Twenty-eight compounds including seven alkaloids, (+)-3-chloro-N-formylnorn antenine (1), (+)-N- formylnornantenine (2), (+)-boldine (3), (+)-norboldin e (4), (-)-norboldine (5), lycicamine (6), and tetrahydroberberine (7); fou r flavonoids, kaempferol (8), kaempferol-3-O-arabinoside (9), quercetin (10 ), and quercetin-3-O-rhamnoside (11); one butanolide, akolactone A (12); on e p-quinone, 2,6-dimethoxy-p-quinone (13); one cyclohex-2-en-1-one, blumeno l A (14); six benzenoids, methylparaben (15), p-hydroxybenzoic acid (16), v anillic acid (17), syringic acid (18), 3,4,5-trimethoxybenzoic acid (19), a nd 3-(3,4-dihydroxyphenyl) propionic acid (20); one diterpene, phytol (21); one triterpene, squalene (22), six steroids, beta-sitosterol (23), beta-si tostenone (24), stigmasta-4,22-dien-3-one (25), 6 beta-hydroxy-beta-sitoste none (26), 6 beta-hydroxystigmasterone (27), and beta-sitosteryl-D-glucosid e (28) were isolated from the aerial part of Lindera glauca. These compound s were characterized and identified by physical and spectral method. All co mpounds were isolated for the first ti me from th is plant. Among th em, ()-3-chloro-N-formylnornantenine (1) is a new one.
