Salt stress enhancement of antioxidant and antiviral efficiency of Spirulina platensis

Cultivation of Spirulina platensis under salt stress conditions (0.02 M as control), 0.04 and 0.08 M NaCl led to a remarkable alteration of algal metabolism as well as an enhancement or induction of biologically active compounds. Concerning algal growth, salt stress caused a decrease in dry weight, chlorophyll a content as well as certain xanthophylls (neoxanthin and violaxanthin) while β-carotene...

Extraction, characterization and antitumor effect of the polysaccharides from star anise (Illicium verum Hook. f.)

Polysaccharides production from star anise was carried out. The effects of extraction temperature, time, ratio of water to raw material and number of extraction were optimized by using an orthogonal L9(3)4 test design. The optimum extraction conditions were determined as follows: extraction temperature 100°C, time 4 h, number of cycle 2 and ratio of water to raw material at 11. Under optimized conditions, the...

Hydrolysis of genistin and daidzin by a β-glucosidase purified from Lentinula edodes

We had studied the purification and characterization of β-glucosidase from Lentinula edodes, and its activity of hydrolyzing genistin and daidzin. The beta-glucosidase was extracted from an edible mushrooms L. edodes fruiting body and concentrated 26.5-fold by (NH4)2SO4 precipitation, followed by CM-Sephadex C-50 and Sephacryl S-300 HR chromatography. The purified enzyme showed a single 66 kd...

Comparative study of essential oil composition of leaves and rhizomes of Alpinia conchigera Griff. at different post- harvest drying periods

Essential oils from the leaves and rhizomes of Alpinia conchigera Griff. dried for different times (0 (fresh), 1, 2, 3 and 7 days of drying, respectively) were isolated using hydrodistillation. The chemical composition of oils was analyzed by using GC and GC-MS. The identified components constituted 95.06, 94.51, 94.64 and 91.60% of the leaf oil and 47.71, 64.19, 49.96, 94.47 and 91.56% of the rhizome oil...

Authentication of Taxillus chinensis using DNA barcoding technique

The purpose of this study is to evaluate the five candidate DNA barcodes of rbcL,matK, psbA-trnH, ITS and ITS2 in order to distinguish Taxillus chinensis from adulterants. Of the five barcodes, the amplification and sequencing efficiencies ofrbcL and trnH-psbA were 100%. Meanwhile, the efficiency of matK, ITS and ITS2 regions was very low due to failure in PCR amplification...
