In present study, perforated ray cells were recorded for the first time in the species of Berberis amurensis and Berberis poiretii (Berberidaceae) and Mallotus japonicus and Sapium japonicum (Euphorbiaceae) that grow in Korea. These ray cells had simply perforations in the above species which had vessel elements with simple perforations, In Korean Berberidaceae and Euphorbiaceae, thus, the perforation types of perforated ray cells appeared to be identical with the types of perforation plates in the vessel elements is the same wood.

Methanol extracts of five Berberidaceae species were examined against tissue factor inhibitory and tumour cell growth inhibitory activity. Methanol extracts of Berberis koreana Palibin showed a strong cytotoxicity activity against SK-MEL-2 (Melanoma) tumour cell lines with more than 90% in $25{\mu}g/m\ell$ and against A549 (Lung carcinoma), SK-OV-3 (Ovarian cancer), XF498 (CNS cancer) and HCTl5 (Colon cancer), other Berberidaceae species except B. koreana species have no effect on the tumour cells. Biologically active compound, therefore, was isolated through the activity guided fractionation and purification. The structure was confirmed by NMR. FT-IR and MS to 2-(3,4-dihydroxybenzyl)-ethyl alcohol. It showed cytotoxicity activity against SNU-C4 tumour cell lines with 50.7% in $50{\mu}g/m\ell$. Methanol extracts of 5 Berberidacae species have no effect on the tissue factor inhibitory activity.

n-Alkanes (n-nonacosane and n-hentriacontane), phytosterols (campesterol and ${\beta}$-sitosterol) and phytosteryl glucosides (${\beta}$-sitosterol 3-O-${\beta}$-D-glucopyranoside and campesterol 3-O-${\beta}$-D-glucopyranoside) were isolated from the underground parts of Epimedium koreanum (Berberidaceae) and characterized by spectral data.

Berberis amurensis Ruprecht(Berberidaceae) is a medicinal plant indigenous to the middle and northern part of Korean peninsula. The woody parts of this plant have been used for the ocular, peptic and intestinal disorders. The stems of this plants were extracted with MeOH and the MeOH extract was partitioned between organic phases and water layer, successively to fractionated quarternary alkaloids. The acetone-soluble part of guarternary alkaloidal fraction had antibacterial activities and it contained four protoberberine alkaloids such as palmatine(I), Berberine(II), Jatrorrhizine(III) and coptisine(IV), and one aporphine alkaloid, magnoflorine(V). Although the isolations of the compounds I, II, IIII, IV and V from different sources were reported, this is the first report that Berberis amurensis contained the compounds. When the contents of compound I(palmatine) and II(berberine) were quantified and compared with those of other plant parts, cortex contained higher palmatine and berberine than any other part of the plant.

An intensive study of the embryology of Gymnospermium microrrhynchum was conducted to provide information regarding a discussion of the phylogenetic relationships of the genus, which is yet unstudied. Our results indicated that Gymnospermium is similar to other genera of Berberidaceae in terms of its embryological features. Nevertheless, newly reported and unique features are the well-developed endothelium and the undifferentiated seed coat type. Until the study of Gymnospermium, it may have been considered to be closer to Caulophyllum and Leontice in the tribe Leonticeae. These three genera share many morphological features as well as molecular similarities, by which they are kept in the same tribe, Leonticeae. However, very little detailed embryological data regarding these genera have been published thus far. Gymnospermium was characterized according to the basic type of anther wall formation as well as its glandular tapetum, successive cytokinesis in the microspore mother cell, two-celled mature pollen grains, anatropous and crassinucellate ovules with a nucellar cap, well-developed endothelium, its Polygonum type of embryo sac formation, its nuclear type of endosperm formation, and its undifferentiated seed coat type. In comparison with Nandina, there are many differences, such as the dehiscence of the anther, the cytokinesis in the microspore mother cells, the shape of the megaspore dyad, and the seed characteristics. Although we had no available detailed embryological information regarding Caulophyllum and Leontice, which are genera that are more closely related to Gymnospermium, we could deduce from the phylogenetic relationship that Gymnospermium, Caulophyllum, and Leontice are more closely related to each other than other genera of Berberidaceae on the basis of the seed characteristics.

남천은 매자나무과(Berberidaceae)의 남천속(Nandina)에 속하며 남천속에는 남천 단 한종밖에 없지만 관상용으로 재배되면서 많은 원예용 품종이 개발되어 보급되고 있다. 분포지역은 일본, 중국, 인도 등 동남아시아의 나라들 중 난대 및 열대에 속하는 지역에 자생하고 있으며, 우리나라에는 관상용으로 도입되어 재배되고 있는 도입수종이다. (중략)

Because the embryological features of Jeffersonia dubia are poorly understood, we conducted the first embryological study comparing it to other related genera of Berberidaceae. Important embryological features of J. dubia are as follows: the anther is tetrasporangiate, anther wall formation confirms basic type, glandular tapetum cells are two nucleate, the epidermis persistent, and the endothecium develops fibrous thickenings, anther dehiscence by two valves, meiosis in a microspore mother cell is accompanied by simultaneous cytokinesis, microspore tetrads are usually tetrahedral, pollen grains two cells at the time of anthesis. The ovule is bitegmic, anatropous and crassinucellate, archesporium single celled, development of the embryo sac Polygonum type, a mature embryo sac is ellipsoidal in shape. Endosperm formation is of Nuclear type and embryogeny Onagrad type. Seeds are arillate and seed coat exotestal type. Embryological comparisons showed that Jeffersonia resemble to Epimedium and Vancouveria rather than Berberis and Mahonia in some features, like as number of tapetal cells, cytokinesis in meiosis, and thickness of exotesta. It also resembles to Gymnospermium in mode of anther wall formation, number of tapetal cells, formation of nucellar cap, and nature of antipodal cells. Nevertheless, Jeffersonia and Gymnospermium differ from several other embryological features and molecular data too. Therefore, embryological evidences support that Jeffersonia is closely related with Epimedium and Vancouveria.
