| Abstract: |
| 【Objective】The study explored the bioactive chemical constituents in the whole Streptocaulon griffithii Hook.【Method】The chemical constituents of the whole S.griffithii Hook were studied with various materials isolation and identification technologies such as silica gel,RP 18,Sephadex LH-20.【Result】The results were as follows:7 compounds were isolated from the whole S.griffithii Hook.Their structure identifications were:(24S)-24-ethylcholesta-3β,5α,6β-triol,7α-hydroxysitosterol-3-O-β-glucoside,daucosterol,β-stiosterol,isovanillin,4-hydroxy-3,5-dimethoxybenzaldehyde and arturmeron on the basis of analysis and verification.【Conclusion】The compounds 1,2,5,6 and 7 were firstly isolated from the whole S.griffithii Hook in the 7 compounds. |
