Two new nortriterpenoids from the fruiting bodies of Ganoderma daqingshanense

Publication date: December 2017 Source:Phytochemistry Letters, Volume 22 Author(s): Ning Ning Lan, Qing Yun Ma, Fan Dong Kong, Ning Ning Yang, Qing Yi Xie, Sheng Zhuo Huang, Li Man Zhou, You Gen Wu, You Xing Zhao Two new nortriterpenoids named daqingshones A (1) and B (2), along with two known ganderic acids (3 and 4), were isolated from the fruiting bodies of Ganoderma daqingshanense. Their structures were elucidated by spectroscopic data including MS, 1D and 2D NMR. Compound 2 exhibited weak anti-acetylcholinesterase (AChE) activity with IC50 value of 39.2μM. Graphical abstract
