Objectives : Alpiniae oxyphyllae Fructus (AOF) is an herbal medicine, which has been used for the treatment of fatigue, chills, and poor physical conditions. The objective of this study was to investigate the anti-inflammatory and anti-oxidative effects of AOF hot aqueous extract. Methods : The cytotoxicity of AOF extract was evaluated using the MTT assay. Nitric oxide (NO) production was measured by the Griess reaction. Prostaglandin $E_2$ ($PGE_2$) production was measured by a commercial competitive enzyme immunoassay. Cytokine production (IL-1tion co6, and TNF- F- was measured by ELISA. The anti-oxidative effect of AOF extracts was measured by the DPPH method. Polyphenol and flavonoid contents were measured by Folin-Ciocalteu's phenol reagent and aluminum chloride, respectively. Results : AOF hot aqueous extract did not show toxicity at doses of 25, 50, 100, and $200{\mu}g/mL$. AOF extract significantly inhibited NO production at doses of 100 and $200{\mu}g/mL.PGE_2$ production was inhibited by AOF extract treatment at doses of 100 and $200{\mu}g/mL$. AOF extracts reduced IL-6 production in a dose-dependent manner. IL-1ent maTNF- F- 1ent mannerd IL-6 production in uction at doses of 100 and ${\mu}g/mL$. The DPPH free radical scavenging capability was above 50% at $200{\mu}g/mL$. Conclusion : This study suggests that AOF hot aqueous extract may exert anti-inflammatory and anti-oxidative effects in a dose-dependent manner. Further studies are required for validating the safety and efficacy of AOF.

삼나물 추출물의 항산화 및 생리활성 효과를 검증하여 화장품의 기능성 소재로서의 가능성을 검증하였다. 항산화 실험 결과 삼나물의 ethyl acetate (EtOAc) 분획물 $1,000{\mu}g/mL$ 농도에서 DPPH, ABTS와 같은 전자 공여능 실험에서 가장 높은 활성을 나타났다. 미백효과 측정을 위한 tyrosinase 활성 억제도 삼나물 EtOAc 분획물에서 59.2%의 효과를 나타내었고, elastase 활성은 56% 그리고 collagenase 활성은 90% 저해효과로 항주름 효과가 검증되었다. 따라서 삼나물 추출물 특히 EtOAc 분획물은 우수한 항산화, 항주름 및 미백 생리활성으로 화장품의 새로운 기능성 소재로서 응용이 가능함을 확인하였다.

Euchrestaflavanone A (EFA) is a flavonoid found in the root bark of Cudrania tricuspidata. C. tricuspidata extract, widely used throughout Asia in traditional medicine, has been investigated phytochemically and biologically and is known to have anti-obesity, anti-inflammatory, and anti-tumor effects. It has been reported that C. tricuspidata extract also possesses anti-platelet effects; however, the mechanism of its anti-platelet and anti-thrombotic activities is yet to be elucidated. In this study, we investigated the effects of EFA on the modulation of platelet function using collagen-induced human platelets. Our results showed that EFA markedly inhibited platelet aggregation. Furthermore, it downregulated glycoprotein IIb/IIIa (αIIb/β3)-mediated signaling events, including platelet adhesion, granule secretion, thromboxane A2 production, and clot retraction, but upregulated the cyclic adenosine monophosphate-dependent pathway. Taken together, EFA possesses strong anti-platelet and anti-thrombotic properties and is a potential therapeutic drug candidate to prevent platelet-related thrombosis and cardiovascular disease.

In the present study, we investigated the anti-inflammatory effects by Alopecurus aequalis Sobol on the lipopolysaccharide (LPS)-induced nitric oxide (NO) production by RAW 264.7 cell line. Consistent with these observations, DS reduced the LPS-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein levels in a concentration-dependent manner. In addition, the release of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) were also reduced by DS. Moreover, LPS increased expression phosphorylation of $I{\kappa}B{\alpha}$, but DS showed inhibitory effect by reducing LPS-inducible p-$I{\kappa}B{\alpha}$ expression level. These results suggest that the down regulation of iNOS, COX-2, TNF-${\alpha}$, and IL-6 expression by DS are achieved by the downregulation of NF-${\kappa}B$ activity, a transcription factor necessary for pro-inflammatory mediators, and that is also responsible for its anti-inflammatory effects.

Dendrobium loddigesii (DL) is a valuable and versatile herbal medicine with the anecdotal claims of anti-oxidant and anti-inflammation. In the present study, we investigated the whitening effects of DL under various conditions with B16F10 melanoma cells. The DL extract inhibited melanin contents and tyrosinase activity in a dose-dependent manner, compared with untreated group. Treatment of the DL extract effectively suppressed the ${\alpha}$-MSH-stimulated melanin formation, tyrosinase activity and dendrite outgrowth. Moreover, the ${\alpha}$-MSH-induced mRNA expressions of tyrosinase-related protein-1 (TRP-1), tyrosinase-related protein-2 (TRP-2), microphthalmia-associated transcription factor (MITF) and protein expression of tyrosinase were significantly attenuated by DL treatment. These results indicate that DL may be a great cosmeceutical ingredient for its whitening effects.

Glehnia littoralis (Umbelliferae), a perennial herb distributed along the coastline of northern Pacific countries, is the medicinal plant used traditionally for treatment of various diseases. This review focuses on the various pharmacological activities of Glehnia littoralis for understanding about its traditional medicinal applications, medicinal uses in the modern society, and potentials for drug development Glehnia littoralis was reported to have anti-oxidant, anti-tumor, anti-amnesic, blood circulation-promoting, immunomodulatory, anti-microbial, and allelopathic activities. However, their mechanisms remain to be clarified. Because Glehnia littoralis has been prescribed in traditional Oriental medicine as a tonic herb, Glehnia littoralis can be better than other chemical drugs and medicines which exert the equal pharmacological activities. Although the activities of Glehnia littoralis are not specifically high-potent with unique mode of action, it may turn out that it can be beneficial to exert multiple pharmacological activities. In view of low toxicity, relative cheapness, presence in the diet, and occurrence in various herbal remedies of Glehnia littoralis, it needs to be prudent to evaluate its properties and applications further.

Ginseng root has been used as a tonic remedy in Traditional Chinese Medicine for centuries. Modern studies have demonstrated that ginseng root has complex components and multiple pharmacological properties. The effects of ginseng leaf, however, are not well known. Recent studies show that compared to ginseng root, ginseng leaf and stem exhibit a higher content of active compositions such as ginsenosides, polysaccharides, triterpene flavonoids, volatile oil, polyacetylenic alcohols, peptides, amino acids and fatty acids. Ginseng leaf possesses multiple pharmacological effects in the central nervous, cardiovascular, growth and metabolism systems. Additionally, the leaf has anti-fatigue, anti-hyperglycemic, anti-oxidant, and anti-aged effects. In general, ginseng leaf is quite safe, but adverse effects may occur if it is abused or is of poor quality. Thus, attention must be paid to dosages, quality, and standardization of ginseng leaf products.
