Further investigation of the aerial parts of Alomia myriadenia revealed an halimane diterpene identified as ent-8S,12S-epoxy-7R,16-dihydroxyhalima-5(10),13-dien-15,16-olide along with the known ent-16-hydroxylabda-7,13-dien-15,16-olide, ent-12R-hydroxylabda-7,13-dien-15,16-olide,
OBJECTIVE
To investigate the chemical constituents of Heteroplexis micocephal and their bioactivities.
METHODS
The constituents were isolated by using a combination of various chromatographic techniques including column chromatography over macroporous adsorbent resin, silica gel, Pharmadex LH-20,
