Identification of chemical compounds from the leaves of Leea indica

Abstract

Twenty-three known chemical compounds were identified in the leaves of Leea indica (Burm. f.) Merr. (Leeaceae) by GC-MS analysis, spectroscopic techniques and co-TLC with authentic samples. The identified compounds include eleven hydrocarbons, phthalic acid, palmitic acid, 1-eicosanol, solanesol, farnesol, three phthalic acid esters, gallic acid, lupeol, β-sitosterol and ursolic acid. Gallic acid was isolated as n-butylgallate and identified by co-TLC. This seems to be the first report of the presence of gallic acid in the leaves of L. indica.U listovima biljke Leea indica (Burm. f.) Merr. (Leeaceae) identificirano je 23 sastojka koristeći GC-MS analizu, spektroskopske metode i TLC. Među identificiranim spojevima su 11 ugljikovodika, ftalna i palmitinska kiselina, 1-eikozanol, solanesol, farnesol, tri estera ftalne kiseline, galna kiselina, lupeol, β-sitosterol i urson. Galna kiselina je izolirana kao n-butilgalat i identificirana pomoću TLC. Čini se da je ovo prvo izvješće o prisutnosti galne kiseline u listovima L. indica
