摘要
Aim Isolation and structural elucidation of the constituents from the dried flower buds of Magnolia biondii Pamp. Methods Column chromatography and TLC were used to isolate chemical constituents. Spectroscopic methods were employed for structural elucidation. Results One benzo furanoid neolignan （licarin B） and two bisepoxy lignans （magnolin, fargesin） were isolated and identified. Conclusion Licarin B is the first reported benzofuranoid lignan from the family Magnoliaceae.
目的研究望春花MagnoliabiondiiPamp花蕾中的化学成分。方法采用色谱技术进行分离纯化,根据理化性质和现代波谱技术进行结构鉴定。结果从望春花的花蕾乙醇提取物中分离鉴定出1个苯并呋喃类新木脂素和2个已知木脂素,分别鉴定为利卡灵B(licarinB)1;木兰脂素(magnolin)2;辛夷脂素(fargesin)3。结论木兰属植物中木脂素多为双环氧型,苯并呋喃类新木脂素licarinB是首次从木兰科植物中分得。
