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.

The ancient wisdom in Ayurveda medicine is still not exhaustively explored. Multiple exotic plants existent in India which are not described in classical literature of Ayurveda are commonly referred to as Anukta Dravya (undocumented). Costus pictus D.Don is such a plant, recently introduced in India from Mexico, which is used for renal disorders there. In India, it is used in Diabetes mellitus. This is proven for antidiabetic, antioxidant, anticancerous, antimicrobial and diuretic actions. It is an easily propagated, palatable and cost effective plant. Identification through pharmacognostical and phytochemical studies is essential for the standardization of any plant. The green leaf is narrowly elliptic with 10 to 25cm length and 2.5 to 6cm width. Microscopy revealed presence of vascular bundles, unicellular trichomes in upper epidermis, thin walled parenchyma cells in ground tissue and layers of parenchymatous hypodermis. Powder microscopy showed presence of epidermal parenchyma cells with underlying chlorenchyma group of fibers and fibro vascular bundles.TLC photo documentation revealed presence of many phytoconstituents with different Rf values. Densitometric scan showed many peaks, 10 at 254nm, 11 at 366nm, 6 at 520nm and 9 at 620 nm after derivatisation. Moisture content was 20%. The percentage of total ash, acid insoluble ash, and water insoluble ash was determined. The water soluble extractive value was 22.57 which is highest among all the extracts. The results indicated the presence of alkaloid, steroids, tannins, flavanoids, phenol, carbohydrate and resin in ethanolic extract and steroid, flavanoids, phenols, saponins, tannins and glycosides in water extract.

The alcoholic extract of unripe fruits of Musa paradisiaca Linn. (Musaceae) was evaluated for antianxiety activity by using operant behavior (behavioral disinhibition) model of anxiety in albino rats. Phytochemical investigation of alcoholic extract revealed the presence of flavonoids, amino acids,vitamins and carbohydrates. Alcoholic extract showed significant anti-punishment and anti-frustration activities at dose level of 500 mg/kg/day for 5 days which is comparable to standard drug, diazepam 5mg/kg. The presence of amino acid and flavonoids in alcoholic extract could be attributed for the antianxiety and other CNS depressant activity.

Aconitum heterophyllum is a traditionally important medicinal plant having numerous therapeutic actions as documented in Ayurveda. This plant has been used alone as well as in combination with other plants for the preparation of different anti-malarial formulations. However, there is no report on the assessment of its anti-plasmodial activity, and the compound responsible for this activity. The main aim of this study was to conduct phytochemical investigation of A. heterophyllum roots for the preparation of extract, fractions and isolation of pure molecules to identify active fractions/molecules responsible for the anti-plasmodial activity, and development of UHPLC-DAD based analytical method which can be used for the quantification of marker compounds in the extracts and fractions. Hydro-alcoholic extract (1:1 v/v) and fractions (n-hexane, chloroform, ethyl acetate, n-butanol and water) were prepared from the dried powdered roots of A. heterophyllum. Fractions were further subjected to silica gel-based column chromatography to isolate pure specialized secondary metabolites from this plant. All extracts, fractions and pure molecules were evaluated against the chloroquine resistant Pf INDO and chloroquine sensitive Pf3D7 strains in culture for calculating their IC50 values. UHPLC-DAD based analytical method was also developed for the first time for the quantification and quality assessment of this commercially important Himalayan medicinal plant. Phytochemical investigation of A. heterophyllum root led to the isolation of six specialized metabolites named as 2-O-cinnamoyl hetisine (1), atisinium (2), 4-oxabicyclo [3.2.2] nona-1(7),5,8-triene (3), atisinium cinnamate (4), aconitic acid (5), and atisinium formate (6). Compound 1 is a new hetisine type diterpenoid alkaloid, compounds 4 and 6 are new counter ionic forms observed with atisinium ion, and compound 3 is being reported for the first time from this genus. Chloroform fraction was found to be the most active with IC50 (µg/mL) 1.01 (Pf INDO) and 1.32 (Pf3D7). The isolated molecule 2-O-cinnamoyl hetisine (1), a new diterpenoid alkaloid isolated from chloroform fraction, showed promising antiplasmodial activities with IC50 (µM) 1.92 (Pf INDO) and 10.8 (Pf 3D7). Activity of chloroform fraction was further validated by the developed UHPLC-DAD based method as the quantity of 2-O-cinnamoyl hetisine (1) was higher in the chloroform fraction (≅200 µg/mL) than in all other fractions (< 7µg/mL). Atisinium (2) and 2-O-cinnamoyl hetisine (1) were found to be the main marker compounds of this plant based on quantity and antiplasmodial activity, respectively. This study provides the scientific rational for the traditional use of this plant in treating malaria. Further, this study revealed that anti-malarial potential of this plant might be due to the presence of diterpenoid alkaloids.
