从景天科药用植物垂盆草的全草中分离到13种黄酮类成分, 经鉴定为：苜蓿素（tricin）, 苜蓿甙（tricin－7－glucoside）,木犀草素（luteolin）,木犀草素-7-葡萄糖甙（luteolin－7－glucoside）,甘草素（liquiritigenin）, 甘草甙（liquiritin）, 异甘草素（isoliquiritigenin）, 异甘草甙（isoliquiritin）,异鼠李素-7-葡萄糖甙（isorhamnetin－7－glucoside）, 异鼠李素-3, 7-二葡萄糖甙（isorhamnetin3,7-diglucoside）,柠檬素（limocitrin）, 柠檬素-3-葡萄糖甙（limocitrin－3－glucoside）, 柠檬素-3, 7-二葡萄糖甙（limocitrin－3,7－diglucoside）。

Thirteen flavonoids were isolated from whole herb of Sedum sarmentosum Bunge, which were identified as tricin, tricin-7-glucoside, luteolin, luteolin-7-glucoside, liquiritigenin, liquirtin, isoliquiritigenin, isoliquiritin, isorhamnetin-7-glucoside, isorhamnetin-3, 7-diglucoside, limocitrin, limocitrin-3-glucoside, and limocitrin-3, 7-diglucoside by phsico-chemical constants, specttrospic studies and chemical reactions.
