Heliotropium indicum are used in ethnomedicine for treating skin rashes, inflammation, tumors and various diseases of microbial origin. Previous work focused on phytochemical constituents, antibacterial activities and isolated compounds. The whole plant was air dried and pulverized (600 g). It was extracted with ethanol and concentrated to dryness in vacuo (20 g). Screening for phytochemical groups was performed using qualitative methods. The antibacterial activity was performed using agar diffusion and antifungal activity using ditch plate method. Compounds were characterized using Gas-chromatography Mass Spectrometry. The results of the phytochemical screening revealed the presence of phenols, saponins, terpenoids and cardiac glycosides. The results further showed the crude extract of the plant to be moderate to strong antibacterial activity with zones of inhibition ranging from 12.0 + 1.6 mm and 25 +1.7 mm. the crude extracts of Heliotropium indicum demonstrated antibacterial properties which confirmed the traditional use of this plant in treating skin rashes and boil. In addition, the presence of Palmitate and Linoleic acid I the plant as revealed in this study justified the use of this plant in treating hypertension.

Objective: The present investigation includes the preliminary screening of phytochemicals and evaluation of in vitro antidiabetic activity of Psidium guajava leaves extracts. Materials and Methods: Plant material was subjected to the extraction preparation by soxhlet apparatus by using various solvents such as aqueous, ethanol, chloroform, petroleum ether and hexane. The various kinds of phytochemicals were detected and then in vitro antidiabetic activity of P. guajava were detected by using alpha amylase and alpha glucosidase enzyme in an in vitro model. Results: The study reveals the presence of phytochemicals such as carbohydrate, tannin, flavonoids, phenols etc., Among the various extracts the aqueous and ethanolic extracts which contains the large number of phytoconstituents. The P. guajava leaves has been successfully inhibited both the enzymes in an in vitro model. The aqueous extracts of P. guajava leaves inhibited the alpha amylase and alpha glucosidase enzymes as 72.1\% and 74.8\% respectively. The ethanolic extract of P. guajava leaves inhibited the alpha amylase and alpha glucosidase enzymes as 97.5\% and 91.8\% respectively. Conclusion: From the results obtained in the current studies, the P. guajava leaves have a prominent antidiabetic property in an in vitro model and further studies can be carried out in an in vivo model and the isolation of activie compound from P. guajava leaves extract is needed.

Objective: To evaluate the preliminary phytochemical analysis and in vitro- Antihelmenthic activity of leaf extract of Achyranthes aspera. Background: Achyranthes aspera is an annual, stiff-erect herb found commonly as a weed throughout India. The leaf ethyl acetate extract showed high larvicidal activity on the tick larvae of Rhipicephalus. It strengthen the liver and kidneys, strengthening muscles, tendons and bones, anti-inflammatory, anti-toxin, urine laxative, normalize menstruation, hemostatic, ease childbirth. Chemical Ingredients includes Akirantin, glokosa, galactose, reilosa, ramnosa, and alkaloids. Hentriakontan, sapogenin, Betaine, ecdysterone, triterpenoid saponins. Methods: Preliminary phytochemical analysis was done by adopting the method of Evans. Antihelmenthic assay is performed by standard protocol. Result: The present study reveals the presence of few secondary metabolites and the extract exhibitspotent Antihelmenthic activity. Conclusion: From the present study it can be concluded that Achyranthes aspera leaf extract possessed marked in vitro Anti helminthic effect.

Context:Bryophyllum pinnatum (Lam.) Kurz. widely used in traditional as well as folk medicinal systems is locally known as Panphuti. Traditionally it is used for the treatment of kidney stones, urinary tract infection, burns and diarrhoea. Aims: In the present study, pharmacognostic studies of root, stem and leaf of Bryophyllum pinnatum (Lam.) Kurz. is carried out in order to standardize the plant for its phytochemical, phyiso-chemical and pharmacognostical. Methods and Material: For standardization of plant material morphological and anatomical characterization was carried out. Physico-chemical parameters viz. ash content, extractive values, heavy metal content was carried out as per Ayurvedic Pharmacopoeia of India. Phytochemical investigations were made to know the presence of various bioactive molecules, amino acid composition. Results: Intrastelar and extrastelar secondary growth with wood and periderm formation along with deposition of starch grains were observed in pith region of root and cortical region of stem. Calcium oxalate crystals were also present in the cortical region of the stem. Leaf lamina showed spongy parenchyma in mesophyll region and anisocytic type of stomata. Anthocyanin pigment was present below epidermal cells in petiole. Physico- chemical results can be serves as quality control data. Quantitatively carbohydrate, protein, flavonoids, phenolic compounds, saponins and pro-antocyanidins were found to be present in root, stem and leaf part of Bryophyllum pinnatum (Lam.) Kurz. Conclusion: The results of the study could be useful in setting some diagnostic indices for the identification and preparation of a monograph of the plant.
