        碳谱( C-NMR)数据进行结构鉴定。分别以阿卡波糖、阿维菌素为阳性对照,采用对硝基苯基-α-D-吡喃葡萄糖苷(PNPG)法和贝
        曼漏斗法分别对上述化合物进行体外α-葡萄糖苷酶抑制活性和全齿复活线虫致死活性考察。结果:从黄皮种子中共分离鉴定出7
        个香豆素类化合物,分别为7-羟基香豆素(Ⅰ)、黄皮呋喃香豆精(Ⅱ)、Lansiumarin-C(Ⅲ)、Claucoumarin A(Ⅳ)、Clausenalansimin
        A(Ⅴ)、(E,E)-8-(7-羟基-3,7-二甲基-2,5-二烯基)补骨脂(Ⅵ)、Dihydroindicolactone(Ⅶ)。在质量浓度为0.25 mg/mL时,化合物
        Ⅰ、Ⅲ、Ⅴ的α-葡萄糖苷酶抑制率分别为(32.4±1.9)%、(37.1±6.0)%、(39.5±1.1)%;在质量浓度为2.5 mg/mL时,化合物Ⅰ、Ⅳ的
        线虫校正死亡率分别为50.5%、47.9%。结论:香豆素类化合物Ⅰ、Ⅲ、Ⅴ具有α-葡萄糖苷酶抑制活性,化合物Ⅰ、Ⅳ具有全齿复活
        线虫致死活性。其中,化合物Ⅲ、Ⅴ的α-葡萄糖苷酶抑制活性、化合物Ⅳ的全齿复活线虫致死活性均为首次发现。

        ABSTRACT    OBJECTIVE:To isolate and identify the coumarins from the seeds of Clausena lansium,and to study their
        inhibitory activity of α-glucosidase and nematicidal activity against Panagrellus redivivus. METHODS:Column chromatography,
        reversed phase silica gel column chromatography and HPLC method were used to separate and purify the coumarins from the seeds
                                                                                          1
        of C. lansium. The structures of compounds were identified according to physicochemical properties, H-NMR and  13 C-NMR
        spectral data. Using acarbose and avermectin as positive control,PNPG and Berman funnel methods were used to investigate the
        α-glucosidase inhibitory activity and nematicidal activity against P. redivivus,respectively. RESULTS:Seven coumarins compounds
        were isolated from the seeds of C. lansium,and were identified as 7-hydroxy-1-benzopiran-2-one (Ⅰ),Wampetin (Ⅱ),
        Lansiumarin-C(Ⅲ),Claucoumarin A(Ⅳ),Clausenalansimin A(Ⅴ),(E,E)-8-(7-hydroxy-3,7-dimethylocta-2,5-dienyloxy)
        psoralen(Ⅵ),Dihydroindicolactone(Ⅶ). Under 0.25 mg/mL,the α-glucosidase inhibitory rates of compounds Ⅰ,Ⅲ,Ⅴ were
        (32.4±1.9)%,(37.1±6.0)%,(39.5±1.1)%,respectively. Under 2.5 mg/mL,corrected mortality of compounds Ⅰ,Ⅳwere
        50.5% and 47.9% . CONCLUSIONS:Compounds Ⅰ ,Ⅲ ,Ⅴ show α-glucosidase inhibitory activity,and compounds Ⅰ ,Ⅳ
                                                            display nematicidal activity against P. redivivus. α-Glucosidase
