Ethnopharmacol., 9(2-3), 337-45 (English) 1983. CODEN: JOETD7. ISSN: 0378-8741. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 11 From the petroleum ether ext. of the bark of C. macrocarpum, b-sitosterol [83-46-5], stigmasterol [83-48-7], octacosan-1-ol [557-61-9] and an unsatd. dicarboxylic fatty acid with mol. formula of C16H26O4 were isolated and identified. The MeOH ext. was fractionated by chromatog. into five fractions (BBF1-BBF5) and from BBF4 a pure yellow compd. with m.p. 315-316° was isolated. I.v. administration of 1-3 mg/kg body wt. of the various exts. into normotensive male rats showed that the MeOH ext. and esp. the chromatog. fraction BBF4 had significant hypotensive activity with little or no effect on heart rate. .
