Abstract Aim The aim of present work was to study the pharmacognostic standardization, physicochemical, phytochemical and pharmacological evaluation of the stem of Bacopa monnieri L. Method Standard method was followed for pharmacognostic, physicochemical, and phytochemical study. For quantitative analysis, HPTLC technique was employed. Maximal electroconvulsive shock (MES) and pentylenetetrazole (PTZ) method was used for anticonvulsant evaluation. Result Microscopic study of the stem showed presence of epidermis and cortex having large intercellular spaces. The oval shaped starch grains were present in cells of cortex and endodermis. Total ash (5.98%), water-soluble ash (4.91%), acid-insoluble ash (3.96%), water soluble extractive (15.31%) and ethanol soluble extractive (6.74%) values were evaluated for physicochemical evaluations. Quantitative estimation of Bacoside A (marker compound) by HPTLC technique was performed. The linearity (100–600 ng), the % recovery (97.81% w/w) were estimated. The Bacoside A in the alcoholic extract was found to be higher than that of the other extracts. The proposed HPTLC method was found to be simple and accurate. The anticonvulsant activities of all the extracts were evaluated by MES and PTZ models in mice. Conclusion The least anticonvulsant potential was recorded for acetone extract in dose of 100 mg/kg and maximum anticonvulsant action was recorded for ethanolic extract in dose of 300 mg/kg.

Abstract The use of herbs as medicine is an ancient form of healthcare known to mankind. Standardization of herbal medicines is however a challenging task and is the major bottleneck in their acceptance as the primary therapeutic option. The aim of this study was to develop and validate a simple, rapid HPLC method for standardizing the mixture of extracts of three Medhya Rasayanas (neurotonic), Convolvulus pluricaulis, Withania somnifera and Bacopa monnieri. Simultaneous estimation of the respective bioactive markers of these plants viz., scopoletin, withaferin A, bacoside A 3, bacopaside II, jujubogenin and bacosaponin C has been reported for the first time. The method was developed using Waters Hybrid X-Bridge shield with BEH technology 2.5 μm, 4.6 × 75 mm column and validated according to ICH guidelines. The 20 minutes run time makes the method eco-friendly. The method was linear over a range of 12.5–400 ng/10 μL for scopoletin and 62.5–2,000 ng/10 μL for withaferin A, bacoside A 3, bacopaside II, jujubogenin and bacosaponin C with detection limits of 8.0, 48.3, 30.4, 40.7, 15.6 and 18.9 ng/10 μL and quantification limits of 24.5, 146.5, 92.2, 123.4, 47.4 and 57.4 ng/10 μL, respectively. The correlation coefficient for each analyte was >0.999. The intra-day and inter-day precision was <2%. These results confirmed the precision, accuracy and robustness of the proposed method.
