摘要

目的/背景:几内亚Lomariopsis guineensis (Underw.)是一种附生攀缘蕨类植物。它广泛分布在非洲，在那里它也被用于传统药物和食物。该植物的化学成分未见文献报道，因此本研究旨在分离该植物的化学成分。方法:采用柱层析法提取乙酸乙酯提取物，并采用核磁共振和质谱法对分离成分进行表征。结果:分离得到3个化合物，鉴定为环蒿醇、叶绿素A和一个新的异黄酮(5,7 -二羟基-4′甲氧基-6,8-二甲基异黄酮)。结论:首次从该植物中分离到3种植物化学物质，其中包括1种新的异黄酮。关键词:大豆异黄酮;Lomariopsis guineensis;脱镁叶绿素;cycloartenol;antitrypanosomal化验

A New Isoflavone from Lomariopsis guineensis (Underw.) Alston

Aim/background: Lomariopsis guineensis (Underw.) Alston is an epiphytic climbing fern. It is widely distributed in Africa where it is also used in traditional medicine and as food. There are no previous reports of any constituents of the plant, hence this study to isolate any phytoconstituents. Method: The ethyl acetate extract of the leaves was subjected to column chromatography and isolated constituents were characterized using nuclear magnetic resonance and mass spectrometry. Results: Three compounds were isolated and identified as cycloartenol, pheophytin A and a new isoflavone (5, 7-dihydroxy-4′ methoxy-6,8-dimethylisoflavone). Conclusion: Three phytochemicals including a new isoflavone are reported from the plant for the first time. Keywords: Isoflavone; Lomariopsis guineensis; pheophytin A; cycloartenol; antitrypanosomal assay
