The ethanol extract of the flowers of Trollius ledebouri yielded four flavone C-glycosides, 2"-O-vanilloylvitexin, 2"-O-feruloylorientin, 2"-O-b-L-galactopyranosylvitexin, and 2"-O-b-L-alactopyranosylorientin, along with known compounds, 6"-O-acetylorientin, 2"-O-(4"-hydroxybenzoyl) vitexin, vitexin, and orientin. Their structures were elucidated by means of UV, IR, MS and NMR spectroscopic analyses.

o new cycloartane triterpene glycosides and a new alkaloid, soulieosides D and E, and soulieotine (1⎯3), and their structures were elucidated on the basis of extensive NMR spectral experiments and chemical methods as (20S∗, 22R∗, 23S∗, 24R∗)-16:23;22:25-diepoxy-3β,24-dihydroxy-23-methoxy-9,19- cyclolanostane-3-O-β-D-(4-acetyl)xylopyranoside (1), (20S∗,22R∗,23S∗,24R∗)-16β:23;22:25-diepoxy-3β,23,24-trihydroxy-9,19-cyclolanostane-3-O-β-D-(3-acet yl)xylopyranoside (2), E-3-(3'-methyl-2'-butenylidene)-6-methoxy-2-indolinone (3).

Five new lanostane-type triterpenes, named fomefficinic acid A-E (1-5), were isolated from the dried sclerotium of Fomes officinalis, respectively. Their structures were established as 24-methylene-3-oxo-lanost-8-en-21-oic acid (1), 3a,15a-dihydroxy-24-methylene-lanosta-7,9(11)-dien-21-oic acid (2), 3a,15a-dihydroxy-24-methylene-lanost-8-en-21-oic acid (3), 15a-hydroxy-3-oxo-24-methylenelanost-8-en-21-oic acid (4), 15a-acetoxy-3-oxo-24-methylenelanosta-7,9(11)-dien-21-oic acid (5), by spectral analysis and chemical methods as well as comparison with known compounds.

从牛蒡（Arction Lappa L.）子乙醚和丙酮提取物中。经硅腔柱层析，低压柱层折和制备性薄层层析分离到一个甾体化合物，胡萝甙（dauosterol, I）和四个已知本脂索：牛蒡子甙元（arctrgenin. II）、牛蒡子甙（arctiin，III）、罗汉橙脂素（matairesinol. IV）和牛蒡酚F（1appaol F, V2）。一个新木脂素，命名为新牛蒡索乙（heartrctin B, VI）。根据光谱（UV, IR, H-NMR, 13C-NMR, DEPT, 2D-NMR和MS）分析，推定了其化学结构为式VI。

原伊鲁烷（Protoilludane）型倍半萜芳香酸酯类化合物是近十年来自人工发酵的真菌培养的菌丝中分离得到的一类新型天然产物。作者等自蜜环菌（Armillaria mellea）菌丝体中分离得到17个该类型化合物，研究这些新化合物的化学结构，对其全去偶碳谱、偏共振谱或INEPT谱、“C-IH COSY谱和远程”C, -1H COSY谱详细地进行分析研究，指出每个化合物各碳的归属，讨论了其碳谱的特征，将其应用于有关化合物的结构测定。
