Syringin

Salicylic acid enhances jaceosidin and syringin production in cell cultures of Saussurea medusa.

A diverse group of chemical compounds isolated from Acanthopanax species was named "eleutherosides" The group of eleutherosides consists of eleutherosides A (daucosterol), B (syringin), [B.sub.1] (isofraxidin-7-O-glucoside), [B.sub.2], [B.sub.3], [B.sub.4] (sesamin), C (methyl-[alpha]-D-galactoside), D, E (syringaresinol-di-O-[beta]-D-glucoside), [E.sub.1] (syringaresinol-O-[beta]-D-glucoside), [E.sub.2] (episyringaresinol 4"-O-[beta]-D-glucoside), F, G, I, K, L, and M (hederasaponin B) [2-5].

Chromatographic purification of these fraction led to the isolation of a mixture of two compounds 2, 3 isolated for the first time from natural source and five known compounds 1, 4-7 which were characterized as 11-hydroxymustakone (2), N-methyl-2-pyrrolidone (3), N-formylannonain (1), cordifolioside A (4), magnoflorine (5), tinocordiside (6), syringin (7) by nuclear magnetic resonance (NMR) and mass spectrometry (MS) and comparing the spectral data with reported one.

Optimization of Extraction Technology of Syringin and Glycosides E from Acanthopanax Stem and Root.

According to these studies syringin protects against radiation, reduces radiation induced leucopenia and is immunostimulatory.

Therefore, UAE has been widely used in the literature for the extraction of biologically active compounds, including the extraction of geniposide from Gardenia jasminoides [16], extraction of syringin from Ilex rotunda [17].

Using animal models, bioassay-guided fractionation of various extracts of plant adaptogens have shown that the active principles are mainly phenylpropane and phenylethane derivatives including salidroside, rosavin, syringin, triandrin, tyrosol, etc.
