Objective : Lycii Fructus Extracts(LFE) can do Anti-hypertension activity, Antidepressant, Anti-diabetic activity. This study was designed to investigate effects of LFE on skin whitening and elasticity using melanoma cells. Methods : In this experiment, effect of LFE on cell viability, inhibition of melanin synthesis and inhibitory effect on tyrosinase and elastase. Results : More than 250 ㎍/㎖ of LFE treated group showed lowered proliferation rates significantly compared to non-treated group. More than 125 ㎍/㎖ of LFE treated groups were lower levels of melanin synthesis respectively. LFE showed inhibitory effect on tyrosinase activities in vitro. And, LFE suppressed tyrosinase activities in B16F10 cells significantly. Finally, LFE suppressed elastase type Ⅰ and Ⅳ activities in dose-dependent manner in vitro. And LFE also slightly suppressed elastase activities in vivo. Conclusion : These results suggest that LFE can inhibit melanin synthesis through ihhibitory action on tyrosinase activity and inhibt elastase activity, and also suggest that these results can be used for the study on maintaining skin elasticity or whitening.

Host plants of the Henosepilachna vigintioctomaculata are known as Solanaceae plants such as potato, tomato, eggplant and Lycium chinense. Henosepilachna vigintioctomaculata (Motschulsky) cause continuous damage from early June to mid-August in leaves of L. chinense under environmental-friendly management in Cheongyang, Chungnam. The developmental period of egg and larva of H. vigintioctomaculata were investigated. H. vigintioctomaculata were reared on L. chinense at several temperatures, for example, 15, 20, 25 and 30°C in the laboratory. In addition, the control effect of 5 eco-friendly agricultural materials were examined. As results, hatching rate is the highest to 91% at 25°C. Egg periods were 10.8, 7.7, 5.1 and 3.7 days at each tested temperature, respectively. And the total developmental periods from egg to adult were 42.7, 26.3, 18.4 and 19.4 days at each tested temperature, respectively. Otherwise, their eclosion rates from pupa to adult were showed 58%, 77%, 85%, 65% at each tested temperature, respectively. As a result of the control effect, both adults and larvae of H. vigintioctomaculata were shown a high mortality to mixture with extract of Sophora flavescens, Chenopodium ambrosioides and Melia azedarach. Additional, larvae is shown high mortality to extract of Azadirachta indica and Cymbopogon nardus. Thus H. vigintioctomaculata might be controled by using plant extract of eco-friendly agricultural materials in due season.

Objective : The purpose of this study was to investigate the synergistic effect of Angelicae gigantis Radix (AG) and Lycii fructus (LF) ethanol extracts on skin-whitening effects. Method : LFAG extracts were prepared by extracting with 80% ethanol. The efficacy of LFAG was judged by measurement of cell viability, tyrosinase activity, melanin production, tyrosinase and microphthalmiaassociated transcription factor (MITF) expression in B16F10 murine melanoma cells by lipopolysaccharides (LPS) treatment .Results : Each extract (LF or AG) inhibited the tyrosinase activity in a dose-dependent manner. The co-treatment of LFAG extracts (25 μg/mL LF plus 25 μg/mL AG) markedly suppressed the LPS-induced cellular tyrosine activity, melanin production, tyrosinase and MMP-1 expression in B16F10 murine melanoma cells. These suppressive effects were synergistically increased by their combination.
