This study was carried to investigate the effect of illite addition on the growth, bioactive components andvolatile compounds of leaf on Saururus chinensis Baill cultivation in greenhouse. Illite addition on Saururus chinensis Baillcultivation resulted no significant effects on the aerial part. However, the root part was highest in 5% illite addition group.Crude oil and ash amount increased as illite additives was increased. Ca of inorganics and free sugars contents were highestin 5% and 20% illite addition, respectively. Hyperoside and isoquercetin of available component on leaf were highest in 5%illite addition group, 4.02㎎/g and 4.31㎎/g, respectively. The volatile compounds in Saururus chinensis Baill leaf culturedwith illite addition amounts were isolated by solid-phase microextraction fiber (polydimethysiloxane 65㎛) and identifed bygas chromatogtaphy mass spectrometry. As the results, the 22 volatile compounds were identified from in Saururus chinen-sis Baill leaf and major volatile compounds were the α-cadinol (18.50%), myristicin (16.46%), methyl-9-methyl-tetrade-canoate (10.22%), and γ-muurolene (9.75%). Especially, the content of α-cadinol was highest in 5% illite addition group andγ-muurolene on overall illite addition group was lower than no addition group.

GAP 인증제도 도입초기의 시기적 필요성을 반영하여 GAP 인증 수삼이 어떤 소비자를 대상으로 어떠한 방향의 마케팅전략을 수행해야하는지에 대한 방향성 제시를 위해 수삼 선택속성별 부분가치를 산출하였으며 GAP 인증 수삼의 시장예상점유율 시뮬레이션, 시장세분화(segmentation), 표적시장선정(targeting), 표적시장 소비자 특성 등에 대한 일련의 연구를 수행하였다. 수삼 선택의 주요 속성인 안전성, 크기, 가격에 대한 부분가치효용을 분

This study was carried out to utilize the byproducts (flower, immature and mature berry, leaf and stem) of ginseng. Yield of byproducts were 32.7±9.8g in flower, 68.2±2.2g in immature berry, 48.5±4.3g in mature berry, 316.2±20.5g in leaf, and 296.6±15.4g in stem per 3.3m2 (180×90cm, ginseng root 675.5±35.7g/drybasis. The total saponin contents of ginseng byproducts and root are 52.36±1.24, 68.71±1.98, 168.89±0.57, 68.26±1.32, 7.85±0.61 and 35.08±0.96 mg/g, respectively. The main ginsenoside of all byproducts was Re and the highest content was 132.23±1.56 mg/g in mature berry. But flower and berry was not detected Rf and Rh1, respectively. Total polyphenolic compound content on mature berry was the highest, 2.242±0.140%, after, immature berry 〉 leaf 〉 flower 〉 root 〉 stem order. The DPPH radical scavenging activity on mature berry was the highest, 0.115±0.004 mg/mL(IC50), and the others were the same order of polyphenolic compound and ginsenoside content on byproducts.

This study was carried out to investigate the physicochemical characteristics of 3-year-old ginseng (for Samgyetang product) cultured by various seeding density in direct-sowing culture. Ginsengs were cultured by the seeding density, 275, 300, 330 352 and 396 seeds per Kan, 180×90cm area. Survived rate (82.1%) were the highest in plot of 352 seeds sowed, length and leaf width were high in plot of 300 and 352 seeds. Root yield grain was increased with increase of the seeding density in direct-sowing culture except 352 seeds sowed. Average root weight and diameter were the highest in plot of 352 seeds sowed, 31.6 g and 18.4 mm, respectively. Crude saponin and each ginsenosides content were the highest in plot of 275 seeds sowed. Rg1 content was decreased, Rc and Rb2 content were increased with increase of the seeding density. Total soluble sugar content was the highest in plot of 330 seeds sowed and the lowest in plot of 396 seeds sowed, and oligo- and disaccaride content were high in plot of 330 and 352 seeds sowed. Reological characteristics of ginsengs cultivated according to various seeding density, hardness and springness were high and maximum fracture force was low with decrease of the seeding quantity.
