องค์ประกอบทางเคมีของรากคนทา (Harrisonia perforata Merr.) / ผกามาส เหล่าทองสาร = Chemical constituents of the roots of harrisonia perforata merr. / Pakamas Lauethongsan
Dried Roots of Harrisonia perforata Merr. were finely crushed and extracted with methyl alcohol, giving a dark red crude. This crude was further extracted with hexanes and chloroform, giving a dark green and a dark red crude respectively. The crudes were separated by column chromatography and quick column chromatography, from which, six compounds were seperated. Determination of structure was done through the physical properties, chemical reactions and spectroscopic evidences. Four identified components were herteropeucenin-7-methyl ether, perforatic acid, mixed steroids of β-sitosterol, stigmasterol and campesterol, and mixed glycosides of β -sitosteryl-3-o-glucopyranoside, stigmasteryl-3-o-glucopyranoside, chloreste l-3-o-glucopyranoside. The other two components were compound 4 (m.p. 220°C), and compound 5 (m.p. 66-68°C). Besides, the present study also reported the identification of the aqueous layer extract, from which the chloride salts, sugars and amino acids were found.
