- Abstract
The phytochemical investigations on Amoora ouangtliensis and A. stellato-squamosa were conducted in order to look for bioactive compounds. Nine diterpenoids were obtained by the method of column chromatography, and on the basis of spectral analysis they were identified as 8(17), 13 (E)-labdadien-15,19-dioic acid(1), methyl 8(17), 13(E)- labdadien-19-oic acid-15-oate (2), 15-acetoxy-8 (17), 13 (E)-labdadien-19-oic acid(3), 15-hydroxy-8 (17), 13 (E) - labdadien-19-oic acid (4), 8 (17), 13 (E)-labdadien-15,19-diol (5), 19-hydroxy-8 (17), 13 (E)-labdadien-15-al (6), 19-hydroxy-8 (17), 13 (Z)-labdadien-15-al(7), 8(17), 13 (E)-labdadien-19-oic acid-15-al(8), 8(17), 13 (Z)-labdadien-19-oic acid-15-al (9), and six other compounds, (+)-catechin (10), β-amyrin (11), stigmast-5-en-3β, 7α-diol (12), scopoletin (13), β-sitosterol(14), daucosterol(15). This is the first report of labdane-type diterpene from the genus Amoora.
