摘　　要：Objective To study the chemical constituents of Hedyotis tenelliflora.Methods The compounds were isolated by chromatographic separation technology.The structures were identified on the basis of chemical and spectral data.Results Four iridoid glycosides were isolated from the whole plant of H.tenelliflora.On the basis of the chemical and spectral methods,their structures were elucidated as teneoside C(1),harpagoside(2),harpagide(3),and asperulosidic acid(4).Conclusion Compound 1 is a new compound,and compounds 2 and 3 are isolated from H.tenelliflora for the first time.Objective To study the chemical constituents of Hedyotis tenelliflora.Methods The compounds were isolated by chromatographic separation technology.The structures were identified on the basis of chemical and spectral data.Results Four iridoid glycosides were isolated from the whole plant of H.tenelliflora.On the basis of the chemical and spectral methods,their structures were elucidated as teneoside C(1),harpagoside(2),harpagide(3),and asperulosidic acid(4).Conclusion Compound 1 is a new compound,and compounds 2 and 3 are isolated from H.tenelliflora for the first time.
