Plants are a potential source of natural antioxidants. Antioxidants protect from the potentially damaging oxidative stress, which is a result of an imbalance between the formation of ROS (Reactive oxygen species) and the body antioxidant defense. The present study was directed to investigate the antioxidant activity of methanolic extract of different plant parts of Cocculus hirsutus. The antiox...

Antioxidant activities of ethanolic extracts of Ardisia japonica Blume., Ageartum conyzoides Linn., and Cocculus hirsutus Linn Diels. leaves was determined qualitatively and quantitatively in this research. 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical solution was used to investigate free radical scavenging activity of these leaves extracts. Ascorbic acid (Vitamin C) was used as the stand...

Cocculus hirsutus Linn was studied for antimicrobial activity against Staphylococcus aureus, Echerchia coli, Pseudomonas aeruginosa and Salmonella typhi using agar disc-diffusion method. Petroleum ether extract, Ethanolic extract and Crude alkaloidal fraction were screened for the activity in various concentrations and zone of inhibitions were recorded. Results suggest that the Ethanolic extrac...

Sand flies were collected in the central region of the state of Rondônia (W 64 degrees 30' to 63 degrees 00' and S 10 degrees 00'to 11 degrees 00') using Shannon and CDC light traps from October 1997 to August 2000. A total of 85,850 specimens representing 78 named species were captured. Of these 14 were new records for Rondônia. The proportion of males/females was 1/1.131. Trypanosomatids, tha...

The roots of Cocculus hirsutus (Linn) Diels was analyzed for preliminary phytochemical studies including physical constant (total ash, acid soluble and insoluble ash and moisture content), extractive values in different solvents (petroleum ether, benzene, chloroform, methanol and water), and phytochemical tests. The plant is well reputed in traditional system of medicine, present studies will h...

Sauropus androgynus (Euphorbiaceae) is a popular vegetable in Thailand. In 1995, the plant was associated with several cases of poisoning when used in a Taiwanese weight control method and the toxicity was attributed to its alkaloid content. We have therefore investigated a closely related Sauropus species, S. hirsutus. Extraction and isolation of chemical constituents from the aerial part of S...

An atypical new species of Hypocaccus C. Thomson, H. hirsutus sp. nov. from south India is described and figured, but left unassigned to a subgenus. Current problems of taxonomy, morphological characters and inter-relationships of Hypocaccus subgenera are discussed and notes on the distribution of Hypocaccus C. Thomson, 1867 in India are given.
