Separation of phenylpropanoid glycosides from a Chinese herb by HSCCC.
An effective high-speed counter-current chromatography method was established for the preparative isolation and purification of two phenylpropanoid glycosides from the Tibetan medicinal plant Pedicularis longiflora Rudolph. var. tubiformis (Klotz). Tsoong. With a two-phase solvent system composed of chloroform-n-butanol-methanol-water (4:3:4:5, v/v), 40 mg of an extract of Pedicularis longiflor...
متن کاملPhenylpropanoid glycosides from Scrophularia ningpoensis.
Three phenylpropanoid glycosides named ningposides A (3-O-acetyl-2-O-feruloyl-alpha-L-rhamnopyranose), B (4-O-acetyl-2-O-feruloyl-alpha-L-rhamnopyranose) and C (3-O-acetyl-2-O-p-hydroxycinnamoyl-alpha-L-rhamnopyranose) along with the known compounds sibirioside A, cistanoside D, angoroside C, acteoside, decaffeoylacteoside and cistanoside F were obtained from the roots of Scrophularia ningpoensis.
متن کاملLignan and phenylpropanoid glycosides from Fernandoa adenophylla.
From the leaves and branches of Fernandoa adenophylla, a lignan glycoside (fernandoside) and a phenylpropanoid glycoside (2"-O-beta-apiosylverbascoside) were isolated together with 12 known compounds. The structural elucidations were based on analyses of physical and spectroscopic data.
متن کاملBioactive phenylpropanoid glycosides from Tabebuia avellanedae.
Three novel phenylpropanoid glycosides 2, 5, 6 were isolated from water extract of Tabebuia avellanedae, together with three known phenylpropanoid glycosides 1, 3, 4. All compounds were identified on the basis of spectroscopic analysis and chemical methods and, for known compounds, by comparison with published data. All isolated compounds showed strong antioxidant activity in the DPPH assay, an...
متن کاملTyrosinase inhibitory properties of phenylpropanoid glycosides and flavonoids from Teucrium polium L. var. gnaphalodes
Objective(s): In food industry, the inhibition of tyrosinase is very important, because this enzyme catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which contribute in undesirable color and taste of fruits and vegetables. Teucrium polium L. var. gnaphalodes (Lamiaceae), a wild-growing flowering plant that has many applications in food preparations and...
