et al.

Abstract: -This study investigates the change of chemical components, antioxidant and antimutagenic activity in Glycyrrhiza uralensis Fischer stems and leaves (GU) by the various processing methods, as follows: fresh (GU-1), dried under the shade (GU-2), blanched (GU-3), roasted 3 times (GU-4), roasted 4 times (GU-5). The components have been identified and quantified through the use of gas chromatograph-mass spectrometry (GC-MS). At results, cis-1,3-dimethyl-2-methylenecyclohexaneat at 19.7 min and n-hexadecanoic acid … Show more

Abstract:In order to find new functional materials for the cosmetics application, we investigated anti-inflammatory and whitening effects of the Protaetia brevitarsis seulensis (P. brevitarsis) extracts, which were prepared by the various oriental conversion methods, as follows; fresh, roasted one time, roasted two times, roasted three times, and steamed. 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities of the various solvent extracts (80% ethanol, 50% ethanol, ethyl acetate, hexane) of P. brevitarsis extracts were 85.5, 22.4, 37.0 and 19.4% respectively. The 80% ethanol

-Glycyrrhiza uralensis Fischer is one of the most commonly used herbs. Recently, the stem and leave of the plant have been interested in physiological activities because the aerial parts have been thrown away. Finding out cultivation method of Glycyrrhiza uralensis Fischer to improve chemical ingredients and biological activities has been tried these days. In this study, different wavelengths of light emitting diode (LED) were used for a cultivation of Glycyrrhiza uralensis Fischer. Antioxidant activities and inhibitory effect on mutagenecity of samples were evaluated. The stem and leave cultivated under blue light (BL-0) showed the strongest antioxidant activities of 3.02 ± 0.13 ㎍/㎖ (EC50) and 2.18 ± 0.18 ㎍/㎖ (EC50) in DPPH and ABTS radical scavenging test, respectively. Total phenolic content of BL-0 was 2.93 ± 0.11 g/100 g, the highest value between cultivation conditions. However, antioxidant activities of the stem and leave cultivated under red light were the weakest between samples. All of the stem and leave used in this study showed inhibitory effect on mutagenecity of 1-nitropyrene. BL-0 showed stronger inhibitory effects on mutagenicity of Trp-P-1, Trp-P-2, and AFB1 than samples cultivated under other conditions. Only on mutagenecity of 2-aminoanthracene, the stem and leave cultivated at 1 m apart from red light (RL-1) showed the strongest inhibitory effect. These results indicate that blue LED might be the most effective condition for improvement of physiological activities for the aerial parts of Glycyrrhiza uralensis Fischer in cultivation. The components were identified with GC/MS. Cytidine was detected only in RL-1 at 25 min of retention time and 2-bromotrimethylene glycol was detected only in BL-0 at 37 min.
