Isolation and structure elucidation of 12beta-acetoxycoccinic Acid, 12beta-hydroxycoccinic Acid, 12alpha-acetoxycoccinic Acid, and 12alpha-hydroxycoccinic acid1.
Four new triterpenoid acids, possessing a lanost-9(11)-en-3-one skeleton, were isolated from KADSURA HETEROCLITA. Based on chemical and spectral analyses, they were assigned as 12beta-acetoxycoccinic acid, 12beta-hydroxycoccinic acid, 12alpha-acetoxycoccinic acid, and 12alpha-hydroxycoccinic acid.
