Abstract

From the stem and bark of the mangrove plant Hibiscus tiliaceus, a new friedelane‐type triterpene named 27‐oic‐3‐oxo‐28‐friedelanoic acid (1) together with eight known triterpenoids involving five friedelane‐type derivatives was isolated. The structure of 1 was determined by extensive 2D NMR (DQF‐COSY, HMQC, HMBC, and NOESY) data analyses. All the compounds were obtained from mangrove plants for the first time.
