Abstract
Eleven new diterpenoids: pimaranes (1,2), rosanes (3) abietanes (4–7), icetexanes (8), and rearranged icetexanes (9–11), together with fifteen known diterpenes (12–26) and two known sesquiterpenes (27,28) have been isolated from the roots and twigs of Premna obtusifolia. The structures of these compounds were elucidated on the basis of spectroscopic analysis and X-ray crystallographic data of 8 and 9 were also determined. The antibacterial and anti-inflammatory activities of the isolates were evaluated.
