Transrutinosylation of tyrosol by flower buds of Sophora japonica

Dried flower buds of Japanese sophora (Sophora japonica) comprising rutinosidase activity were tested in rutinosylation of tyrosol via transglycosylation process from rutin. Optimal conditions for transrutinosylation of tyrosol were 49 mM rutin and 290 mM

New assay of α-l-rhamnosidase

Abstract: Free rutinose was prepared by enzymatic hydrolysis of rutin using defatted seed meal from tartary buckwheat. This disaccharide was used as substrate in spectrophotometric assay of α-l-rhamnosidase. The assay is based on hydrolysis of rutinose and subsequent determination of released glucose by a standard glucose oxidase assay kit. The method is easy to perform and requires no expensive equipment. The assay was applied in α-l-rhamnosidase estimation in ten commercial enzyme preparations and compared with standard assay on chromogenic substrate.

Dracopalmaside, a New Flavonoid from Dracocephalum palmatum

Phytochemical studies of the aerial part of Dracocephalum palmatum (Lamiaceae) isolated the new flavonoid dracopalmaside that was identified based on UV, MS, and NMR spectral data as luteolin-7,4′-di-O-α -Lrhamnopyranosyl-(1→6)-β-D-glucopyranoside (luteolin-7,4′-di-O-rutinoside) and the two known compounds cynarotriside and luteolin-7,4′-di-O-glucoside.
