Introduction: Picrorhiza kurroa is a well-known plant used in Ayurvedic medicines belonging to the family, Scrophul-ariaceae. This herb has been traditionally used in treating liver disorders, upper respiratory tract disorders, reduce fever, scorpion stings, and treat dyspepsia and chronic diarrhea. Experiment: The macroscopy, microscopy, powder microscopy, physiochemical screening was done on Picrorhiza kurroa roots. TLC, HPTLC. Results: The macroscopy, microscopy, and powder microscopy study reveals the identification of P. kurroa root. The phytochemical studies showed the presence of secondary active constituents such as phenols, glycosides, etc., TLC and HPTLC analysis showed that the chloroform fraction of P. kurroa has a higher number of peaks and spots compared to total...

Salacia chinensisis, commonly known as Saptarangi in the Hindi family of Hippocrateaceae, it is a woody climbing shrub found in Africa, Vietnam, and Thailand. A large number of biologically active compounds like salacinol, kotalanol, neokotalanol, neosalacinol, salasol, and mangiferin are isolated from S. chinensis. Traditionally, the plant is used in the treatment of diabetes, but there are few studies that demonstrate its use as anti-inflammatory, nephroprotective, anticancer, and treatment of cardiac disorders. The present study involves extraction, isolation, structural elucidation, and prediction of antioxidant activity from the roots of S. chinensis. The roots were extracted with water and methanol by using a hot extraction method. The methanol extract was fractionated with ethyl acetate. The antioxidant activity of different extracts was determined by 1, 1-diphenyl-2- picryl- hydrazyl (DPPH) method. The highest antioxidant activity was found in ethyl acetate extract, followed by methanol extract and water extract. Ethyl acetate extract showed maximum antioxidant activity, so the extract was used for the isolation of antioxidant compounds by column chromatography. The compound was...

Termites impart hazardous impacts on the ecosystem by causing severe damage to wooden components. They decrease crop yield, restrain the production of economically important trees, and destroy wooden buildings. The utilization of insecticidal plants provides a promising strategy for the control of insects. The undertaken study is intended to highlight the anti-termite potential of plant extracts as a promising strategy for termite control. Insecticidal potential of Alstonia scholaris and Salvadora oleiodes extract revealed by investigating their impact on mortality and tunneling activities of Microtermes obesi. Mortality of Microtermes obesi was investigated by treating the soil and filter paper with different concentrations of methanolic and aqueous extracts. Least LT50 value was shown by 40% methanolic extract of S. oleiodes i.e. 40.476 and 37.425 hours, in soil and filter paper assay, respectively. Termites showed least tunneling activity at 40% concentration of methanolic extract of S. oleiodes thus indicating that toxicity of phytochemicals might have apprehended the movement of termites. Methanolic extract of S. oleiodes showed grade 1 (v. v. strong) repellent...

Sphaeranthus indicus Linn (Asteraceae) is a popular and very useful plant used in Indian system of medicine. It is usually found in damp areas, plains and also as a weed in the rice fields. In the Ayurvedic system of medicine, the plant as a whole plant or its different parts like leaf, stem, bark, root, flower and seed are widely used for curing many diseases. The plant is enriched with various types of secondary metabolites such as eudesmanolides, sesquiterpenoids, sesquiterpene lactones, sesquiterpene acids, flavone glycosides, flavonoid C‑glycosides, isoflavone glycoside, sterols, sterol glycoside, alkaloid, peptide alkaloids, amino acids and sugars. Essential oil has been isolated from flowers and whole plant. In this present study, various methods are carried out to perform the evaluation of pharmacognostical parameters of crude drug as well as aqeous extract of aerial part of the plant which may forms the basis for the further use of the plant and also for the evaluation of its various pharmacological activity. The physicochemical evaluation confirms the quality and purity...

Background: Swertia chirayita (Roxb. ex Flem.) Karsten known as Kiratatikta in Ayurveda, the Indian indigenous health system, is used for various ailments like liver disorders, diabetes, fever, worm infestation, and others. Due to huge demand and non-availability, other Swertia species and other herbs are used as substitutes/adulterants for Swertia chirayita (Roxb. ex Flem.) Karsten. Hence, the present study is carried out with the objective of characterizing the macroscopic, microscopic features, the physicochemical and chromatographic profile of the herb. Material & Methods: Pharmacognostical parameters like microscopy, physico-chemical, phytochemical and chromato-graphic investigation for the whole plant of Swertia chirayita (Roxb. ex Flem.) Karsten was done using standard methodology. Results: The chief macroscopic features of the whole plant are wrinkled roots, quadrangular stem in the upper portion, leaves brittle, and presence of flowers and fruits. In powder microscopy, fragments of the epidermis with stomata, resin containing cells, pitted parenchyma, cells forming epidermis of fruit, parenchyma cells, pitted fibers, fragments of cotyledon, endosperm cells, sclereids were the key features. Phytochemical analysis revealed the...
