| Abstract: | Two new compounds, a tricyclic-alpha,beta-unsaturate ketone (adenocaulone) (1) and a delta-hexanolactone glycoside (adenocaulolide) (2), along with 10 known compounds 3-12 were isolated from Adenocaulon himalaicum Edgew. Their structures were elucidated by spectroscopic methods (IR, MS, 1H, 13C and 2D NMR). In addition, the antibacterial activity of compounds 2, 3 and 4 were tested. |
