- Pectolinarigenin, an aglycone of pectolinarin, has more potent inhibitory activities on melanogenesis than pectolinarin. Pectolinarin and pectolinarigenin have been reported to be major compounds in Cirsium setidens. In the present study, we demonstrated inhibitory effects of pectolinarin and pectolinarigenin from C. setidens on melanogenesis. Melanin synthesis was decreased in both pectolinarin- and pectolinarigenin-treated melan- a cells and in a reconstructed human skin model. However, pectolinarigenin treatment showed more potent inhibitory activity of melanin synthesis than did pectolinarin treatment. The concentrations of pectolinarin and pectolinarigenin in C. setidens water extracts were determined by HPLC. Unfortunately, the amount of pectolinarigenin of C. setidens water extract was lower than that of pectolinarin. To increase the pectolinarigenin content in C. setidens water extract, several component conversion methods were studied. Consequently, we identified that microwave irradiation under 1% acetic acid was an optimum sugar elimination method. Ameliorative effects of Juniperus rigida fruit on atopic dermatitis in mice. The fruits of Juniperus rigida have been used in Korean traditional medicine for the treatment of inflammatory diseases in humans such as rheumatoid arthritis. Aim of the study: This study aimed to investigate the anti-atopic properties of J. rigida fruit in in vivo murine atopic dermatitis (AD) models. BALB/c mouse ears ad SKH-1 hairless mice stimulated with oxazolone (4 weeks) and DNCB (3 weeks), respectively, were treated with the 1% Juniperus rigida fruit EtOH extract (JFE). The JFE improved AD symptoms in both oxazolone- and DNCB-induced AD mice by accelerating skin barrier recovery function and suppressing the overproduction of serum immunoglobulin E (IgE) and interleukin 4 (IL-4). The JFE was found to contain isoscutellarein-7-O-β-xylopyranoside, cupressuflavone, podocarpusflavone A, and hinokiflavone as major components based on phytochemical analysis. Eight flavonoids were isolated from JFE, and of those, cupressuflavone and isoscutellarein-7-O-β-xylopyranoside strongly down-regulated IL-4 expression and β-hexosaminidase release in RBL-2H3 cells. Therapeutic attempts with J. rigida fruit and its active components might be useful in treating AD and related skin inflammatory diseases.
