Objective To study the chemical constituents in the roots of Hemerocallis fulva. MethodsCompounds were isolated from the CHCl3and n-butanol fraction of the EtOH extract by repeated column chromatography and their structures were identified by spectral analysis and physicochemical properties. Results From the CHCl3 and n-butanol fraction of the EtOH extract in the roots of H. fulva,ten compounds were isolated and identified as terresoxazine (Ⅰ),11-keto-?-boswellic acid (Ⅱ),hopane-6?,22-diol (Ⅲ),hecogenin (Ⅳ),stigmast-4-en-3?-ol (Ⅴ),stigmast-4-en-3-one (Ⅵ),?-feruloyloxy acid (Ⅶ),(E)-3,4-dihydroxyl cinnamic acid (Ⅷ),(E)-p-methyl cinnamic acid (Ⅸ),and vanillic acid (Ⅹ). Conclusion Compounds Ⅰ-Ⅳ,and Ⅶ are isolated and identified from the plants of Hemerocallis L. for the first time.

AIM: To isolate and identify triterpenes from inflorescence of Cremanthodium potaninii C.Winkl,collected from Qinghai province.METHODS: The triterpenes were isolated by column chromatography and their structures were elucidated through NMR.RESULTS: Seven triterpenes were isolated and identified as ?-amyrin(I),Taraxast-20(30)-ene-3?,16?-diol-3-O-palmitate(II),olean-12-en-3?,16?-diol-3-O-palmitate(III),Olean-12-en-3?,11?,16?-triol-3-palmitate(IV),lup-3?,16?-diol-3-O-palmitate(V),lup-3?,16?,28-triol-3-O-palmitate(VI),16?-hydroxypseudo tarsxasterol-3-O-palmitate(VII).CONCLUSION: All these compounds are obtained from Cremanthodium potaninii C.Winkl for the first time.

OBJECTIVETo study the chemical constituents of Oxytropis microphylla.

METHODThe compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, 13C-NMR).

RESULTEight compounds were isolated and identified as kaempferol (1), baicalein (2), 5-hydroxy-7, 8, 4'-trimethoxyflavone (3), stigmasterol (4), stigmast-4-en-3beta-ol (5), beta-sitosterol (6), lupenol (7), dehydrocostus lactone (8).

CONCLUSIONAll compounds were isolated for the first time from this plant, compounds 2, 3, 5, and 8 were isolated for the first time from this genus.
