Aphyllin, the first isoferulic acid glycoside and other phenolics from Tamarix aphylla flowers.


PMID 19530447

Abstract

The first glycosylated isoferulic acid, isoferulic acid 3-O-beta-glucopyranoside, together with the new phenolics, tamarixetin 3,3'-di-sodium sulphate and dehydrodigallic acid dimetyl ester have been characterized from a flower extract of Tamarix aphylla. The structures were established on the basis of spectral data. The extract exhibited a distinct radical scavenging effect and to improve the viability of human keratinocytes (HaCaT cells). Also, the known isoferulic acid and ferulic acid which have been determined to be the major components of the investigated extract by HPLC/ESI mass spectrometric screening have been separated, characterized and evaluated as active antioxidants and as cell activity stimulating agents as well.
