Identifikacija kemijskih spojeva u listovima biljke Leea indica

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

A new flavonoid diglycoside from <em>Biophytum reinwardtii</em> (Zucc.) Klotzsch. and evaluation of its antioxidant and anticancer activities

880-889A new flavonoid diglycoside namely apigenin-4ʹ,5-O-β-D-diglucoside 1 has been isolated from the whole plant of Biophytum reinwardtii (Zucc.) Klotzsch. and its structure has been elucidated by a combination of spectroscopic (1H, 13C and 2D NMR spectroscopy), mass spectral data and chemical methods. The compound 1 has been evaluated for its antioxidant activities viz., DPPH free radical scavenging activity and modified ferric reducing/antioxidant power (FRAP) assay and anticancer activity viz., MTT assay. The compound 1 has been found to possess significant antioxidant and anticancer activities
