The Constituents of Lindera Glauca

Twenty‐eight compounds including seven alkaloids, (+)‐3‐chloro‐ N ‐formylnornantenine ( 1 ), ( +)‐N‐ formylnornantenine ( 2 ), (+)‐boldine ( 3 ), (+)‐norboldine ( 4 ), (‐)‐norboldine ( 5 ), lycicamine ( 6 ), and tetrahydroberberine ( 7 ); four flavonoids, kaempferol ( 8 ), kaempferol‐3‐ O ‐arabinoside ( 9 ), quercetin ( 10 ), and quercetin‐3‐ O ‐rhamnoside ( 11 ); one butanolide, akolactone A ( 12 ); one p ‐quinone, 2,6‐dimethoxy‐ p ‐quinone ( 13 ); one cyclohex‐2‐en‐1‐one, blumenol A ( 14 ); six benzenoids, methylparaben ( 15 ), p‐ hydroxybenzoic acid ( 16 ), vanillic acid ( 17 ), syringic acid ( 18 ), 3,4,5‐trimethoxybenzoic acid ( 19 ), and 3‐(3,4‐dihydroxyphenyl) propionic acid ( 20 ); one diterpene, phytol ( 21 ); one triterpene, squalene ( 22 ); six steroids, (3‐sitosterol ( 23 ), β‐sitostenone ( 24 ), stigmasta‐4,22‐dien‐3‐one ( 25 ), 6β‐hydroxy‐β‐sitostenone ( 26 ), 6β‐hydroxystigmasterone ( 27 ), and β‐sitosteryl‐D‐glucoside ( 28 ) were isolated from the aerial part of Lindera glauca . These compounds were characterized and identified by physical and spectral method. All compounds were isolated for the first time from this plant. Among them, (+)‐3‐chloro‐ N ‐formylnornantenine ( 1 ) is a new one.
