“…In Damyang, the plant was referred to as Gaessuk, which was because even though it is true mugwort (Chamssuk) used as mugwort, it has relatively low availability. Considering Gnaphalium affine was more scarce and high-quality than wormwood (Heo, 2015), indicating that it originated from Goissuk (Kim et al, 2014), which is another name for the plant.…”

“…Gnaphalium affine belongs to the genus Gnaphalium of Compositae, widely distributed in East Asia such as Korea, Japan and China (Kim et al, 2014). In term of botany, Gnaphalium affine is an annual plant and germinated in the fall and entered into hibernation with its rosette leaves.…”

“…Moreover, history and use method of Gnaphalium affine is slowly being disappeared because of old people death using the plant. However, research on Gnaphalium affine in Korea only deals with the nutritive components and amino acids (Heo, 2015), the antioxidant effect (Kim et al, 2015), analysis of antioxidant activity components (Kim et al, 2014) and anti-inflammatory effect (Kim, 2015).…”

In order to establish basic data for the succession and development of use culture of Gnaphalium affine, a traditional rice cake plant resource, this study was carried out with a survey on 259 women aged 60 or over living 18 city and county in Jeonnam province. The results are summarized as follows. All respondents in the survey did not know the standard name of Gnaphalium affine. 178 repondents (68.7%) knew the plant name called in the local area. The frequency was higher in the order of Jebissuk (37.5%) > Gaessuk (21.2%) > Seorissuk (19.7%) > Gyessuk (4.3%) > Goissuk (1.9%), including duplicate responses. Of the 178 respondents who responded that they could distinguish it, 82.6% knew only one species, and 17.4% knew two in Gnaphalium affine. 62.3% of respondents said they ate dishes made from Gnaphalium affine, and 62.3% had experience cooking Gnaphalium affine. 61.8% of respondents said they ate rice cake made from Gnaphalium affine, and 40.2% had experience making rice cake with Gnaphalium affine. Edible taste of Gnaphalium affine was evaluated as 'delicious and sticy taste (4.75)'and 'above sticky (4.89)'according to criterion level 5.0. The final eating period was followed

“…콜라겐은 피부 진피층에서 matrix를 이루는 주성분으로 피부의 강도와 장력을 부여하여 외부의 자극으로부터 피부를 보호하는 역할을 한다 (Pak et al, 2016). 따라서 콜라겐의 분해는 피부의 노화와 밀접한 관련이 있어 탄력 저하, 색소 침착, 주름생성 등의 피부질 환의 원인이 된다 (Droge, 2002;Harman, 2014;Kim et al, 2014). 이러한 활성산소에 의한 질병을 억제하기위해 기능 성 식품, 의약품 및 화장품 산업에서는 BHT (butylated hydroxytoluene), BHA (butylated hydroxtanisol)등의 합성항 산화제를 사용되고 있지만 많은 연구에서 이들의 장기 식용에 따른 부작용으로 암 및 세포내 독성을 보고하고 있다 (Safer and Al-Nughamish, 1999 (Choi et al, 2017).…”

Antioxidant and Anti-aging Effects of Extracts from Rhododendron mucronulatum Turcz. in Human Dermal Fibroblast

Skin aging is associated with increased reactive oxygen species (ROS) production by human cells, which is characterized by wrinkles and atypical pigmentation. Use of antioxidants is an effective approach to prevent symptoms associated with ROS-induced skin aging. Although synthetic antioxidants have been used to remove free radicals, several studies have reported that the synthetic antioxidants have side effects that cause long-term edema, which subsequently results in cancer and intracellular toxicity. Therefore, the study of safe and functional antioxidants derived from natural products is necessary for replacement of synthetic antioxidants. In this study, the antioxidant and anti-aging effect of Rhododendron mucronulatum Turcz. extracts (RTE) on human dermal fibroblasts (HDFs) were investigated. We confirmed that RTE markedly reduced hydrogen peroxide-induced cell damage, intracellular ROS, and oxidative stress-induced senescence in HDFs. These results suggest that RTE is potential natural source of antioxidant and anti-aging compounds.

In this study, three dicaffeoylquinic acids (DCQAs) isolated from Gnaphalium affine D. DON. extracts were structurally identified and evaluated for their antioxidant activities, cellular protective effects, and tyrosinase inhibitory activities. The ethyl acetate fraction of G. affine was chromatographed, which yielded 3 DCQA derivatives of 1-3 : 3,5-dicaffoylquinic acid (3,5-DCQA, 1), 4,5-dicaffeoylquinic acid (4,5-DCQA, 2), 1,5-dicaffoylquinic acid (1,5-DCQA, 3). The structure of each compounds was determined using 1 H NMR and MS analyses. Compounds of 1-3 showed strong free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activities (FSC50 = 3.70, 5.80, and 5.50 µM, respectively) compared to those of a commonly used lipophilic antioxidant, (+)-α-tocopherol (21.90 µM). Cellular protective effects of 1-3 compounds on the 1 O2 sensitized photohemolysis of human erythrocytes were similar to (+)-α-tocopherol. 1-3 compounds also exhibited higher tyrosinase inhibitory effects (IC50 = 0.15, 0.16, and 0.13 mM) compared to arbutin (0.33 mM), known as a skin-whitening agent. These results indicate that three DCQA derivatives may be applied as an antioxidant and a skin whitening agent in food or cosmetic industries.
