Bioassay-guided extraction and fractionation of the aqueous methanolic extract of the cones of Pinus densiflora (Pinaceae) afforded one new labdane-type diterpene aldehyde, 15-nor-14-oxolabda-8(17),12 E-diene-18-oic acid, along with eight known diterpenes. Their structures were elucidated using spectroscopic methods as well as by comparison with previously reported data. The isolates showed antibacterial (Propionibacterium acnes) and antifungal activities.
对赤松（松科）球果的甲醇水提取物进行生物测定导向的提取和分离，得到一种新的半日花烷型二萜醛，15-降-14-氧代半日花-8(17),12E-二烯-18-酸，以及八种已知的二萜。通过光谱方法并与先前报道的数据进行比较，阐明了它们的结构。分离物显示出抗菌（痤疮丙酸杆菌）和抗真菌活性。
