진달래 줄기의 세포독성 성분

초록

compounds were isolated from the n-BuOH soluble fraction of stem of Rhododendron mucronulatum ascytotoxic principles against brine shrimp lethality test. On the basis of spectral data, seven compounds were identified as ()-cat-echin (1), (+)-epicatechin (2), taxifolin (3), scopoletin (4), quercetin (5), taxifolin-3-O-α-L- arabinopyranoside (6), and astragalin(7). Among tested compounds, taxifolin-3-O-α-L-arabinopyranoside (6) exhibited potent activity with LC50 value at 4.6g/ml.Key wordsCytotoxiciy, Rhododendron mucronulatum, brine shrimp lethality test, taxifolin-3-O-α-L-arabinopyranosideBrine shrimp lethality test. cytotoxicity,1,2)pesticideresidues3)
