본 연구는 흑자색 알곡 품종으로 등록된 색소 2호 옥수수 알곡의 일반성분 및 색소 함량을 분석하여 기초자료로 제공하고자 수행되었다. 색소 2호 알곡의 일반성분 분석결과, 수분, 조회분, 조지방, 조단백질은 각각 8.84%, 1.44%, 5.46%, 10.31%이었다. 색소 2호 알곡의 유리당 성분으로 fructose, glucose, maltose 및 sucrose가 검출되었으며, 함량은 sucrose (1.00%) > glucose (0.63%) > maltose (0.52%) > fructose (0.44%) 순이었다. 색소 2호 알곡의 지방산 분석결과 총 11종의 지방산이 검출되었으며 포화 지방산과 불포화 지방산의 비율은 16.09 : 83.91로 linoleic acid가 50.86%로 가장 높게 나타났다. 색소 2호 알곡 추출물의 총 안토시아닌 함량은 0.24%였고, 알곡 추출물을 HPLC-MS/MS로 분석한 결과 색소 2호 알곡에 함유된 안토시아닌 색소는 C-3-G, Pg-3-G, Pn-3-G인 것으로 확인되었다.

Background : Ancanthopanax senticosus Fruits Extracts were studied in order to develop as functional pigment. The extracts were evaluated for physicochemical properties and biological activity. Methods and Results : Ancanthopanax senticosus fruits extracts were extracted by the rate of ethanol and distilled water in 1% citric acid. The extracts were evaluated for physicochemical properties by chromaticity, total sugar content, free sugar content, acidity, total anthocyanin contents. Total sugar and acidity were 0.10 brix and 0.44% respectively. Fructose and glucose were 1.54% and 0.36% respectively. The 60% ethanol extracts showed the highest extraction yield and total anthocyanin content. The α-glucosidase inhibitory activity of 60% and 80% ethanol extracts higher than other extracts. Conclusion : These results suggest that Ancanthopanax senticosus fruits extracts may be useful purple pigment for anti-diabetes activity.

Background : Aerial parts of Angelica gigas were studied in order to develop as functional pigment. The extracts were evaluated for physicochemical properties and biological activity. Methods and Results : Aerial parts of Angelica gigas were extracted by the rate of ethanol and distilled water. The extracts were evaluated for physicochemical properties by chromaticity, total sugar content, free sugar content, acidity, chlorophyll and carotenoids contents. Total sugar and acidity were 0.90 brix and 2.84% respectively. Chlorophyll and carotenoids contents were 0.24 and 0.04% respectively. The extracts were evaluated for biological activity by anti-inflammatory and anti-diabetes activity. Cell viabilities were measured by MTT assay. Effect of extracts on nitric oxide (NO) production from RAW264.7 cells was accessed by Griess reagent assay. Extracts to RAW 264.7 cells reduced amounts of nitrite by 76.0%. Conclusion : These results suggest that aerial parts of Angelica gigas Nakai may be useful pigment for anti-inflammatory and anti-diabetes activity.

Korean bullhead (Pseudobagrus fulvidraco) was collected from the Kum River areas of Kangkyung-eup, Nonsan city, Chungcheongnam-do, Korea, from April to June, 2012 and was fertilized in order to observe egg development and temperature-related cleavage rates and mitotic intervals (). The fertilized eggs were separative, demersal and light yellowish with in diameter, and did not contain oil globules. The first cleavage stages were 90 min, 80 min, 60 min and 50 min at , , and , respectively. At higher temperatures, eggs developed faster and underwent further identical development. For Korean bullhead, were min at , min at , min at and min at . There were strong negative correlations between the and water temperatures at all points studied (Y=-1.13X+58.15, =0.98, n=30, where Y is and X is temperature). The results obtained in this work will be helpful for chromosome manipulation by use of cleavage frequency data and data in Korean bullhead.

Volatile flavor compounds from the shoot and root of Angelica gigas Nakai were extracted by HE (Hydrodis-tillation extraction), SDE (Simultaneous steam distillation & extraction), and SFE (Supercritical fluid extraction system),and analyzed by GC-MS. The amount and the number of chemical components in essential oils from shoot and root by SFEwas the higher than those by other extraction methods. Respectively, thirty one constituents were identified from the essen-tial oil of the shoot and root by HE, twenty seven and twenty three constituents were identified from the essential oil of shootand root by SDE, thirty one and forty five constituents were identified from the essential oil of shoot and root by SFE. Theresult showed large differences in extraction methods and in plant parts of Angelica gigas Nakai. Also, the bioactive com-pounds in root part was identified as nodakenin and decursinol (11.95% and 8.42%, respectively) by SFE. These results sug-gested that SFE was the best extraction method for the increasing of extraction yield, the determination of volatilecomponents and the increasing of bioactive compounds in the shoot and root of Angelica gigas Nakai.
