    ABSTRACT: Aim:Valeriana hardwickii Wall. belongs to family Valerianaceae grown in high altitude areas of north west Himalaya to Bhutan. Traditionally, the roots of the plant are used to treat insomnia; however, no reports are available regarding any pharmacognostic work on this plant. Material and Methods: The study includes morphological, microscopic and preliminary phytochemical investigations of the roots and rhizome. Anatomical studies of roots and rhizome shows the presence of diagnostic characters such as thick walled cortex cells, annular xylem fi ber, pitted xylem vessel and rhizome hair. Results: The preliminary phytochemical screening of petroleum ether, dichlomethane and aqueous extract revealed the presence of tritepenoids, alkaloids, irridoidal glycosides and fl avanoids. The study was carried out as per WHO guidelines. Conclusion: The outcome of this work will help the researchers to differentiate V. hardwickii from the other species of valerian

    ABSTRACT: Objective: In this study anti-tubercular (Anti-TB) drugs (isoniazid [INH] and rifampicin [RMP]) induced liver toxicity has been studied for the hepatoprotective effect of hydroethanolic extract of Calotropis procera (CP) flowers in rats. Materials and Methods: Animals were divided into four groups, group A was given normal saline (1 ml/kg), group B received INH (50 mg/kg) and RMP (100 mg/kg) group C received INH (50 mg/kg), RMP (100 mg/kg) and CP (150 mg/kg) orally for 14 days. Results: Biochemical markers of liver toxicity such as aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), and bilirubin and tissue histology were done inall groups. Anti-TB drugs (INH 50 mg/kg and RMP 100 mg/kg) have enhanced the ALT, AST, ALP, bilirubin and histological changes in liver, whereas co-administration of anti-TB drugs with CP has reduced these levels within the normal range. Conclusion: Findings of this study showed the hepatoprotective effect of CP against INH and RMP administration to reduce the liver damage for chronic treatment.

    ABSTRACT: Oroxylum indicum is a frequently reported traditional medicinal plant known to possess antiproliferative and antitumor activity. The present study investigated the effect of crude methanolic bark extract of Oroxylum indicum on testosterone induced benign prostate hyperplasia (BPH) in rat. Adult male rats were given either corn oil or testosterone dissolved in corn oil and testosterone with aqueous methanolic bark extracts of Oroxylum indicum (10, 50 and 100 mg/kg/day) for 14 days. The inhibitory effect of Oroxylum indicum on testosterone induced hyperplasia was evaluated by prostatic index and histopathological examination. Serum marker of liver injury (alanine aminotransferase, ALT and aspartate aminotransferase, AST) and liver histopathological examination were also conducted. Compared with testosterone induced BPH model group, Oroxylum indicum extract treated groups exhibited significant reduction in the prostatic index. Oroxylum indicum treated group also exhibited reduced hyperplasia of prostatic epithelium likewise finasteride treated group. Aqueous methanolic extract of Oroxylum indicum significantly inhibited testosterone induced prostate hyperplasia thus indicated the presence of efficient ingredients which can be used for the treatment of BPH.

    ABSTRACT: Background: Benincasa hispida (Thunb.) Cogn. is an extensive climbing annual herb in an agricultural country like India. Lupeol, a constituent of this species, has been reported to possess good amount of pharmacological potential. Objective: In the current studies, the research team focused on determining the percentage of the lupeol present in the extract of Benincasa hispida seeds by chromatographic techniques. Materials and Methods: Shade-dried seeds of Benincasa hispida were subjected to soxhlet extraction followed by scrutinization of the lupeol contents by HPTLC and HPLC methods after carrying out preliminary phytochemical screening for the constituents present in the extract. Results: The extraction yield was found to be 1.2% (w/w). Phytochemical screening of the extract revealed the presence of carbohydrates, glycosides, alkaloids, fixed oils and fats, tannins phenolic compounds, steroids and flavonoids. The amount of lupeol present in the seeds extract was found to be 0.47% w/w (HPTLC)and 6.85% w/v (HPLC) by HPTLC quantification and HPLC analysis respectively. Research studies showed a peak which coincided with the peak of standard lupeol signifying the presence of lupeol in the extract. Conclusion: The extract contains significant amount of lupeol.

    ABSTRACT: Objectives: The present study was designed to investigate the potential role of hydroethanolic root extracts were Rhus mysurensis (HERM) in the treatment of diabetes along with its antioxidant and antihyperlipidemic effects was studied in streptozotocin induced diabetes in Wistar rats. Methods: In this study, the anti-diabetic, hypolipidemic and anti-oxidant activities of hydroethanolic root extract of Rhus mysurensis was evaluated by using STZ induced diabetic rats at a dose of 200 mg/kg, 400 mg/kg and 800 mg/kg p.o. daily for 21 days. Blood glucose levels and body weight were monitored at specific time intervals, and different biochemical parameters, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein were also assessed in the experimental animals. Results: Oral administration of hydroethanolic root extracts of Rhus mysurensis (HERM) 400 and 800 mg/kg for 21 days significantly decreased the blood glucose level and considerably increased the body weight of diabetic induced rats. Daily oral treatment with HERM for 3 weeks resulted in reduced serum cholesterol, and triglycerides and improved HDL-cholesterol levels when compared to the diabetic control group. HERM significantly decreased thiobarbituric acid reactive substances (TBARS) and significantly increased superoxide dismutase and catalase in streptozotocin-induced diabetic rats at the end of 21 days of treatment. Conclusion: Hydroethanolic root extract of Rhus mysurensis showed significant anti-diabetic, hypolipidemic and anti-oxidant activities, which provide the scientific proof for its traditional claims. The results also put forward that the HERM is promising for development of standardized phytomedicine for the treatment of diabetes mellitus.

    ABSTRACT: Introduction: Capsicum frutescens is a well known spice. Leaves and fruits of the species are used in Ayurveda, Unani and Traditional system of medicines to cure various disorders. Therefore the study was aimed to investigate pharmacognostic parameters of C. frutescens leaf and fruit. Methods: Pharmacognostic studies were carried out in terms of morphological, microscopic characters and physicochemical parameters of C. frutescens samples using standard methods. Results: Smaller fruit size and color of C. frutescens was the distinguishing morphological character observed in the present study. The detailed microscopy of leaf confirmed the presence of rod shaped calcium oxalate crystals, oleoresin cells, pitted parenchyma and fruits with specified oleoresin, sclereid and stone cells with unicellular trichomes on persistent calyx. Physicochemical parameters like ash values, extractive values and nutritive values were determined. Fluorescence analysis of both leaf and fruit powder was determined using organic and inorganic solvents. Preliminary phytochemical screening showed the presence of alkaloids, glycosides, steroids, carbohydrates and proteins. Conclusion: Observed pharmacognostic characters in this study may help in identification and standardization of C. frutescens leaf and fruit.
