층층나무속(Cornus) 식물 수종과 그 근연군의 계통학적 유연관계를 밝히기 위하여 종자단백질을 이중면역확산법, 사전포화처리법, 방사상면역확산법, 면역학적 전기영동법 등으로 분석함으로 혈청학적추가자료를 얻었다. Cornus florida 면역혈청을 사용한 침전반응에서 C. drummondi와 C. stolonifera는 혈청학적 유사도가 매우 높았고, C. amomum과 C. recemosa는 다음으로 높았다. Cornus와의 근연군에 해당하는 분류군 중에서 Nyssa(Nyssaceae)가 가장 가까운 근연성을 나타냈고, Corokia (Cornaceae 또는 Saxifragaceae)와 Griselinia는 매우 낮은 근연성을 보여서 Cornaceae에의 소속을 지지하고 있지 않다. 그러나 그들의 독립된 과로서 구분하기 위해서는 많은 다른 분류학적 증거가 필요할 것으로 본다. 면역학적 전기영동법과 사전포화처리법의 조합된 기술은 비교적 정교한 종자단백질 분석이 가능했다.

Twelve phenolic components were isolated from the aqueous acetone extract of the leaf of Cornus controversa H. (Cornaceae). On the basis of chemical and spectroscopic evidence, the structures of these components were established as gallic acid, $1-O-galloyl-{\beta}-{_D}-glucose$, $1,6-di-O-galloyl-{\beta}-{_D}-glucose$, $1,2,3-tri-O-galloyl-{\beta}-{_D}-glucose$, $1,2,6-tri-O-galloyl-{\beta}-{_D}-glucose$, 3,4,6-tri-O-galloyl ${_D}-glucose$, eugeniin, gemine D, quercetin, quercitrin, hyperoside and rutin.

Cornus controversa $H_{EMSL}$. (Cornaceae) is distributed widely in Korea and has been used for the treatment of diarrhea and a tonic medicine. Six compounds were isolated from the MeOH extract of the dried stem bark of Cornus controversa. Their structures were identified as gallic acid(1), scopoletin(2), arjunglucoside II(3), isoquercitrin(4), quercitrin(5) and rutin(6) by comparisons of the physicochemical and spectroscopic evidences. Among these compounds, scopoletin and arjunglucoside II were the first time isolation from this plant.

현재 한국에서 시판되고 있는 화분식품 16종을 검사하여 본 바, 15 종에서 원형 그대로의 화분임을 확인하였다. 따라서 이들 화분의 기원식물을 감별하였는 바, 국화과, 백합과, 사초과, 층층나무과, 소나무과, 자작나무과, 쥐손이풀과, 콩과, 참나무과, 벼과의 식물 화분이었다. 이들 화분은 그 표피를 그대로 지니고 있으므로 식이성 allergen으로 작용할 우려가 있다. 16종의 화분식품중 한가지 만이 화분 표피를 함유하고 있지 않았다.

Cornus officinalis (Cornaceae) is primarily grown in Asian countries. The pericarp of C. officinalis (Corni Fructus) is a well-known traditional medicine with tonic, analgesic, and diuretic properties. We analyzed methanolic extracts of Corni Fructus (grown in Korea and China) by $^1H$ NMR spectroscopy. Metabolite profiling was performed to characterize the metabolic difference between different Corni Fructus origins (Korea or China). Principal components analysis revealed significant separation between Comus Fructus from different origins. The metabolites responsible for differences were identified using loading plots, coefficients plots, and variable influence on projection followed by t-tests. As a result, 16 metabolites were identified and quantified; tyrosine, acetate, sucrose, and malate differed the most between origins. These data suggest that NMR-based metabolomics can be used to identify differences between Corni Fructus samples obtained from different regions.

The aim of the study was to determine the antioxidant activities of the plants with origin of Vietnam. The Embelia scandens (Lour.) Mez which is a species of plant in the family Myrsinaceae and Cornus hongkongensis Hemsl., which is a species of plant in the family Cornaceae were tested for antioxidant activities. Samples were prepared using 95% ethanol using DPPH assay for assessing the antioxidant activity. Ascorbic acid was used for positive control for DPPH assay. DPPH assay experiment showed that extracts of the Embelia scandens (Lour.) Mez and Cornus hongkongensis Hemsl. might have anti-oxidant activity 4.77 times and 5.65 times higher, respectively, compared to control. To determine the cell toxicity, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used. MTT assay experiment showed that Embelia scandens (Lour.) Mez might have 13.1% more toxicity whereas Cornus hongkongensis Hemsl. might have 47.3% less toxicity compared to control. Taken together, these experiments showed that Cornus hongkongensis Hemsl. extracts might have significantly higher antioxidant activities and relatively lower toxicity, compared to control.

Six triterpenoid compounds, friedelin (1), $3{\alpha}$-hydroxy-2-friedelanone (2), canophyllol (3), oleanolic aldehyde acetate (4), ursolic acid (5), and pachysandiol A (6) were isolated from the methylene chloride soluble fraction of the roots of A. japonica. The chemical structures of compounds 1-6 were determined by the basis of physico-chemical properties and spectroscopic methods such as 1D and 2D NMR. These compounds were isolated from this plant for the first time. For the isolated compounds (1-3), the inhibitory effect of IL-6 production in TNF-$\alpha$ stimulated MG-63 was examined. Among the isolates, $3{\alpha}$-hydroxy-2-friedelanone (2) showed potent inhibitory effect on IL-6 production in TNF-$3{\alpha}$ stimulated MG-63.
