Lianqiaoxinoside B, a novel caffeoyl phenylethanoid glycoside from Forsythia suspensa.
Chemical investigation of the 70% ethanol extract of the unripe fruits of Forsythia suspensa resulted in the isolation of a novel caffeoyl phenylethanoid glycoside, lianqiaoxinoside B, together with the known compound forsythoside H. The new compound was elucidated to be 1'',2''-[β-(3,4,-dihydroxylphenyl)-α,β-dioxoethanol]-3''-O-caffeoyl-O-α-rhamnopyranosyl-(1→6)-O-β-glucopyranoside by extensiv...
متن کاملUltrasound-assisted extraction of capsaicinoids from peppers.
The development of a rapid, reproducible and simple method of extraction of the majority capsaicinoids (nordihydrocapsaicin, capsaicin, dihydrocapsaicin, homocapsaicin and homodihydrocapsaicin) present in hot peppers by the employment of ultrasound-assisted extraction is reported. The study has covered four possible solvents for the extraction (acetonitrile, methanol, ethanol and water), the op...
متن کاملOptimisation of ultrasound-assisted extraction of phenolic compounds from Flomidoschema parviflora
Background & Aim: Restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are being imposed because of their carcinogecity . Experimental: In this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of Flomideschema parviflorum through response surface methodology by Fulin Ci...

متن کاملOptimization and Comparison of Ultrasound-Assisted Extraction of Estragole from Tarragon Leaves with Hydro-Distillation Method
A comparative study of ultrasound-assisted extraction (UAE) and hydro-distillation was performed for fast extraction of estragole from tarragon (Artemisia dracunculus L.) dried leaves. Several influential parameters of the UAE procedure in the extraction of estragole (type of solvent, extraction cycles, solvent to material ratio, irradiation time and particle size) were investigated an...
