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...

Oxalis corniculata Linn. is a medicinally important plant belonging to the family Oxalidaceae native to tropical and subtropical regions of the world. This paper briefly shows the botany, pharmacology, and therapeutic use of the herb. The review discloses that a varied array of phytochemical constituents have been extracted from the plant like glycosides, flavanoids, tannins, phytosterols, phenol, galactoglycero-lipid, volatile oil and fatty acids such as palmitic acid, oleic, linoleic, linolenic and stearic acids. The leaves contain flavonoids, isovitexine, and vitexine-2”- O- beta – D- glucopyrunoside. It holds essential activities like anti-inflammatory, anxiolytic, anti-epileptic, anti-fungal, anti-ulcer, anti-nociceptive, anti-cancer, anti-diabetic, hepatoprotective, anti-diarrhoeal, hypolipidemic, antioxidant, hypoli-pedemic, steroidogenic, cardioprotective, nephrotoxicity, diuretic, anti-microbial and wound healing has also been reported. These reports indicate that Oxalis corniculata has various therapeutic benefits and highlights the necessity for research and development on this...

The plant Withania somnifera has many acclaimed medicinal uses. This work aims to explore the efficacy of the aqueous extract (AE) of W. somnifera on the isolated trachea and aorta rings, perfused heart, blood pressure and diuresis in rats. Phytochemical analysis of the whole plant of W. somnifera was carried out using standard extraction procedures followed by column chromatography. An aqueous extract (AE) was also prepared by boiling the whole plant material in water followed by evaporation under reduced pressure. The smooth muscle relaxant effect of AE of W. somnifera (10-4 – 3×10-1 mg/mL) was tested on isolated rat tracheal and aortic rings. The effect of AE on heart rate and contractility of the isolated perfused heart were recorded. The hypotensive effect of AE (0.4-120 mg/kg) was recorded from the carotid artery in anesthetized normotensive rats. The diuretic activity of AE was evaluated in rats at two different doses (800 and 1600 mg/kg), and urine volume was measured throughout 24 h. Phytochemical analysis of the Jordanian locality of W....
