[Chemical composition of fructus Liquidambaris--lulutong].Yao Xue Xue Bao. 2002 Apr; 37(4):263-6.YX
To study the chemical composition in the fruits of Liquidambar formana Hance.
Various column chromatographic techniques were used to separate and purify the constituents. Their physical and chemical properties and spectral data were measured for structural elucidation.
Eleven compounds were isolated and identified as beta-sitosterol (1), 3-oxo-11 alpha, 12 alpha-epoxyleanan-28, 13 beta-olide (2), 3-oxo-12 alpha-hydroxy-oleanan-28, 13 beta-olide (3), 3 alpha-acetyloxy-25-hydroxyolean-12-en-28-oic acid (4), oleanolic acid (5), ursolic acid (6), daucosterol (7), betulonic acid (8), gallic acid (9), nonacosane (10) and n-triacontanoic acid (11).
Among the isolated constituents, compound 4 is new compound, compound 3 is firstly isolated from the natural product and compound 5, 6, 7, 9, 10 and 11 are isolated from LuLuTong for the first time.
