A new biflavonoid named pancibiflavonol (1) was isolated from an EtOH extract of the stem bark of Calophyllum panciflorum, along with six known biflavonoids, and its structure was elucidated by spectroscopic methods. These biflavonoids all exhibited significant inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate-induced Epstein-Barr virus early antigen activation in Raji cells.
从多花红厚壳茎皮的乙醇提取物中分离出一种名为盘叶双黄酮醇（1）的新双黄酮，以及六种已知的双黄酮，并用光谱方法阐明了其结构。这些双黄酮均对12-O-十四酰佛波醇-13-乙酸酯诱导的Raji细胞中爱泼斯坦-巴尔病毒早期抗原激活表现出显著的抑制活性。
