Abstract

The stems of W. trilobata were collected in District 7, HCM City. From the petroleum ether, one compound isolated is 3a-tigloyloxy-9b-hydroxy-ent-kaur-16-en-19-oic acid (4). From the chloroform, three compounds isolated are 5-hydroxymethylfurfuran (1), 4-hydroxy-3-methoxybenzoic acid (2), ent-kaura-9 acid (11), 16-dien-19-oic (3). Among them, two compounds (1) and (2) are first found in W. trilobata.
