ENHANCED COMPOUND-ENZYMES- -ASSISTED EXTRACTION OF POLYSACCHARIDES FROM Cornus officinalis
The process of ultrasonic-enhanced compound-enzymes-assisted extraction of polysaccharides from the fruit of Cornus officinalis was optimized by response surface methodology (RSM). The influence of three different factors on the yield of C. officinalis polysaccharides (COP) was studied. The results showed that the optimal conditions were extraction temperature 49.6 °C, ultrasound time 40.41 min...
متن کاملVariation in the composition of the essential oil of Valeriana officinalis L. roots from Estonia
The volatile constituents from roots of Valeriana officinalis L. were investigated using GC and GC/MS methods. Valerianae radix samples were obtained from retail pharmacies or cultivated in Estonia. The roots of five V. officinalis samples yielded 0.28–1.16% essential oil in the cut drug, which usually corresponded (four samples) to the European Pharmacopeia standard (0.3%). The basic oil compo...
متن کاملUltrasound-assisted extraction of polysaccharides from mulberry leaves.
Ultrasound-assisted extraction (UAE) of polysaccharides from mulberry leaves was studied. The effects of four factors on the yield of polysaccharides were investigated. The results showed that optimum conditions were extraction power of 60W, extraction temperature of 60°C, extraction time of 20min and ratio of water to raw material of 15:1 (ml/g). The three different methods (UAE, MAE and CSE) ...

متن کاملEssential Oils from Hairy Root Cultures and Field Cultivated Roots of Valerian (Valeriana sisymbriifolium)
Background: Plant cell cultivations are considered as an alternative to agricultural processes for producing valuable phytochemicals (secondary metabolites). The use of plant cell cultures has overcome several inconveniences for the production of secondary metabolites. Objective: The essential oils isolated from roots of 24-month-old field grown valerian (Valeriana sisymbriifolium) and hairy r...
