ZHOU Yan, PENG Shu-Lin, LI Chao-Luan, WANG Ming-Kui and DING Li-Sheng   


A new C-glycosylflavone, named panzhihuacycaside (1), was isolated from the leaves of Cycas panzhihuaensis L. Zhou et S. Y. Yang (Cycadaceae) along with 2,3-dihydrohinokiflavone (2), 5,5″,7,7″,4′,4-hexahydroxy-(2′,8″)-biflavone (3), vanillic acid (4),β-sitosterol (5) and daucosterol (6). Their structures were elucidated by spectral and chemical evidence.
