Chemical constituents of Neolitsea parvigemma and Neolitsea konishii

Twenty-four compounds including three flavonoids, kaempferol-3-O-rhamnoside (1), quercetin-3-O-rhamnoside (2), and taxifolin-3-O-rhamnoside (3); three ferulates, docosanylferulate (4), tetracosanylferulate (5), and hexacosanylferulate (6); two cyclohex-2-en-1-ones, blumenol A (7), and roseoside (8); two sesquiterpenes, zeylanidine (9), and zeylanicine (10); four triterpenes, lupeol (11), lupenone (12), taraxerol (13), and taraxerone (14); one steroid, beta-sitosterol (15); one amide, N-trans-feruloylmethoxytyramine (16); eight alkaloids, roemerine (17), actinodaphnine (18), N-methylactinodaphnine (19), glaucine (20), and oxoglaucine (21), boldine (22), corydine (23) and methoxyannomontine (24) were isolated from Neolitsea parvigemma and N. konishii. These compounds were characterized and identified by physical and spectral evidence. Among them, compounds 1, 2, 3, 4, 5, 6, 7, 8, 13, 14, 16, 20, 21, 23, and 24, were isolated for the first time from this genus. This finding is useful as a basis for chemotaxonomy.
