The resin of Pinus massoniana Lamb. contains, in addition to those isolated in an earlier study, two new diterpene acids, viz. 15-hydroxy-7,13-abietadien-12-on-18-oic acid and 8(14)-podocarpen-7,13-dion-18-oic acid, and three new plant products, viz. 2β-hydroxy-8,11,13-abietatrien-18-oic acid, 7,13,15-abietatrien-18-oic acid, and 13-hdyroxy-8,11,13-podocarpatrien-18-oic acid. The above acids and four
马尾松羔羊的树脂。除较早研究中分离出的那些外,还包含两种新的二萜酸,即。15-羟基-7,13-abietadien-12-on-18-oic酸和8(14)-罗汉松-7,13-dion-18-oic酸,以及三种新的植物产品,即。2β-羟基-8,11,13-松香三烯-18-酸,7,13,15-松香三烯-18-酸和13-羟基-8,11,13-十二烷基-十八碳烯酸。从树脂中分离出上述酸和其他四种酸作为对硝基苯酯,并从光谱学证据确定了它们的结构。还分离出了三个中性的二倍半萜和倍半萜。
