从从红树林植物木槿（Hibiscus tiliaceus）茎内分离的内生真菌红色散囊菌（Eurotium rubrum）的液体发酵液中分离并鉴定了一种新的螺环二酮哌嗪生物碱7-O-甲基杂色色素A（1）和最近报道的已知化合物杂色色素A-C（2-4）。这些化合物的结构通过对其光谱数据的广泛分析来确定。
A new spirocyclic diketopiperazine alkaloid, namely, 7-O-methylvariecolortide A (1), together with recently reported known compounds variecolortides A-C (2–4), were isolated and identified from the liquid fermentation cultures of Eurotium rubrum, an endophytic fungus that was isolated from the inner tissue of the stems of the mangrove plant Hibiscus tiliaceus. The structures of these compounds were determined by extensive analyses of their spectroscopic data.
