Artemisia capillaris Thunb. is widely used in the herbal medicine field. This study describes the antidepressant effect of a flavonoid (chlorogenic acid) isolated from the Artemisia capillaris Thunb. The expression of the pituitary gland and hypothalamic POMC mRNA or plasma ${\beta}$-endorphin levels were increased by extract of Artemisia capillaris Thunb. or its flavoniod administered orally. In addition, antidepressant activity was studied using the tail suspension test (TST), the forced swimming test (FST) and the rotarod test in a chronically restrained immobilization stress group in mice. After restraint stress (2 h/day for 14 days), animals were kept in a cage for 14 days without any further stress, but with drugs. Mice were fed with a diet supplemented for 14 days and during the behavioral test period with chlorogenic acid (30 mg/kg/day). POMC mRNA or the plasma ${\beta}$-endorphin level was increased by the extract of Artemisia capillaris Thunb. and its flavoniod. In addition, the immobility time in TST and FST was significantly reduced by chlorogenic acid. In the rotarod test, the riding time remained similar to that of the control group at 15 rpm. Our results suggest that the flavonoid (chlorogenic acid) isolated from Artemisia capillaris Thunb. shows a potent antidepressant effect.

Genus Artemisia occurs as a hardy plant and has a wide range of culinary and medicinal features. In this study, we aimed to describe the melanin inhibitory activity of one Artemisia species, i.e., Artemisia capillaris Thunb. Ethanol extracts of fermented Artemisia capillaris (Art.EtOH.FT) and non-fermented Artemisia capillaris (Art.EtOH.CT) were tested for their ability to inhibit tyrosinase activity and melanin pigmentation. Both extracts showed dose-dependent inhibition against ${\alpha}$-melanocyte stimulating hormone-stimulated melanin formation and tyrosinase activity, without cytotoxicity. At $100{\mu}g/mL$, both extracts showed greater inhibition than kojic acid, the positive control. Protein expressions of microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), tyrosinase-related protein 1 (TRP-1), and tyrosinase-related protein 2 (TRP-2) at the transcriptional level were determined by using real-time and semi-quantitative polymerase chain reaction. To complete the mechanistic study, presences of upstream elements of MITF, the phosphorylated-extracellular signal-regulated kinase (p-ERK), and phosphorylated-mitogen-activated protein kinase kinase (p-MEK) were confirmed by using western blot analysis. Expressions of p-TYR, p-TRP-1 and p-TRP-2, downstream factors for p-ERK and p-MITF, were translationally inhibited by both extracts. Art.EtOH.FT induced more potent effects than Art.EtOH.CT, especially signal transduction effects. In summary, Artemisia capillaris extracts appear to act as potent hypopigmentation agents.

Artemisia capillaris Thunb. (Compositae) is a native herb of East Asian countries and has used for the treatment of jaundice, high liver fever, and digestive diseases for a long time, as well as being developed as the source of herbal preparations until now. The major components from A. capillaris were chlorogenic acid (1) and its derivatives substituted with caffeoyl moieties, such as 3,5-dicaffeoylquinic acid (2) and 4,5-dicaffeoylquinic acid (3), and coumarins, such as scoparone. In the study, four compounds, chlorogenic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid and scoparone (4) in the 70% ethanolic extract of A. capillaris were simultaneously determined by using HPLC-UVD system. This method was validated with the terms of linearity, precious and accuracy according to ICH guidelines. The developed method was successfully applied for the quantitative analysis of Artemisia genus, A. capillaris, A. iwayomogi, A. princeps, and A. argyi, distributed in Korea.

Randomly Amplified Polymorphic DNA (RAPD) was performed to define the genetic variation and relationships of Artemisia capillaris. Fifteen populations by the distributions and habitat were collected to conduct RAPD analysis. RAPD markers were observed mainly between 300bp and 1600bp. Total 72 scorable markers from 7 primers were applied to generate the genetic matrix, and 69 bands were polymorphic and only 3 bands were monomorphic. The genetic dissimilarity matrix by Nei's genetic distance (1972) and UPGMA phenogram were produced from the data matrix. Populations of Artemisia capillaris were clustered with high genetic affinities and cluster patterns were correlated with distributional patterns. Two big groups were clustered as southern area group and middle area group. The closest OTUs were GW2 and GG1 in middle area group, and GB1 from southern area group was clustered with OTUs in middle area group. RAPD data was useful to define the genetic variations and relationships of A. capillaris.
