cytellin and phellopterin

To investigate the chemical constituents of Toddalia asiatica.. The compounds were isolated and pu- rified by column chromatography and their structures were identified on the basis of physicochemical properties and spectral data analysis.. Sixteen compounds were isolated and identified as zanthocadinanine A(1), pimpinellin(2), isopimpinellin(3), phellopterin (4), armottianamide(5), chelerythrine(6), nitidine(7), chlorogenic acid (8), toddalolactone (9), protopine(10), skimmianine(11), dictamine(12), toddalenone(13), beta-sitosterol(14), bergapten(15) and 8-hydroxy-6-methoxycoumarin(16).. Compound 1 and 16 are isolated from Toddalia genus for the first time.

To study the chemical constituents from the seeds of Notopterygium franchetii.. Ethanol extracts of seeds N. franchetii were separated and purified by such methods as normal and reversed phase column chromatographies and thin-layer chromatography and structurally elucidated by MS and NMR evidences.. Twenty nine compounds were separated, they were isoimperatorin (1), [3-sitosterol (2), phellopterin (3), bergapten (4), N-tetra, hexa, octacosanoylanthranilic acid (5-7), daucosterol (8), oxypeucedanin hydrate (9), umbelliferone (10), demethylfuropinnarin (11), (2S, 3S, 4R, 8E)-2-[(2'R)- 2'-hydroxydoco, trico, tetraco, entaco, hexaco sanosylamino] -octadecene-1, 3, 4-triol (12-16), (-)-oxypeucedanin (17), diosmetin (18), bergaptol-O-beta-D-glucopyranoside (19), nodakenin (20), 1'-O-beta-D-glucopyranosyl-(2R, 3S)-3-hydroxynodakenetin (21), uracil (22), decuroside V (23), 8-O-beta-D-glucopyranosyl-5-hydroxypsoralen (24), 8-O-beta-D-glucopyranosyl-5-methoxylpsoralen (25), diosmin (26), alaschanioside C (27), kynurenic acid (28) and mannitol (29).. All of these compounds were separated from the seeds of N. franchetii for the first time. Of them, 18, 22, 26 and 29 were firstly obtained from genus Notopterygium.
