of the antiviral active fraction of the roots of Platycodon grandiflorum leads to the isolation of three new triterpenoid saponins, platycosides G1–G3 (1–3), as well as two known saponins, platycodin D3 (4), and platycoside E (5). The structures of the new compounds were elucidated on the basis of their spectral data and chemical evidences. The isolated saponins were tested for their antiviral activities
生物测定指导的根部的抗病毒活性级分的分馏桔梗通向三个新的三萜皂甙,platycosides G1-G3(的隔离1 - 3),以及两个公知的皂甙,桔梗D3(4),和platycoside E(5)。根据新化合物的光谱数据和化学证据对它们的结构进行了阐明。测试了分离出的皂苷对呼吸道合胞病毒(RSV),单纯疱疹1型病毒(HSV-1)和A型流感病毒(Flu A)的抗病毒活性。化合物4显示弱的抗RSV活性。
