摘要

Total anthocyanins of sweet pea (Lathyrus odoratus L.) flowers of different colour pale red, dark red, and dark pink were determined. The total anthocyanins were 0.026, 0.131 and 0.338 gm/100 gm fresh weight, respectively. Four anthocyanins were isolated and identified from dark pink flowers (cyanidin-3- glucoside, cyanidin 3,5 gluco-galactoside, malvidin 3,5 diglucoside and delphinidin 3,5 diglucoside), and two anthocyanins from pale red and dark red flowers (pelargonidin 3,5 gluco-xyloside and cyanidin 3,5 gluco-galactoside). Pale red and dark red types contained similar anthocyanins and cyanidin 3,5 gluco-galactoside was common in the three colours. GC/MS analysis of the alcoholic concrete extract of the sweet pea flowers revealed the presence of 30 components, 98 % of the constituents were identified. The results demonstrated that the major components were palmitic acid constituted (52.303 %), linoleic acid (9.655 %), methyl linolenate (6.683 %), uncosanoic acid methyl esters (6.644 %) and heptadecanoic acid (3.085 %). Antimicrobial activity of total, isolated anthocyanins and the alcoholic concrete of sweet pea was tested. The total anthocyanins of pale red type was the most potent one as anti-bacterial, anti-yeast, anti-fungal followed by the total anthocyanins of dark red type and dark pink type. The total anthocyanins of the three types were more potent than their isolated compounds. The alcohol extract of the concrete showed the lowest effect as anti-bacterial and yeast but showed the highest effect as anti-fungal.
