ABSTRACT
OBJECTIVE: To study the chemical constituents of the root of Paeonia sinjiangensis. METHOD: The constituents were isolated by silica column chromatography, and their structures were identified on the basis of spectral analysis and their physical-chemical constants. RESULT: Five compounds, paeoniflorin( I ), albiflorin (II), lactiflorin(III), daucosterol(IV), sucrose (V), were obtained. CONCLUSION: All of the compounds were obtained from this plant for the first time.

Sixteen serratane-type triterpenoids including three new compounds, 14beta,15beta-epoxyserratan-3beta,21beta,29-triol (1), serrat-14-en-3beta,21beta,29-triol (2) and serrat-14-en-3alpha,21beta,24,29-tetraol (3), were isolated from the whole plant of Huperzia serrata (Thunb) Trev. The structures of these new compounds (1-3) were elucidated on the basis of spectral analysis.

Two new Lycopodium alkaloids, miyoshianines A and B, together with five known alkaloids, lycopodine, lycodoline, 12-epilycodoline, clavolonine, and flabelliformine, were isolated from Huperzia miyoshiana (Makino) Ching (Huperziaceae). Their structures were determined by means of spectroscopic techniques.
