title: HPLC analysis and NMR identification of homoisoflavonoids and stilbenoids from the inter-bulb surfaces of Scilla nervosa.
abstract: The yellow inter-bulb deposits from Scilla nervosa were analyzed by HPLC and found to contain 19 major components. Twelve of the 19 were identified by comparison of R(t) values with those of authentic homoisoflavonoids and stilbenoids, co-elution and by preparative isolation followed by NMR and MS analyses. Of these, two homoisoflavonoids, 3-(4-hydroxyoxybenzyl)-5,7-dimethoxy-6-hydroxychroman-4-one and 3-(4-methoxybenzyl)-6,7-dimethoxy-5-hydroxychroman-4-one are new.
