目的研究落花生枝叶的化学成分.方法采用硅胶柱色谱、反相硅胶柱色谱、Sephadex LH-20柱色谱等方法分离纯化,根据化合物的波谱数据鉴定结构.结果从落花生枝叶水提取物中分离鉴定了17个化合物,本实验主要研究从正丁醇萃取部分分离得到的4个降倍半萜类化合物:落花生苷A(arachiside A,Ⅰ)、狗筋蔓内酯(cu-cubalactone,Ⅱ)、长春花苷(roseoside,Ⅲ)、柑橘苷A(citroside A,Ⅳ).结论化合物Ⅰ为新的化合物,命名为落花生苷A(arachiside A),化合物Ⅱ~Ⅳ为首次从该属植物中分离得到.

Objective To investigate the chemical constituents in the stems and leaves of Arachis hypogaea.Methods The isolated compounds Ⅰ-Ⅳ were obtained by the combination of silica gel,ODS-18,and Sephadex LH-20 column chromatographies.Structural elucidation was conducted by the moedrn spectral method.Results Seventeen compounds were isolated and identified from the water extraction,and there were four norsesquiter-pene compounds from butanol extraction.They are arachiside A(Ⅰ),cucubalactone(Ⅱ),roseoside(Ⅲ),and citroside A(Ⅳ).Conclu-sion Compound Ⅰis a new compound named arachiside A and compounds Ⅱ-Ⅳ are isolated from the plants of Arachis Linn.for the first time.
