Abstract :

Three phenolic red pigments were observed in combination from the heart wood of Caesalpinia sappan (F: Caesalpiniaceae). Preliminary cytotoxic and acute toxicity studies indicated that these natural colour pigments were safe compared to the FDC grade coal tar dyes. The isolated colour extract (CSWC) was highly soluble in water and analysed by spectrophotometric and HPTLC methods.

Abstract : Comparative phytochemical and antibacterial activities of bark of Alstonia scholaris and Alstonia macrophylla were investigated. The successive different solvent extracts showed the presence of alkaloids, phenolics, saponins and tannins were found in both the species. The antibacterial activities of bark of A. scholaris and A. macrophylla in successive different solvent were tested against gram +ve and gram -ve organisms. The chloroform extracts of A. macrophylla showed broader spectrum of antibacterial activity when compared with A.

Abstract: Cardiospermum halicacabum L. (Sapindaceae) commonly known as “Balloon vine” is a dioecious, hairy, climbing vine with balloon like clusters of white flowers framed by finely dissected, delicate foliage. The leaf has a bitter taste; the entire plant is used as anti-inflammatory, antibiotic against many bacteria, antiparasitic, antipyretic and as an analgesic. The ethanolic extract of leaves exhibits significant anti-arthritic effect.

Abstract : Alpha glucosidase in-vitro inhibitory activity and hypoglycemic effect by oral administration in rats of Physalis minima ethanol extracts have been investigated. Physalis minima extract showed in-vitro inhibitory activity of intestinal alpha glucosiadase enzyme maltase. Analysis of data confirms that alpha glucosidase inhibition activity was maximum at 1000mcg/ml of Physalis minima.

Abstract : The aim of present study was to evaluate anthelmintic potential of anterdhum Padhati Mahi (APM) and Bahirdhum Padhati mashi (BPM) using Pheretima posthuma and Ascardia galli as test worms. Various concentrations (10 – 100 mg/ml) of APM and BPM were tested in the bioassay, which involved determination of time of paralysis (P) and time of death (D) of the worms. Piperazine citrate (10 mg/ml) was included as standard reference and distilled water as control.

Abstract : A total of 19 species of weeds in wheat fields representing 11 families were collected from the different region of Mahendergarh district of Haryana during the winter seasons of November 2007 to April 2008 and November 2008 to April 2009. The survey revealed that a significant number of weed species has an ethnomedicinal value, besides this some weeds are highly nutritious and their leaves may be used as food or herbal medicine.

Abstract: The antioxidant activity of the methanolic and aqueous extracts of Martynia annua Linn. leaves were evaluated by several in vitro systems of assay, namely, reducing power assay, DPPH radical-scavenging activity, nitric oxide scavenging activity, H2O2 radical scavenging activity, superoxide radical scavenging assay, hydroxyl radical-scavenging activity, and total antioxidant capacity. Total phenolic content was measured by Folin–Ciocalteau reagent.

Abstract : Aegle marmelos Linn. (Rutaceae) is reported to possess a number of medicinal properties including antidiarrhoeal, antimicrobial, antifungal and activities. The antiaflatoxigenic effects of ethanolic extract of the leaves of Aegle marmelos were studied on common aflatoxigenic fungal species. Aegle marmelos exhibited antifungal and antiaflatoxigenic activity at a concentration range of 0.5 to 2 mg/ml. The shake flask method was used to evaluate the antifungal and antiaflatoxigenic activity.
