From the aerial parts of Baccharis pingraea the known furolabdane, angeloyl-gutierrezianolic acid (1); two novel diterpenoids, furolabda-6,8-dien-17-oic acid (2) and furolabd-7-en-17-oic acid (3); and the known linear diterpenoid, (10E)-centipedic acid (4), were isolated. LC/MS suggested the presence of gutierrezianolic acid (5). The structures of the new compounds were elucidated by 1D and 2D NMR
从松果芽孢杆菌的地上部分可知已知的呋喃丹,呋喃丹-古铁雷斯烷酸(1)。两个新颖的二萜类化合物,furolabda-6,8-dien-17-oic acid(2)和furolabd-7-en-17-oic acid(3);并分离出已知的线性二萜(10E)-ipe酸(4)。LC / MS提示存在古铁雷斯酸(5)。通过1D和2D NMR方法阐明了新化合物的结构。
