To study the chemical constituents from Corallodiscus kingianus.
The column chromatographic techniques were applied to isolate constituents. A combination of ESI-MS and NMR spectroscopy was used to identify structures.
Six compounds were isolated from the acetone extract of this plant, and the structures of them have been identified as castanopsol (1) , 3beta-hydroxy-9 (11), 12-oleanadien-28-oic acid (2), 2,3,7-trihydroxy-6-oxo-1,3,5 (10), 7-tetraene-24-nor-frie-delane-29-oic acid methylester (3), 3-epicyclomusalenol (4), palmitinic acid (5) and stearic acid (6).
Compounds 1-6 were isolated for the first time from Gesneriaceae.
研究长果石蝴蝶的化学成分。
采用柱色谱技术分离化合物。结合电喷雾电离质谱（ESI-MS）和核磁共振波谱（NMR）进行结构鉴定。
从该植物的丙酮提取物中分离得到6个化合物，其结构分别鉴定为栲皮醇（1）、3β-羟基-9（11），12-齐墩果二烯-28-酸（2）、2,3,7-三羟基-6-氧代-1,3,5（10），7-四烯-24-降-羊毛甾烷-29-酸甲酯（3）、3-表环木栓醇（4）、棕榈酸（5）和硬脂酸（6）。
化合物1-6为首次从苦苣苔科植物中分离得到。
