  • The methanol extract of Arachis hypogaea shell showed antioxidative and antimicrobial activity. The methanol extract was successively purified by solvent fractionation, silica gel adsorption column chromatography, Sephadex LH-20 column chromatography and octadecylsilane column chromatography. The purified active substances were isolated by high performance liquid chromatography, and were identified as 3-methoxy-4-hydroxybenzoic acid and 4-hydroxybenzoic acid by LC-MS and GC-MS. The amount of 3-methoxy-4-hydroxybenzoic acid and 4-hydroxybenzoic acid were 3.8mg and 9.8 mg per kg of shell, respectively.

  • An efficient method of shoot regeneration of peanut is described. In vitro shoot organogenesis from the callus of cotyledon explants of Arachis hypogaea L. was stimulated by addition of Adenine sulphate (Ads) along with 6 - benzylaminopurine (BAP) and - napthalene acetic acid (NAA). Ads (13 ${\mu}{\textrm}{m}$) had a stimulatory effect on shoot bud differentiation when combined with BAP (13 ${\mu}{\textrm}{m}$) and NAA (2 ${\mu}{\textrm}{m}$). Shoot organogenesis was markedly higher (92%) from callus induced on Ads, BAP and NAA combined media than from those formed by the individual supplementation of Ads or BAP with NAA. The shoots elongated on the media with GA$_3$ (1 ${\mu}{\textrm}{m}$). Elongated plantlets rooted with MS media containing IBA (9 ${\mu}{\textrm}{m}$).

  • 땅콩의 육종년한을 단축하기 위한 세대촉진 방법을 정립하고자 포장후건에서 신대광땅콩 및 남대땅콩을 재배하고, 자방병이 지하로 침투한 후부터 80일까지 10일 간격으로 꼬투리와 종실을 재취하여 그 크기와 무게, 수분함량의 변화를 추적하는 동시에 종실의 발아율과 발아한 유묘의 활력을 조사한 결과, 자방병이 지하로 침투한 후 30∼40일에 꼬투리와 종실의 크기가 완성되었고, 이 때에 수확한 종실은 100% 발아력을 갖추며 발아 후 활력있는 유묘를 생산할 수 있는 것으로 나타났다.

  • Background: Owing to its high efficiency in lipid and protein production, peanut (Arachis hypogaea L.) is considered one of most important crops world-wide. The kernels of peanuts are undoubtedly the most important product this plant, whereas the skin is almost completely neglected in nutraceutical terms. However, peanut skin contains potentially health-promoting phenolics and dietary fiber, and there is considerable potential for commercial exploitation. In this study, we evaluated the α-glucosidase inhibitory activity of an extract of peanut skin (PS). Methods and Results: The α-glucosidase inhibitory effects of 80% ethanol extracts of peanut (A. hypogaea L. 'Sinpalkwang') skin were evaluated and found to have a half-maximal inhibitory concentration (IC50) value of 1.2 ㎍/㎖. Progress curves for enzyme reactions were recorded spectrophotometrically, and the inhibition kinetics revealed time-dependent inhibition with enzyme isomerization. Furthermore, using ultra-high performance liquid chromatography combined with quadrupole-orbitrap mass spectrometry, we identified 26 compounds in the peanut skin extract, namely, catechin, epicatechin, and 24 proanthocyanidins. Conclusions: The results suggest that peanut skin can be utilized as an effective source of α-glucosidase inhibition in functional foods and nutraceuticals.

  • The groundnut or cultivated peanut (Arachis hypogaea L.) in Korea consists of 36 domestic varieties which have been developed and registered as cultivars for the public during last 25 years. To screen and identify of Korean peanut varieties and genetic resources, we present a simple and reliable method. A methodology based on simple sequence repeat (SSR) markers developed and widely used for prominent gene identification and variety discrimination. For identification of those 36 Korean peanut varieties, 238 unique peanut SSR markers were selected from some previously reported results, synthesized and used for polymerase chain reaction (PCR). Data were taken through acryl amide gel electrophoresis and changed into proper formats for application of data mining analysis using Biomine (all-in-one functional genomics data mining program). Consequently, twelve SSR primers were investigated and revealed the differences between those 36 varieties. These primer pairs amplified 27 alleles with an average of 2.3 allele per primer pair. In addition, those results showed genetic relationship by classification method within 36 varieties. The approach described here could be applied to monitoring of our varieties and adapting to peanut breeding program.
