Acanthopanax divaricatus var. albeofructus (ADA) is commonly ingested as a traditional medicine or as a component of a health drink in Korea. In this phytochemical study, nine phenolics (1 - 9) and three lignans (10 - 12) were isolated from the MeOH extract of the stems of ADA. Chemical structures were elucidated by comparing spectroscopic data with reported values. Nuclear factor kappa B ($NF-{\kappa}B$) inhibitory activity of the isolated compounds was evaluated using an $NF-{\kappa}B$ luciferase assay in HepG2 cells. Among them, compounds 1, 3 - 8, and 11 showed significant inhibitory effects on $TNF{\alpha}$-induced $NF-{\kappa}B$ transcriptional activity in a dosedependent manner, with $IC_{50}$ values ranging from 13.25 to $37.36{\mu}M$. Further studies on potential anti-inflammatory effects and the benefits of phenolic and lignan components from ADA are warranted.

인삼(Panax ginseng C.A. Meyer)은 두릅나무과(Araliaceae)에 속하는 식물로 동아시아에서 2,000여년 전부터 보기(補氣)제로 사용된 중요한 약재이다. 홍삼은 인삼의 뿌리를 찐 것으로, 고려시대 이전부터 쪄서 말리는 가공법이 있었던 것으로 알려져 있다. 건강기능식품에서 말하는 홍삼제품은 홍삼을 원재료로 하여 이를 분말화하거나 물이나 주정으로 추출하여 농축 또는 발효하여 식용에 적합하며, 진세노사이드Rg1과 Rb1의 합이 0.8~34 mg/g이 되어야 한다. 2011년 한국의 건강기능식품 시장은 약 3조 6,000억원에 이르며, 홍삼시장은 1조 2,000억원에 이른다. 2007년 6,420억원이었던 홍삼시장이 5년만에 두배가 된 것이다. 홍삼시장이 성장하면서 한국인삼공사(정관장)와 농협중앙회(NH한삼인), 동원F&B(천지인), 웅진식품(다채움수) 등의 회사가 기초연구와 다양한 제품개발을 통하여 경쟁하고 있다. 한국인삼공사의 경우, 최근 식품의약품안전청으로부터 홍삼의 '항산화' 기능에 대하여 건강기능식품기능성원료 인정을 받았고, '홍삼정타브렛'을 출시하였으며 '홍이장군' 브랜드를 리뉴얼하였다. 농협중앙회에서는 이미지 향상을 위한 '지성이면 한삼인' 시리즈와 짜 먹는 '뽀로로 홍삼 젤리'를 출시하였고, 동원F&B은 '홍송조화건조'를 제조공정에 도입하였고, 캡슐형태의 제품을 출시하였으며, 최근에는 꼬마버스 타요를 활용하여 '천지인 꼬마버스 타요' 시리즈를 개발하였다. 웅진식품, 대상웰라이프 등에서도 사포닌이 흡수되기 좋게 만든 '발효홍삼' 제품을 출시하고 있다. 향후 홍삼시장의 지속적인 성장을 위해 기초연구와 소비자의 니즈에 맞는 국내시장만이 아닌 해외시장까지 나아갈 수 있는 특화된 제품 개발이 절실히 요구되는 시점이다.

Eight aromatic acids in Panax ginseng were determined by GC. Ultra-1 $(25\;m{\times}0.2\;mm{\times}0.33\;{\mu}M)$ capillary column was employed with temperature programming from $150^{\circ}C$ to $240^{\circ}C$ at a rate of $3^{\circ}C/min$. The mean contents of eight aromatic acids in 8 white ginseng samples were as follows; salicylic acid: 4.30 ppm, cinnamic acid: 18.2 ppm, vanillic acid: 4.22 ppm, gentisic acid: trace, syringic acid: 6.69 ppm, p-coumaric acid: 13.3 ppm, ferulic acid : 21.9 ppm, caffeic acid: 24.3 ppm, respectively.

Continentalic acid (CA, (-)-pimara-8(14), 15-diene-19-oic acid) was isolated from the roots of Aralia cordata (Araliaceae) using bioassay-guided fractionation of a crude chloroform extract. The antibacterial activity of CA against Enterococcus faecalis and Enterococcus gallinarium was estimated by determining minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs). CA exhibited potent activity against standard vancomycin-resistant enterococci (VRE) and vancomycin-susceptible enterococci (VSE), with MICs and MBCs values between 4 and $8{\mu}g/mL$ and 4 and $16{\mu}g/mL$, respectively. This compound exhibited potent activity against strains of VRE, which are highly resistant to clinically useful antibiotics. These findings suggest that continentalic acid may be useful in controlling enterococcal infection.

The saponins of two- and four-year-old American ginseng plants (Panax quinquefolium L.) (Araliaceae) collected in July and September were studied. American ginseng saponins (panaquilins) differ from Korean ginseng $(Panax ginseng\;C.A.\;M_{EYER})$ saponins (ginsenosides). The American ginseng saponins separated and named were panaquilins A, B, C, D, E-1, E-2, E-3, G-1, G-2, (c) and (d). One-dimensional thin-layer chromatography did not completely separate panaquilin mixture and was subject to misinterpretation. The panaquilins were more accurately separated and identified by the two-dimensional thin-layer method established. Some differences in American ginseng saponins were dependent upon the plant age, time of collection, and part extracted. The American ginseng sapogenin components are panaxadiol (panaquilins B and C), oleanolic acid (panaquilin D) and panaxatriol (panaquilin G-1). The panaquilins E-1, E-2 and E-3 mixture contained both panaxadiol and panaxatriol. The genins of panaquilins A, (c), (d) and G-2 were not identified. In addition, ${\beta}-sitosterol$ and stigmasterol were identified from the root ether extracts.

Panax ginseng root has been widely used as an important drug for thousands years in China, Korea and Japan. The main effective components of ginseng have been believed to be saponins. However, ginseng cultivation is very difficult and needs many years for growth. It has already been shown that Panax ginseng callus produces a considerable amount of the same kinds of saponins as in intact plants. Various culture conditions were examined for increased production of ginseng saponins by cell culture. The saponin contents and the growth rates in two cell lines of ginseng callus were compared in static and suspension cultures, rotary and reciprocal shaking cultures. It was shown that the growth rate in rotary shaking cultures of D5-B2K-B2K callus was the highest and ginseng saponin production was most effective in reciprocal cultures of D5-B2K-B2K callus. The saponin content per fresh weight of the culture was 1.03 times higher than that of the fresh ginseng root.

High performance liquid chromatography(HPLC) was used for the determination of eleutherosides B and E in various parts of Acanthopanax species. Eleutheroside B was detected in the stem (1.45 mg/g) and the root (0.59 mg/g) of A. senticosus and the stem (0.31 mg/g) of A. senticosus grafted on A. sessiliflorus. But there is no detection of eleutheroside B in A. sessiliflorus and the root of A. senticosus grafted on A. sessiliflorus. Eleutheroside E was detected in the stem (0.92, 0.97 and 0.30 mg/g, respectively) and the root (0.65, 0.94, 0.34 mg/g, respectively) of A. senticosus, A. sessiliflorus and A. senticosus grafted on A. sessiliflorus.

The fruits of Eleutherococcus sessiliflorus (Rupr. & Maxim.) S. Y. Hu (Araliaceae), as edible fruits, were traditionally used for ingredients of wine or tea in Eastern Asia. In addition to, the fruits of E. sessiliflorus were known for having antioxidant and anti-inflammatory effects. Recently, we investigated that the ethanolic extracts of E. sessiliflorus fruits (DHP1501) have effects on hypertension via vasorelaxation and decrease of blood pressure. In the present study, we investigated that the gene and protein expression levels of endothelial nitric oxide synthase (eNOS) was increased by treatment of DHP1501 in HUVECs. Moreover, we confirmed the angiotensin converting enzyme inhibitory activity of DHP1501 through in vitro tasks. Therefore, DHP1501 could be a candidate of functional food for alleviating hypertension.

The study on phytochemical analysis and the biological activity of Kalopanacis Cortex was carried out in this research. As a phytochemical result, liriodendrin as a lignan glycoside was isolated and characterized. Two subfraction separated from the acidic substance of $CHCl_3$ fraction were saturated and unsaturated fatty acid, respectively. Saturated fatty acid mixture identified from GC-MS tool was as follows: palmitic acid, stearic acid, arachidic acid, heneicosanoic acid, docosanoic acid, tricosanoic acid, tetracosanoic acid, pentacosanoic acid, hexacosanoic acid and octacosanoic acid. Unsaturated fatty acid was found to be linoleic acid on the basis of spectroscopic method. An active principle of liriodendrin exhibited significant antihepatotoxic activity but failed to show a considerable antiedemic activity. In this paper, the result of writhing test on liriodendrin was also described.

Acanthopanx senticosus (Araliaceae) is a long-lived woody species primarily distributed throughout East Asia. This species is regarded as medically and ecologically important woody plants in Korea. To identify the variation of the RAPD patterns between domestic and foreign A. senticosus species, 22 random primers were applied to Korean A. senticosus and A. senticosus for. inermis, Chinese and Russian A. senticosus. Six primers of them could be used to discriminate the origins and 58 polymorphisms among 92 scored DNA fragments. Six bands are specific for Korean A. senticosus and A. senticosus for. inermis. Especially, three primers, OPD04, OPD11 and OPE10, were useful to differentiate between domestic and foreign Acanthopanax species. RAPD analysis was a useful method to discriminate among A. senticosus populations or accessions and Korean accessions are distinct genetically.
