Description
The chloroform-soluble fraction in a methanol extract from mature seeds of Sophora tomentosa L.was subjected to chromatographic separation and purification to give two flavonoids (4 and 5), two isoflavonoids (3 and 6), one lupin alkaloid (1) and one polyphenol (2), respectively. These compounds were identified as 7,4’-dihydroxy- 3’-methoxyflavone (4, geraldone), 7,3’-dihydroxy-4’-methoxyflavone (5, farnisin), 7,3’-dihydroxy-5’-methoxyisoflavone (3), 7,4’-dihydroxy- 3’-methoxyisoflavone (6), N-methylcytisine (1) and methyl 3,4- dihydroxybenzoate (2, methyl protocatechuate), respectively, by spectroscopic methods.
