RESUMEN
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.

Three new serratane-type epoxytriterpenoids were isolated from the whole plant of Huperzia serrata. The structures of these new compounds were characterized as 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21 beta-ol (1), 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol (2), and 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol-3 beta-O-acetate (3), respectively, on the basis of spectral data and for 1 by single-crystal X-ray 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.
