The aim of the present study was to investigate effects of the ethyl acetate fraction of an ethanol extract of Coix lachryma-jobi (ECLJ) on glucose uptake and adipocyte differentiation in 3T3-L1 cells. ECLJ phosphorylated AMP-activated protein kinase (AMPK) and its downstream substrate acetyl-coenzymeA carboxylase in 3T3-L1 cells in a time- and dose-dependent manner. Moreover, we discovered that compound C inhibits ECLJ-stimulated ACC phosphorylation. In addition, ECLJ exhibited a dose-dependent stimulation of glucose uptake in 3T3-L1 cells, and this increase was obviously attenuated by compound C. ECLJ also caused a decrease in the expression levels of adipogenesis factors such as fatty acid synthase, sterol-regulatory-element-binding protein-1c, peroxisome proliferator-activated receptor γ, and CAATT/enhancer binding protein α in a dose-dependent manner. Differentiation was examined by Oil red O staining activity after ECLJ treatment for 6 days. ECLJ decreased mean droplet size. These results suggest a possible role for AMPK in the process of adipose differentiation and that ECLJ targeted for adipocyte functions could be effective in improving the symptoms of metabolic syndrome.

Objective: The aim of this study was to incorporate Peraria candollei var. mirifica extract into the cream, to evaluate the physical properties and to conduct the skin tests in participants.Methods: Pueraria candollei var. mirifica was extracted with 95% ethanol to obtain crude pueraria extract (PCM). Crude PCM was developed as an anti-wrinkle PCM cream (B) intended for menopausal women. PCM cream was evaluated for stability of pH and viscosity, primary skin irritation, wrinkle reduction and moisturizing as well as customer satisfaction. Cream base (A) and cream purchased from the market (C) were used for comparison. ANOVA post hoc Turkey was used to analyze the variance (p0.05) of the mean comparisons between groups by cluster analysis. Results: The PCM cream appeared as white color, pH was 6.80, and viscosity was 4.069±0.01 Pa. s, as well as physical characteristic and texture, were acceptable and no irritating reaction. PCM cream exhibited a similar level of moisturizer as cream A and C. The PCM cream revealed an ability to decrease the wrinkle surface and wrinkle volume after applied for 7 and 14 d that shows the activity of this product performed from the PCM extract. Satisfaction of PCM cream showed good acceptance.Conclusion: These results suggest that PCM cream has the ability to reduce skin wrinkles. It is a good product for postmenopausal women and may also be of benefit for the general population for protection skin wrinkle.
