作者对青霉属真菌Penicillium thiersii进行了以生物活性为导向的分离,得到了5个独特的天然产物,分别为oxalicine A(4)、oxalicine B(5)、15-de-oxyoxalicine A(6)、decaturin C(7)和decaturin D(8)。其中化合物6~8为新化合物。初步研究了这些化合物的抗昆虫作用。将从发酵大米
The authors isolated the Penicillium thiersii from the genus Penicillium thiersii with biological activity-oriented separation and obtained five unique natural products, oxalicine A (4), oxalicine B (5), and 15-de-oxyoxalicine A (6). Decaturin C(7) and Decaturin D(8). Compounds 6-8 are new compounds. Preliminary studies of the anti-insect effects of these compounds. Will ferment rice
