Abstract

This disceration describes the isolation and structural studies on the steroidal lactone withanolides from Withania coagulans of the solanaceae family. The work has resulted in the isolation of eight new withanolides along with four known withanolides. Extensive spectroscope techniques such as EI MS, FAB, MS, HREI MS, UV, IR 1H- and 13C-NMR (BB, DEPT, COSY-450, HMBC and HMQC) were employed to elucidate the structures of below compounds
