title: [Cassae-type diterpenes from seeds of Caesalpinia minax].
abstract: Fifteen cassaen-type diterpenes were isolated from the 95% ethanolic extract of the seeds of C. minax through various chromatographic techniques. Their structures were identified on the basis of spectroscopic data as pulcherralpin (1), caesalpinin ML (2), chamaetexane C (3), chamaetexane D (4), 6β, 18-diacetoxycassan-13, 15-diene (5), neocaesalpin K (6), neocaesalpin MP (7), neocaesalpin M (8), neocaesalpin Q (9), neocaesalpin P (10), neocaesalpin R (11), caesaldekarin D (12), caesaldekarin A (13), caesaldekarin b (14), 3β,6α-diacetoxyvouacapane (15). Among them, compounds 14, 9-11 were isolated from this plant for the first time.
