This study investigated changes in quality and sensory characteristics of soy sauce (Kanjang) with added Astragalus membranaceus (AK) to develop a new soy sauce product with improved sensory characteristics. The pure salinity slowly increased, but AK 10% decreased. The pH was a constant in all samples. The soluble solid content (Brix) increased after 2 months, but AK 10% decreased. With increased addition of Astragalus membranaceus (AM), the optical density increased after 4 months. The amino nitrogen increased in soy sauce with AK 5%. The total free amino acid content gradually increased in soy sauce with AK 5% aged for 6 months. As the addition of AM increased, the crude protein level decreased, but there was no difference between AK 0% and 5%. The sensory tests of AK 5% after 6 months showed higher acceptance. According to the aging period, the acceptability of AK 5% was the best. The results showed that soy sauce with of AK 5% and aged for 6 months exhibits greatly enhanced quality and sensory characteristics. Therefore, it is expected to be used as a natural resources in seasoning area.

Stability of functional properties and chemical components of gamma-irradiated Astragali Radix (AR) were investigated to study the application of radiation technology for preservation and hygiene of medicinal herbs. Thus, ethanolic extracts and ethyl acetate fractions were prepared from gamma-irradiated and gamma-nonirradiated AR, respectively. Functional properties were estimated by comparing antioxidant activity (DPPH radical scavenging activity, lipid peroxidation inhibitory activity) and protective effect against oxidative DNA damage in human lymphocytes. Chemical components were compared by HPLC analysis, comparing with calycosin ($_{t}$ R= 15.111 min), which was isolated from ethyl acetate fraction as a standard material. Their antioxidant activities and protective effects against oxidative DNA damage showed no significant difference at the concentrations tested. HPLC analysis also showed almost same pattem. These results suggest that the functional properties and chemical components of AR are not affected largely by gamma irradiation, and radiation technology can be applied to preservation and hygiene of medicinal herbs.s.

Astradalus membranaceus root extract (ARE) contains saponins, flavonoids, and their glycosides. Two flavonoids, calycosin and formononetin, were predominant constituents with the different amount by diverse extraction conditions. ARE showed the anti-oxidative activities, inhibited tyrosinase activity, and increased type I procollagen expression in proportion to calycosin and formononetin contents. The clinical study also showed that skin wrinkles were significantly reduced in the test group treated with a cream formulation containging 0.1% ARE compared with a group treated with a cream formulation without 0.1% ARE (p < 0.05). These results suggest that ARE may have potential as an anti-aging ingredient in cosmetics.

In this study, rice wine cakes (Jubak) was produced using with Astragali memvranaceus with excellent antioxidant and antidiabetic effects and produced. This Jubak was applied to improve the cookies of modern taste and well-being products. The cookies according to the different ratio (added 0-1.0%) of Astragali memvranaceus and investigated the physicochemical characteristics, sensory evaluation, DPPH free radical scavenging activities, polyphenol and flavonoid contents. There were little changes in pH and density. The hardness of all treated cookies increased with Astragali memvranaceus Jubak(AJ) containing of different moisture contents. In color, L and a values of most cases increased in most of the treatments, but b value was reduced. In the sensory evaluation, the flavor and total scores showed the highest in 0.5% AJ cookies. But the higher proportion of AJ cookies that had unique flavors and tastes, so the total acceptance score decreased. The polyphenol and flavonoid contents increased in the higher proportion of AJ. In DPPH free radical scavenging activities, the control (no Jubak added) was 44%, and containing of 1% AJ cookies showed 82%. In conclusion, our study suggests that 0.5% in addition of AJ increased positive attributes and functional to cookies.

목적 : 본 연구는 황기약침액의 collagen 대사과정과 tyrosinage 활성에 대한 효과를 관찰하여 항노화 약침소재로의 개발 가능성을 알아보고자 계획되었다. 방법 : 황기 약침액이 사람 정상 섬유아세포 HS68에 UVB 조사 후 type I procollagen의 생산량 회복과 collagenage 활성에 미치는 효과를 ELISA법을 이용하여 측정하였다. 황기약침액의 tyrosinage 활성도에 미치는 영향을 측정하였다. 결과 : 황기 약침액은 사람 섬유아세포 HS68 실험에서 UVB 조사로 감소된 type I procollagen생성을 회복시키고, 통계적으로 유의하게 collagenage 활성을 억제하는 것을 관찰하였고 tyrosinage 활성을 통계적으로 유의하게 억제하지만, L-DOPA 산화는 억제하는 경향이 있는 것을 관찰하였다. 결론 : 본 연구 결과에 의하면, 황기약침액은 collagenage 활성을 억제하고, tyrosinage 활성을 억제하므로 주름개선과 미백효과가 있어 미용약침 소재로 개발가능성이 있을 것으로 사료된다.

We have investigated the trace amount in an oriental medicine in oder to determine the geographical origin by using inductively coupled plasma-atomic emission spectrometry(ICP-AES) and chemometric anlysis with principal component analysis(PCA) and pattern recognition. Astragali Radix from several agricultural places in Korea was selected as an example of the oriental medicine and analyzed by ICP-AES. The dried Astragali Radix sample was treated with $HNO_3$ and $H_2O_2$, then digested using microwave oven. Elements such as Mg, Al, K, Ca, Ti, Mn, Fe, Cu, Zn, and Ba with different concentrations were found an used for the identification of the origin of agriculture places. Especially, the concentration of Al, Fe, Zn and Ti were employed to investigate the relationship between. Astragali Radix and the agricultural places by PCA and pattern recognition. We have made a program that is based on chemometrics in analytical spectroscopy. The results of the chemometrics analysis indicated that a distinction among Yechon and Chechon, Chungson, Kurye and Chinese Astragali Radix could be made. We believe that principal component analysis(PCA) and pattern recognition is a valuable tool to identify the origin of Astragali Radix in terms of the agricultural place.

We investigated the effect of moisturizing and anti-oxidation of Astragalus membranaceus (Astragali Radix) root extract with respective to growing districts and extract methods for the purpose of development of cosmetic ingredients. Astragalii Radix was collected in Jecheon, Jeongseon, Taebaek, and Yeongju in Korea and China as growing districts. Formononetin was determinated by HPLC method as one of the various active agents in Astragalus membranaceus root extract. The 75% ethanol extract demonstrated to be more effective than $H_2O$-extracted one for a scavenging activities to DPPH radicals and reactive oxygens. The 75% ethanol extract showed $IC_{50}$ (50% scavenging concentration) of 2.162 mg/mL and 2.981 mg/mL in case of free radical scavenging activity test and reactive oxygen scavenging activity test, respectively Especially, free radical scavenging activity of isoflavonoids isolated from ethylacetate fraction was similar to scavenging activity of genistein. Astragalus membranaceus root extract of Jecheon district by sonicating extraction method was more effective in skin hydration compared with others.
