Eight new oleanane saponins (1- 8) together with four know saponins (9-12) were isolated from the aerial parts of Meryta denhamii. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The
The anthelmintic activity of the ethanolic extracts of stems and leaves of Meryta denhamii Seem. against adult liver flukes "Fasciola gigantica" was studied in vitro. Although leaves extract was inactive, stems extract exhibited anthelmintic activity and recorded LC50 and LC90 values, 16 and 26 gm/l
