Enrichment and Purification of Syringin, Eleutheroside E and Isofraxidin from Acanthopanax senticosus by Macroporous Resin

In order to screen a suitable resin for the preparative simultaneous separation and purification of syringin, eleutheroside E and isofraxidin from Acanthopanax senticosus, the adsorption and desorption properties of 17 widely used commercial macroporous resins were evaluated. According to our results, HPD100C, which adsorbs by the molecular tiers model, was the best macroporous resin, offering ...

Isofraxidin, a coumarin component from Acanthopanax senticosus, inhibits matrix metalloproteinase-7 expression and cell invasion of human hepatoma cells.

7-Hydroxy-6,8-dimethoxy-2H-1-benzopyran-2-one (isofraxidin) is a major coumarin component isolated from the stem bark of Acanthopanax senticosus, a widely used Chinese medicinal herb. We investigated isofraxidin in its anti-tumor effects on human hepatoma cell lines HuH-7 and HepG2. Isofraxidin significantly inhibited hepatoma cell invasion, without affecting cell attachment or growth. Expressi...

Preparative Purification of Liriodendrin from Sargentodoxa cuneata by Macroporous Resin

The preparative purification of liriodendrin from Sargentodoxa cuneata using macroporous resin combined with crystallization process was evaluated. The properties of adsorption/desorption of liriodendrin on eight macroporous resins were investigated systematically. X-5 resin was selected as the most suitable medium for liriodendrin purification. The adsorption of liriodendrin on X-5 resin fitte...

Semipreparative separation and determination of eleutheroside E in Acanthopanax giraldii Harms by high-performance liquid chromatography.

A method for the isolation, purification, and determination of eleutheroside E in Acanthopanax giraldii Harms, collected in the Sichuan province (China), is established. The water extraction of A. giraldii Harms is pre-isolated using macroporous adsorption resin (D-101) and a C18 solid-phase extraction cartridge, and the enriched extract is purified to give eleutheroside E (syringaresinol-di-O-...

Synthesis and Production of Sweet-Tasting Protein in E. coli and Purification by Amylose Resin

A sweet water-soluble protein that reminds stable over wide ranges of temperature and pH, Brazzein has various applications. Its tastes like cane sugar but have no calories. However, the extraction of brazzein from its natural source is expensive and not applicable. In this study we used recombinant DNA technology to provide an alternative option for cheaper mass production of brazzein. A brazz...
