Garlic (Allium sativum L.) and traditional herb has several functional properties and strong biological activities, making it useful as a functional food material. We investigated the antioxidant and anti-inflammatory activity of mixed compounds from red garlic and supplementary materials, including ginger (Zingiber officinale Roscoe), doraji (Platycodon grandiflorum), quince (Chaenomeles sinensis), citrus peel (Citri Pericarpium), and mint (Mentha arvensis). The extracts were prepared with water (W) and ethanol (E) at $70^{\circ}C$ (W-70, E-70) and $95^{\circ}C$ (W-95, E-95) for 3 h. The total content of phenolic compounds was the highest in E-70 (608.60 mg/100 g). Alliin, one of the active ingredients in red garlic, was contained at 1.18-1.29 mg/g and 0.81-0.85 mg/g in water and ethanol extract, respectively. Another active ingredient of red garlic, S-allyl-cysteine (SAC) had higher content in the water extract than in the ethanol extracts. DPPH radical scavenging activity was higher in E-70 (15.96-73.65%) at $313-5,000{\mu}g/mL$. ABTS radical scavenging activity was also higher in E-70 (5.71-77.19%) than in the others. The ROS production rate showed the same tendency as the NO production, with more efficacy in E-95. The expression level of iNOS and $IL-1{\beta}$ was decreased in the E-95 significantly at the concentration of $1,000{\mu}g/mL$ compared to the lipopolysaccharide (LPS) treated group. Based on the above results, the antioxidative and anti-inflammatory activities of the extracts of red garlic and supplementary materials were expressed by different useful substances. The contents of these useful substances were different according to the extraction solvent and temperature.

The purpose of this study was to obtain the codex classification information on the primary food commodity (fresh state) of processed foods of plant origin that are included in the Codex Classification of Foods and Animal Feeds. Furthermore, whether or not the primary food commodity is included in the primary food classification from the Food Code of Korea was investigated. The results are summarized as follows: First, the Codex Classification information (number of classification codes/number of the primary food commodity group that fresh commodities of processed foods are classified/number of primary food commodity that is not included in the Codex Classification) by a processed food group appeared to be 46/8/0 for dried fruits, 76/11/1 for dried vegetables, 54/4/12 for dried herbs, 36/1/0 for cereal grain milling fractions, 17/4/3 for oils and fats (crude), 34/8/9 for oils and fats (refined), 20/8/0 for fruit juices, 3/2/0 for vegetable juices, and 19 codes for teas (in the Codex Classification, the primary food commodity group for tea does not exist). Second, the number of the primary food commodities not included in the Food Code of Korea was 9 for dried fruits, 14 for dried vegetables, 35 for dried herbs, 0 for cereal grain milling fractions, 6 for teas, 3 for oils and fats (crude), 9 for oils and fats (refined), 2 for fruit juices, and 0 for vegetable juices. Third, it was demonstrated that caution should be exercised when using Codex Classification due to differences in food classification between Codex and Korea, such as coconut (Codex, as tree nut as well as assorted tropical and sub-tropical fruit) and olive (Codex, as assorted tropical and sub-tropical fruit as well as olives for oil production), as well as special cases in the Codex Classification, such as dried chili pepper (Codex, as spice), tomato juice (Codex, as vegetable for primary food commodity and as fruit juice for juice) and ginger (Codex, as spice for rhizome and not including as primary commodity for leaves).

This study was carried out to examine vascular plants and invasive alien plants in Gyodong Island, located at the northwestern Civilian Control Line (CCL) of Ganghwa-gun, Incheon, and to use them as basic data for systematic management of identified plants and establishing biodiversity conservation measures. The survey was conducted 13 times from April 2019 to August 2021. The vascularflora in Gyodong Island was identified as 109 families, 378 genera, 641 species, 15 subspecies, 49 variants, 8 forma, a total of 713 taxa. This was found to be about 15.36% of the total 4,641 taxa of vascular plants in Korea. The northern linage plants on the Korean Peninsula appearing in the Gyodong Island area were identified in 83 classification groups, including Red-based leaf edge (Carex erythrobasis H.Lev. & Vaniot). Korea endemic plants were identified as 16 taxa such as Seoul wild-ginger [Asarum heterotropoides var. seoulense (Nakai) Kitag.], and a total of 20 taxa of rare plants designated by IUCN were observed, including the endangered grade Beardless iris (Iris ruthenica Ker Gawl.). Floristic target species were classified with a total of 99 taxa. For V grade, Beardless iris 1 taxon was found. and also IV grade and III grade were identified in 8 taxa and 20 taxa respectively. The invasive alien plants identified as 75 taxa, such as Verbesina alternifolia (L.) Britton ex Kearney. The naturalization rate was 10.51%, and the urbanization index was calculated as 23.29%. Since large-scale construction has been currently underway on Hwagae Mt. in Gyodong Island as the target of survey area, the influx of invasive plants will be expected to promote. Therefore, it is urgent to establish in-situ protection and conservation measures for notable plants such as Beardless iris and Water smartweed [Persicaria amphibia (L.) S.F.Gray].
