Abstract: Different extractives of leaf of Calliandra surinamensis were evaluated for antimicrobial activity along with membrane stabilizing, thrombolytic and cytotoxic activities. The total phenolic content was also determined and expressed in gallic acid equivalent. The membrane stabilizing activity was assessed by heat and hypotonic solution induced method. In the present studies, the crude methanolic extract (ME) of leaf of C. surinamensis demonstrated strong membrane stabilizing activity, whereas its chloroform (CSF) and pet ether (PESF) soluble fractions revealed moderate membrane stabilizing properties. In brine shrimp bioassay, the aqueous (AQSF) soluble fractions revealed the highest lethality. In antimicrobial screening, the choloroform (CSF) and aqueous (AQSF) soluble fraction demonstrated strong antimicrobial activity against 13 pathogenic microorganisms. The chloroform (CSF) soluble fraction exhibited the highest inhibition against microbial growth having zone of inhibition ranged from 13.0±0.82 mm to 18.3±1.25 mm and maximum zone of inhibition was found 18.3±1.25 mm against Salmonella typhi. In thrombolytic study, the chloroform (CSF) soluble fraction demonstrated mild thrombolytic activity in human blood specimen.

Investigation of the Pharmacognostical, Phytochemical and Antioxidant Studies of Plant Withania Coagulans Dunal


Author: Chetan Salwaan, Amrinder Singh, Anuj Mittal, Prabhsimran Singh

Abstract: The importance of traditional medicinal plants is increasing now a days because of various advantages over the synthetic drugs. Withania Coagulans dunal was studied for its antioxidant activity. Various physicochemical parameters were studied such as ash value, total ash, acid insoluble ash, water soluble ash, sulphated ash alcohol soluble extractive value etc. Various qualitative phytochemical tests were done for the presence of alkaloids, glycosides, carbohydrates, flavonoids etc. It was observed that 50% ethanol extract of withania coagulans contains carbohydrates, proteins, glycosides, steroids and sterols, anthraquinones and triterpenoids. The anti oxidant activity of Withania coagulans dunal was studied by DPPH and Nitric oxide method and it was observed that it has anti oxidant activity. It showed more activity in DPPH method than Nitric oxide method. Preliminary Phytochemical study of 50% ethanolic extract of the root parts is found to contain carbohydrates, protein, some steroids, anthraquinone, flavonoids, tannin, phenolic compounds and triterpenoids are present. The antioxidant activity was determined and the plant extract showed low activity nitric oxide free radical inhibition method and moderate activity by DPPH method. The activity was compared with rutin and ascorbic acid.

Phytochemical, Ethnobotanical and Pharmacological Profile of Lagenaria siceraria: - A Review


Author: Amit Kumar*, Sangh Partap, Neeraj K. Sharma

Abstract: In traditional systems of medicine, different parts (leaves, stem, flower, root, seeds and even whole plant) of lagenaria siceraria (known as lauki in Hindi), has been used in the ointment for ailment of various diseases throughout India. The fruit of cultivated lagenaria siceraria is the good source of different nutrients components like protein, fat, fibre, carbohydrates, calcium, magnesium. The plant has also been suggested to possess antioxidant activity, laxative, cardioprotective, diuretic, hepatoprotective, hypolipidemic, central nervous system stimulant, anthelmentic, antihypertensive, immunosuppressive analgesic, adaptogenic and free radical scavenging  activity. This work reviews the pharmacological evidence of extracts of plants from the lagenaria siceraria, giving an overview of the most studied biological effects and the known phytochemical composition. Although more studies are necessary, lagenaria siceraria exhibits proven potential to become of important pharmacological interest.
