due to ACE2 enzyme inhibitions.
ABSTRACT
Respiratory viral infections are a major public health concern because of their global occurrence, ease of spread and considerable morbidity and mortality. Medical treatments for viral respiratory diseases primarily involve providing relief from symptoms like pain and discomfort rather than treating the infection. Very few antiviral medications have been approved with restrictive usage, high cost, unwanted side effects and limited availability. Plants with their unique metabolite composition and high remedial values offer unique preventive and therapeutic efficacy in treatment of viral infections. The present review is focused on the types and mode of action of plant secondary metabolites that have been used successfully ί in the treatment of infections caused by respiratory viruses like Influenza, SARS, MERS, RSV etc. Plant metabolites such as phenolics, alkaloids, terpenoids and oligosaccharides inhibit attachment and entry of the virus. Others such as flavonoids, viz quercetin and baicalein, alkaloids viz sanguinarine, berberine and emetine, specific lipids and fatty acids prevent viral replication and protein synthesis. These metabolites have the potential to be used as lead molecules that can be optimized to develop potent drugs for effectively combating pandemics caused by respiratory viruses.
ABSTRACT
Salvia grossheimii is a perennial herb with antidiabetic and cytotoxic constituents. In continuation of our study on S. grosshiemii to identify the bioactive phytochemicals, we have reported the characterization of seven undescribed triterpenoids. The aerial parts of the plant were extracted in dichloromethane and its constituents were isolated using chromatography techniques. The structures of compounds were identified using 1D, 2D NMR, and ESI-MS spectral data. Seven new oleanane- and ursane-type triterpenoids (1-7) were identified in S. grossheimii. The structures of 1-7 were characterized as; 2α-hydroxy-3ß-acetoxy-olean-9(11),12-diene (1), 2α-acetoxy-3ß-hydroxy-olean-9(11),12-diene (2), 3ß-acetoxy-olean-18-ene,2α,11α-diol (3), 2α-hydroxy-3ß-acetoxy-urs-9(11),12-diene (4), 2α-acetoxy-3ß-hydroxy-urs-9(11),12-diene (5), 2α,3ß-diacetoxy-urs-12-ene-11α,20ß-diol (6), 2α,3ß-diacetoxy-urs-9(11),12-diene-20ß-ol (7). Triterpenoids (2, 5, and 7) were intramolecular transesterification or dehydration products of their corresponding isomers or allylic alcohol in the C rings, respectively, produced in-situ during NMR spectroscopy. Virtual screening of 1-7 was performed with molecular docking analysis to identify the potential SARS-CoV-2 and α-glucosidase inhibitors using the smina molecular docking algorithm. The best binding energy values (kcal/mol) against COVID-19 main protease Mpro were calculated for 6 (-8.77) and 7 (-8.68), and the higher binding affinities toward human α-glucosidase were obtained for 2 (-9.39) and 6 (-8.63). This study suggests S. grossheimii as a rich source of bioactive triterpenoids and introduces new natural compounds. Considering the high binding energy values of 2, 6, and 7, these structures could be candidates for anti-COVID-19 and antidiabetic drug development in the future.
ABSTRACT
The novel Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) has emerged to be the reason behind the COVID-19 pandemic. It was discovered in Wuhan, China and then began spreading around the world, impacting the health of millions. Efforts for treatment have been hampered as there are no antiviral drugs that are effective against this virus. In the present study, we have explored the phytochemical constituents of Salvia plebeia R. Br., in terms of its binding affinity by targeting COVID-19 main protease (Mpro) using computational analysis. Molecular docking analysis was performed using PyRx software. The ADMET and drug-likeness properties of the top 10 compounds showing binding affinity greater than or equal to - 8.0 kcal/mol were analysed using pkCSM and DruLiTo, respectively. Based on the docking studies, it was confirmed that Rutin and Plebeiosides B were the most potent inhibitors of the main protease of SARS-CoV-2 with the best binding affinities of - 9.1 kcal/mol and - 8.9 kcal/mol, respectively. Further, the two compounds were analysed by studying their biological activity using the PASS webserver. Molecular dynamics simulation analysis was performed for the selected protein-ligand complexes to confirm their stability at 300 ns. MM-PBSA provided the basis for analyzing the affinity of the phytochemicals towards Mpro by calculating the binding energy, and secondary structure analysis indicated the stability of protease structure when it is bound to Rutin and Plebeiosides B. Altogether, the study identifies Rutin and Plebeiosides B to be potent Mpro inhibitors of SARS-CoV-2.

ABSTRACT
The Coronavirus disease 2019 (Covid-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has led to unprecedented challenges for human life. During this pandemic, Turkish people have used various herbal remedies for both the prevention of Covid-19 and the alleviate of its symptoms. The present study aimed to investigate the herbal remedies used to prevent Covid-19 in Turkey and to determine whether the usage of herbal remedies was associated with sociodemographic properties. A cross-sectional study using an online questionnaire was conducted between November and December 2020. A total of 871 individuals (15 years of age or older) who lived in various provinces of Turkey participated in this study. Analysis was made in SPSS version 26.0 software using the descriptive statistics and appropriate tests of statistical significance for the comparisons. About 54.4% (n=474) of the participants reported that they have used herbal remedies during the pandemic period. We identified a total of 45 plant species, the most frequently cited were ginger (Zingiber officinale Roscoe), linden (Tilia spp.), elderberry (Sambucus nigra L.), sage (Salvia spp.), and rosehip (Rosa canina L.), respectively. It has been found that the usage of herbal remedies was associated with several demographic variables. A considerable proportion of the participants reported the use of herbal remedies in order to prevent disease. This paper demonstrated the potential herbal remedies that can be used against Covid-19. Further research should be carried out to evaluate the efficacy of these medicinal plants and should control the flow of misleading information.
ABSTRACT
The essential oil (EO) of Salvia leucantha Cav. was isolated by steam distillation of the aerial parts collected in the South of Ecuador. Its physical properties were evaluated and the chemical composition of the oil was determined by GC-MS and GC-FID analyses using two chromatographic columns, DB-5ms and HP-INNOWax. Six major compounds were identified, namely, the sesquiterpenes 6.9-guaiadiene (19.14%), (E)-caryophyllene (16.80%), germacrene D (10.22%), (E)-ß-farnesene (10.00%), and bicyclogermacrene (7.52%), and the monoterpenoid bornyl acetate (14.74%). Furthermore, four pairs of enantiomers were determined by enantioselective GC-MS of the essential oil. (-)-germacrene D and (+)-α-pinene showed the highest enantiomeric excess (ee%). In an in vitro assay, the essential oil demonstrated an interesting inhibitory activity of the enzyme butyrylcholinesterase (BuChE), with an IC50 = 32.60 µg/mL, which is the highest determined for a Salvia species. In contrast, the oil was weakly active against acetylcholinesterase (AChE) with an IC50 > 250 µg/mL.
ABSTRACT
Critical care medicine is a medical specialty engaging the diagnosis and treatment of critically ill patients who have or are likely to have life-threatening organ failure. Sepsis, a life-threatening condition that arises when the body responds to infection, is currently the major cause of death in intensive care units (ICU). Although progress has been made in understanding the pathophysiology of sepsis, many drawbacks in sepsis treatment remains unresolved. For example, antimicrobial resistance, controversial of glucocorticoids use, prolonged duration of ICU care and the subsequent high cost of the treatment. Recent years have witnessed a growing trend of applying traditional Chinese medicine (TCM) in sepsis management. The TCM application emphasizes use of herbal formulation to balance immune responses to infection, which include clearing heat and toxin, promoting blood circulation and removing its stasis, enhancing gastrointestinal function, and strengthening body resistance. In this paper, we will provide an overview of the current status of Chinese herbal formulations, single herbs, and isolated compounds, as an add-on therapy to the standard Western treatment in the sepsis management. With the current trajectory of worldwide pandemic eruption of newly identified Coronavirus Disease-2019 (COVID-19), the adjuvant TCM therapy can be used in the ICU to treat critically ill patients infected with the novel coronavirus.

Nowadays, viral infection is considered a major cause of mortality all over the world such as covid-19 pandemic. In this context, searching for antiviral agents are major researchers interests. In this study, essential oils (EO) of Lavandula angustifolia (lavender) and Salvia officinalis (salvia) were subjected to combat avian influenza H5N1 virus. Laboratory trials were performed to identify Lavender and salvia EOs and evaluate their antioxidant, anti-inflammatory and antiviral activity against an avian influenza H5N1 virus. EOs were prepared by the hydrodistillation of air-dried plants and analyzed by GC-MS methods. The results revealed that salvia has the highest EOs yield 1.3% than lavender 1%. The dominant constituents of lavender EO were linalyl acetate and linalool while camphor and α-thujone were the dominant compounds of salvia. Both oils exhibited antioxidant activity in DPPH and ABTS and total antioxidant capacity assays. The results suggest the use of salvia and lavender EOs as effective natural anti-inflammatory, antioxidant and antiviral agents.
ABSTRACT
Salvia species have been widely used as medicinal plants and have played an important role in the treatment and recovery of individuals with COVID-19. In this study, we reported two newly identified whole chloroplast genome sequences of Salvia medicinal plants (Salvia yangii and Salvia miltiorrhiza f. alba) and compared them with those of seven other reported Salvia chloroplast genomes. These were proven to be highly similar in terms of overall size, genome structure, gene content, and gene order. We identified 10 mutation hot spots (trnK-rps16, atpH-atpI, psaA-ycf3, ndhC-trnV, ndhF, rpl32-trnL, ndhG-ndhI, rps15-ycf1, ycf1a, and ycf1b) as candidate DNA barcodes for Salvia. Additionally, we observed the transfer of nine large-sized chloroplast genome fragments, with a total size of 49,895 bp (accounting for 32.97% of the chloroplast genome), into the mitochondrial genome as they shared >97% sequence similarity. Phylogenetic analyses of the whole chloroplast genome provided a high resolution of Salvia. This study will pave the way for the identification and breeding of Salvia medicinal plants and further phylogenetic evolutionary research on them as well.
ABSTRACT
Dietary habits strongly influence our health status, mostly in terms of maintenance of the inflammatory/anti-inflammatory homeostasis. High fat and high sugar diets account for the development of a low-grade inflammation, which is the pathogenic common denominator of various chronic diseases. Severe Acute Respiratory Syndrome Coronavirus (SARS)-CoV2 (COVID-19) infection affects all ages and especially frail elderly people and a nutritional intervention seems to be crucial in the course of this pandemic. The present review describes the properties of some vegetal products and their derivatives, such as Lupin sp., garlic, salvia and extra virgin olive oil (EVOO) that can be exploited for their beneficial effects, as preventive and/or nutritional treatment of coronavirus disease SARS-CoV2. Lupin, salvia, garlic and EVOO share overlapping properties, such as anti-oxidant, anti-inflammatory and anti-viral activities. Quite importantly, these products and their derivatives are able to recover the expression of angiotensin converting enzyme expression 2 on cell membrane, otherwise suppressed by COVID-19 binding and entry into cytoplasm. Dietary administration of the above nutraceuticals or their extracts may play a preventive or nutritional role in the course of SARS-CoV2 infection, even including the effects of the lockdown and the condition of inflamm-ageing.
