Bioactivity of marine organisms. Part 3. Screening of marine algae of Indian coast for biological activity

Abstract

Ethanolic extracts from Indian marine algae have been tested for anti-viral, anti-bacterial, anti-fungal, anti-fertility, hypoglycaemic and a wide range of pharmacological activities. Of 34 species investigated 17 appeared biologically active. Six were diuretic, 3 hypoglycaemic, 3 hypotensive, 4 exhibited anti- implantation activity, cytokinin activity was observed in one and one showed adrenergic blocking action. The extracts neither , had anti-bacterial, anti-fungal and anti-viral activities nor were toxic.
