Abstract:
Microspora floccosa
(Vaucher) Thuret [= Prolifera floccosa Vaucher], a filamentous
green alga was collected from River Indus at Power House Station, near
Hyderabad and extracted with methanol. The extract displayed a strong
antimicrobial activity against 14 bacterial and 20 fungal species.
Eleven saturated and 11 unsaturated fatty acids were found in the
extracts where former were lesser in quantity (47.4 %) than the latter
ones (52.6 %). Palmitic acid (C 16:0) was present in the highest amount
(12.3 %), while oleic acid (C 18:1) was detected in an appreciable
proportion (6.1 %). Two sterols and two terpenes were also obtained from
the extract, which were chemically elucidated as cholesterol,
24-isopropyl-5-cholesten-3β-ol, trans-phytol and
cyclopterospermol.
