  • Seeds of Acanthopanx plants need about 2 years to germinate after sowing even if full matured fruits were harvested. I leave a room for doubt that this phenomenon could be brought by the immatured embryo in seed. If it is true, stratification method for the seed propagation of Acanthopanax plants would be used more effectively to promote the growth of embryo in relatively short time. Before stratification, seeds were devided into two parts. One of them was treated for 24hrs in the concentration of $GA_3$ 100 ppm. After stratification of non-treated and treated seeds, seeds for microtechnique were taken on interval of one month for three months, and fixed in Farmer's solution. The seed sizes of Acanthopanax plants were in biggest order A. sessiliflorus, A. seoulense, A. chiisanensis, A. koreanum and A. sieboldianum. The dehiscence phenomenon of seed coat didn't show in most of the seeds that stratified, but A. koreanum only dehisced in seeds treated in $GA_3$ 100ppm. The embryos of the stratified seeds that treated in $GA_3$ showed nomal growth, complete cotyledons and procambium in hypocotyl in any species, but the non-treated seeds could not expect the germination after sowing due to poor growing of the embryo in all species. In view of the results so far achieved, it has taken long times from sowing to germinate because the seed of Acanthopanax plants has immatured embryo.

  • 1. The Korean Acanthopanax genus includes 12 kinds consisting of 9 species and 3 forma. 2. The Korean Oga-pi which is on market sale has been used as bark for the medicinal purpose, and Oga-pi shall use Radicis Cortex. That is why it is basic rule that herbalogy shall use Radicis Cortex. 3. The origin of Oga-pi on sale is Acanthopanax sessiliflorum forma chungbunensis C.S. Yook. 4. $C_{HUNG}\;and\;N_AKAI'S}$ report on A. koreanum told us that there are brown hair on the mid-leaf junction, but in addition to it, our investigation was resulted in the fact that there are thorn along mid-rib sometimes. 5. 2 kinds of new forma are similar to A. sessiliflorum, but are different in the view-point of chemotaxonomy, compared with A. sessiliflorum. In its morphology, we can find some difference between 2 kinds of new forma and A. sessiliflorum. Our effort of examination on documents tell us that the all plants growing in the central part of our country is A. sessiliflorum forma chungbunensis C.S. Yook. The one which has thorn on both side among the plants collected in Mt. Dukyu, is called A. sessiliflorum forma nambunensis C.S. Yook. 6. A. sessiliflorum is growing in the southern part in Korea, and most Chungbu Oga-pi A. sessiliflorum forma chungbunensis in the central part of our country. For the convenience of our study, the key of Korean Acanthopanax plant is classified into, I-IV, as shown on the following items: I. No hair on both side of leaf A. Flower stalk is longer than petiole, and there are thorn under the petiole (5-7 stigma).${\cdots}A.\;sieboldianum$. B. Flower stalk is longer than petiole, or same length. The serration lie down, and the stem has short thorn (stigma is divided into 3 part).${\cdots\;\cdots}A.\;seoulense$ II. There are a lot of thorn or hair on back of leaf. A. A lot of thorn and hair on the vein of leaf back, and a number of small thorn on petiole.${\cdots}A.\;chiisanensis$. B.

  • Acanthoic acid (AA) is a pimaradiene diterpene isolated from the Korean medicinal plant, Acanthopanax koreanum (Araliaceae), which has been traditionally used as a tonic and sedative as well as in the treatment of rheumatism and diabetes in korea. Proteinase-activated receptor-2 (PAR-2) agonist trypsin plays a role in inflammation, and human leukemic mast cells (HMC-l) express PAR-2. In the present study, the effect of acanthoic acid on production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and tryptase in trypsin-stimulated HMC-1 was examined. (omitted)

  • This study was executed by China along with the Tumen river, which formed border of North Korea and China. As a result 91 family, 282 genera, 363 species, 57 variety 4 species, total 424 taxa of vascular plants were identified. The examination area was include the region that had various vegetation such as upper swampy land, seashore dune, a river, a high mountain grassy plain, deciduous tree zone, evergreen coniferous forest zone. The followings are representative plants, which found in an examination area but not in South Korea. Picea koraiensis, Larix gmelini var. principis-ruprechtii, Betula playphylla, Ulmus pumila, Populus koreana, Ledum palustre var. diversipilosum, Rhododendron parvifolium, Salix brachypoda, Phacelurus latifolius, Carex gotoi, Carex capricornis, Calla palustris, Aquilegia flabellata var. pumila, Lilium davuricum, Astragalus membranaceus, Trifolium lupinaster, Ledebourieila seselodeds, Polemonium racemosum, Scutellaria baicalensis, Linnaea borealis, Thladiantha dubia, Inula helenium, Trollius hondoensis, Hypocaeris ciliata, Aconitum kirinense, Aconitum arcuatum, Potentilla viscosa var. macrophylla. And there are 21 rare and endangered species, which Korean Forest Sevice designated, such as Aconitum koreanum, Acorus calamus var. angustatus, Polygonatum stenophyllum, Drosera rotundifolia, Iris setosa, Jeffersonia dubia, Lilium davuricum, Lilium cernum, Paeonia obovata, Penthorum chinense, Phacelurus latifolius, Rosa marretii, Sparganium stoloniferum, Thymus quinquecostatus, Trillium tschonoskii, Utricularia japonica, Tripterospermum japonicum, Vaccinium uliginosum, Vaccinium vitis-idaea, etc. Especially, plants like, Acanthopanax senticosus, Jeffersonia dubia and Lillum cernum which have high values of ornamental, and medical use are in an extinction crisis. High swampy land was formed to upper stream of Tumen river. It showed representative vegitation, like Carex sp., Scirpus radirans, Eriophorum latifolium. Wetlands plant and a dune plant were mixed in down stream area of Tumen river. On a dune, seashore plants, such as Carex kobomugi, Salsola collina, Raphanus sativus var. raphanistroides, Rosa rugosa, Scutellaria strigillosa, Linaria japonica, Phacelurus latifolius were appeared frequently.

  • Anatomical study of the secondary xylem in Araliaceous plants, induding 7 genera and 11 species grown in Korea, was carried out to elucidate the relationship among genera in the family. Wood of Hedera has difbse porous and shows ulmiform pattern of angular vessels, simple perforation plate, and alternate pitting. In addition, its ray is homogeneous type II with only procumbent ray cell. Ring porous wood of Dendropanax shows ulmiform of angular vessels, simple perforation plate, alternate pitting, and heterogeneous type II ray, which has sometimes horizontal secretory cavity. Fatsia has diffuse porous wood, which shows ulmiform of angular vessels, scalariform perforation plate (3-9 bars), scalariform pitting, spiral thickening in the lateral wall of vessel, and heterogeneous type II ray with sheath cells. Kalopanax has ring porous wood, which shows ulmiform of circular vessels, simple perforation plate and alternate pitting, and heterogeneous type II ray. While K pictum appears tylose with septum, K pictum var. maximowczii appears tylose without septum. Echinopanax shows ring porous wood, ulmiform of angular vessels, simple perforation plate, scalariform pitting, and tylose with septum. And the ray of Echinopanax is paedomorphic type I composed of only upright cells. Acanthopanax genus is composed of diffuse porous wood, ulmiform of angular vessels, simple perforation plate and alternate pitting. In this genus, A. sessiliflorus has heterogeneous type II ray, apotracheal axial parenchyma and tylose with septum. A. senticosus appears paedomorphic type I with only upright cells, and tylose with septum. A. koreanum and A. sieboldianum have heterogeneous type II ray but have not tylose. Aralia is composed of ring porous wood, ulmiform of circular vessels, simple perforation plate, alternate pitting, heterogeneous type II ray, and tylose contained both septum and reticulate. On the basis of arrangement, shape, length and diameter of vessel element, the angle of end wall to vessel axis, and ray type, the line of specialization in these genera is as follow: from Fatsia, the most primitive, to the most highly specialized Aralia, throughout Hedera, Acanthopanax, Echinopanax, Dendropanax, and Kalopanax by turns. turns.
