The objective of this study was to find out a nomenclature and a code number for fruit commodities from the Codex Alimentarius Commission (Codex) corresponding with a commodity name used in South Korea. In addition, nomenclature or classification for commodity that needs an alteration or detailed examination domestically was determined. In this study, 'Food Code (Korean and English version)' and 'Pesticide MRLs in Food' from the Ministry of Food and Drug Safety and 'Codex Classification of Foods and Animal Feeds' were used. As results, regarding a nomenclature or classification used in South Korea, it appeared that alteration or further examination was needed for the following (English name of commodity, coming from an English version of Food Code). First, reconsiderations for classification of Chinese matrimony vine, fig, five-flavor magnolia vine, and pomegranate are needed as they are classified differently between Korea and Codex. Second, in any case of Korean or English language, nomenclature of commodity is different even within Korea or when it is compared with Codex. Such commodities are: Asian citron, Chinese bush cherry, Chinese matrimony vine, coconut, crimson glory vine, date palm, five-flavor magnolia vine, five-leaf chocolate vine, Japanese apricot, Japanese cornelian cherry, jujube, kiwifruit (golden kiwi), Korean black berry, Korean raspberry, kumquat, lychee, mandarin, persimmon, plum, quince, raspberry, and trifoliate orange. Third, reconsiderations for peach and raspberry nomenclatures are needed as it is currently unclear whether 'peach' includes nectarine and an English nomenclature, 'raspberry', is used in Korea for both various varieties (red, black) and one specific variety.

The objective of this study was to investigate the anti-obesity and lipid-lowering effects of extracts of persimmon leaf (PWE), buckwheat leaf (BWE), and chinese matrimony vine leaf (LWE) in rats fed a high-fat diet (HFD). Male Sprague-Dawley rats (n=40) were divided into four groups: HFD (35% fat, w/w), HFD (38.5% fat, w/w) supplemented with PWE (10%, w/w), BWE (10%, w/w), and LWE (10%, w/w) groups. The epididymal, perirenal, and interscapular white adipose tissue (WAT) weights as well as plasma leptin level were lowest in the LWE group. Supplementation with PWE and BWE also tended to lower the perirenal and retroperitonal WAT weights compared to the HFD control group, and there was a significant decrease in plasma leptin concentration. Furthermore, plasma triglyceride concentration, hepatic cholesterol content, and hepatic lipid droplet accumulation were significantly lower in the PWE, BWE, and LWE groups than in the HFD group. BWE supplementation markedly lowered plasma total cholesterol concentration, although there were no significant differences in plasma HDL-cholesterol concentration and ratio of HDL-cholesterol/total cholesterol among the groups. Hepatic HMG-CoA reductase activity was significantly higher in the PWE and LWE groups than in the HFD group, and hepatic ACAT was not changed by extract supplementation. However, supplementation with PWE, BWE, and LWE significantly increased fecal acidic sterol content in rats fed a HFD. These results suggest that supplementation with PWE, BWE, and LWE may be an effective anti-obesity strategy by lowering body fat weight and improving plasma and hepatic lipid profiles in HFD-fed rats.

This experiment was conducted to find out high antioxidant activity varieties of chinese matrimony from the 131 accessions which conserved at Cheongyang Gugija Experiment Station. The status of the 131 accessions were composed 21 of local varieties, 20 of introduced species and 90 of improved races. The anti-oxidant activity using DPPH and $IC_{50}$, 45 accessions out of 90 showed high activity in free radical scavenging ability as less than $200{\mu}g/m{\ell}$ in improved races, while nine and six accessions from the introduced species and local varieties, respectively. At the stem part, the highest three anti-oxidant varieties among 131 accessions are "C0148-94", "D0148-72" and "Cheongdae", while China collection 1 in leaf part. Since "Cheongdae" is the progeny from the "Cheongyang Jaerae 5" and "Myungan" and those two varieties, "C0148-94" and "D0148-72" are from the Myungan and Cheongdae, high anti-oxidant activity can be inherited in Chinese matrimony vine.

This study was conducted to investigate the actual conditions of intake of Korean traditional beverages in 273 female university students in Seoul, Korea. The subjects of this study consisted of 128 food and nutrition majors and 145 non-majors. Questionnaires were administered to the subjects who had an average age of 20 years. Two-hundred and nineteen students (80.2%) lived with their parents. Regarding the type of beverages subjects often drink, coffee was the most preferred (51.3%) overall, and non-majors (4.1%) were shown to drink traditional beverages more often. Regarding preference for traditional beverages, most subjects (72.5%) responded that they liked their own traditional beverage. However, for frequency of intake of traditional beverages, 48.7% answered they do not drink any traditional beverages. The reasons why subjects like traditional beverages were taste (71.7%) and health (26.3%), and the type of traditional beverages they often drink were Yulmu tea (35.9%), Sik hae (30.8%), and Yuja tea (10.6%), in order. Regardless of major, ginseng tea, jujube tea, mulberry-leaf tea, Chinese matrimony vine tea, ssanghwa tea, ginger tea, and omija tea were found to be satisfactory traditional beverages. Therefore, due to the low intake frequency, preference, and satisfaction of traditional beverages, new traditional beverages that can meet the standards of female students should be immediately developed.

This study was conducted to determine the variation of phenolic compounds in the leaf and stem of 131 accessions of Lycium chinesis Miller. The levels of total phenolic compounds in the leaf of L. chinesis ranged between 8.8 to $14.9mg\;g^{-1}$ and among them 60% of the accessions belong between 11.6 and $13.5mg\;g^{-1}$ for the content of phenolic compounds in the leaf. The accession CB03286-89 contained the highest total phenolic compounds among the accessions tested, which was 1.7-fold higher than that of the lowest content accession CBP03310-250. In the stem, the total phenolic compound of 131 accessions of L. chinesis ranged from 6.8 to $12.4mg\;g^{-1}$, showing slightly lower level than that in the leaf. The content of (+)catechin was highest in the leaf and stem of accession CB03286-89 and Japan No.1, respectively. Myricetin was detected in the leaf of seven accessions (i.e. Geumsan jaerae, Japan No.1, China collection No.1, CL32-13, CB04329-13, China collection No.12 and CB03286-89) and in the stem of five accessions (i.e., Japan No.1, China collection No.1, China collection No.12, CB03286-89 and 99797). Accessions had a great influence on the content of phenolic compounds. So, accessions-specific phenolic compound profiles might be helpful for commercial use or production of phenolic compounds in L. chinesis.
