Development of validated HPTLC methods for determination of triterpenoids and flavan-3-ols in leaf and stembark of Dubard.

Dubard is a highly reputed medicinal plant of Ayurveda. In the current study, High-performance Thin-layer chromatographic (HPTLC) techniques were established for the analysis of triterpenoids like lupeol (LU), betulinic acid (BA), epimeric flavan-3-ols (+)-catechin (CA), and (-)-epicatechin (ECA), in its leaf and stembark. HPTLC separation was performed using petroleum ether: ethyl acetate: toluene: formic acid (7:2:1:0.

Quality control methods for fruit extracts of using high performance thin layer chromatography.

is a tree native to Africa but also found in eastern and southern parts of India with reported anti-bacterial, anti-inflammatory, and immunomodulatory activities. Verbascoside, caffeic acid and ferulic acid are important markers for the quality control of the plant. Two different HPTLC methods were developed and validated; method - 1 for estimation of verbascoside and caffeic acid while method - 2 for estimation of caffeic acid and ferulic acid.

Screening of Natural Compounds as Potential Inhibitors of SARS-CoV-2 Main Protease and Spike RBD: Targets for COVID-19.

Historically, plants have been sought after as bio-factories for the production of diverse chemical compounds that offer a multitude of possibilities to cure diseases. To combat the current pandemic coronavirus disease 2019 (COVID-19), plant-based natural compounds are explored for their potential to inhibit the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the cause of COVID-19. The present study is aimed at the investigation of antiviral action of several groups of phytoconstituents against SARS-CoV-2 using a molecular docking approach to inhibit Main Protease (Mpro) (PDB code: 6LU7) and spike (S) glycoprotein receptor binding domain (RBD) to ACE2 (PDB code: 6M0J) of SARS-CoV-2.

Evaluation of efficacy of extract and its major constituent, mangiferin in streptozotocin (STZ)-induced diabetic rats.

Objectives: Based on the ethno-medicinal use of leaf, in the treatment of diabetes, the present study is aimed at evaluation of antidiabetic potential of leaf extract and its major constituent mangiferin.

Methods: Efficacy of hydroalcoholic extract of leaf (BCL, 200 and 400 mg/kg body wt.) and mangiferin (MF, 20 mg/kg body wt) was studied in streptozotocin (STZ)-induced diabetic rats and associated complications visually, retinopathy, cardiopathy and nephropathy.

Anti-inflammatory and immunomodulatory activities of Inula cappa roots (Compositae).

Background The medicinal properties of Inula cappa, a perennial shrub, are ascribed to its roots. In this article, we study the anti-inflammatory and immunomodulatory activities of I. cappa root extracts based on its utilization in traditional medicine-treatment of rheumatoid arthritis, menoxenia, fever, jaundice and many others.

Development and Validation of a Rapid LC-MS/MS Method for Simultaneous Determination of Kaempferol and Quercetin in Extract.

In this study, a simple and rapid LC with tandem MS method was developed and validated for the simultaneous determination of kaempferol and quercetin in Thespesia populnea extract. The compounds were eluted using a Gemini C18 column (50 × 2.0 mm, 3 μm), with the mobile phase consisting of acetonitrile-0.

Evaluation of antiulcer potential of Mimusops hexandra in experimental gastro duodenal ulcers.

The study was aimed to investigate antiulcer effects of acetone extract and its different fractions Mimusops hexandra against experimental gastro-duodenal ulcers. 80% acetone extract of stem bark of Mimusops hexandra (Extract A, p.o.

Hepatoprotective activity of punarnavashtak kwath, an Ayurvedic formulation, against CCl4-induced hepatotoxicity in rats and on the HepG2 cell line.

Objective: Punarnavashtak kwath (PNK) is a classical Ayurvedic formulation, mentioned in Ayurvedic literature Bhaishajya Ratnavali, for hepatic disorders and asthma. This study investigated the hepatoprotective activity of PNK to validate the traditional use of this formulation.

Materials And Methods: PNK was prepared in the laboratory according to the method given in Ayurvedic literature.

Evaluation of anti-inflammatory and antioxidant activity of Premna integrifolia root.

Roots of Premna integrifolia Linn. Mant. (Verbanacea) are important rasayana (Adaptogenic) drugs and are considered to be useful in the treatment of variety of ailments.

Involvement of the PI3K/AKT pathway in the hypoglycemic effects of saponins from Helicteres isora.
