For the purpose of developing Korean Herbalogy with the plants of Urticaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1. There were totaled 11 genera and 44 species in Korea and among them medecinal plants are 9 genera, 19 species, some 43% in total but the number of species may be added because of similar plants. 2. According to the oriental name which can be used for medical purpose, the medicinal plants beloning to the Urticaceae were classified as Herba 10, Radix 8, Folium 3, Cortex 1, Flos 1, Rhizoma 1. Thus it was noticed that Herba was the main kind. 3. According to sum of 44 species in Urticaceae they were classified into Boehemeria genera 18, Urtica genera 9, Pliea genera 5, Elastosma genera 3, Parietaria genera 2, Pellionia genera 2, Achudemia 1, Debregeasia genera 1, Girardinia genera 1, Laportea genera 1, Nanocnide genera 1 etc. Thus it was noticed that Boehemeria genera was the main kind, some 41% in total. 4. According to nature and flavour of medicinal plants, they were classified into cold, cool; 6 each, wormth, heat; 4 each, balance 3. Thus it was noticed that cold and cool is the main in nature and flavour of medicinal plants. 5. According to the Properties and Principal Curative action, they were classified into, clearing up heat and toxin 9, drugs for urination an removing abscess 7, drugs for circulating blood and hemostasis 7, drugs for expelling wind 5, drugs for comporting embryo 4, 6. Comparing to whole medicinal plants 44 kinds, toxic durgs include minor toxin were 2 kinds, 5% of the whole. Thus toxic durgs were rare. From this result, It was revealed that the plants for medical purpose in Urticaceae was 43% kinds of the whole, in which Herba was mostly abundunt, toxic plants were so rare that it will be used for clinical treatments more easily. It is considered that many clinical experiments and approaches must be continued to use widely.

The presence of saponin, terpenoid, steroid, anthraquinone and flavonoid were screened with the usual test methods in forty five(sixty four parts) Korean plants belonging to Urticaceae, Celastraceae, Rhamnaceae, Sterculiceae and Rubiaceae. Plants were extracted with methanol and fractionated with hexane, chloroform, ethyl acetate and butanol. Each fraction was tested for the components. The result showed that in saponin test, 21 plants were positive and 11 plants were weak positive; in terpenoid and steroid test, 26 plants were strong positive; in anthraquinone test, 20 plants strong positive; in flavonoid test, 31 plants were positive and 9 plants were weak positive.

제주도의 서귀포시 상효동과 제주시 오등동의 계곡 주변에서 발견한 쐐기풀과의 몽울풀속에 속하는 미기록 식물, 푸른몽울풀(Elatostema laetevirens Makino)을 채집하여 기재하였다. 푸른몽울풀은 다년초이고 줄기에 개출모가 없는 점과 화서의 자루가 발달하지 않는 특징으로 국내 몽울풀속의 다른 종들과 쉽게 구분이 된다. 잎 표면에 광택이 없으며, 표면의 색이 청록색인 특징을 고려하여 '푸른몽울풀'로 명명하였다.

The alkaloids of thirty five Korean plants which belong to Rhamnaceae, Sterculiaceae, Celastracea, Urticaceae and Rubiaceae were screened. Plant was extracted and solvent fractionated to yield ether soluble alkaloidal fraction and butanol soluble fraction. Each fraction was subjected to alkaloidal test by Dragendorff's reaction. The result showed eighteen plants strong positive, fourteen weak and six negative to alkaloidal test.

Bioassay-guided fractionation of the aerial parts of Pilea mongolica(Urticaceae) afforded two cytotoxic triterpenoids, epi-oleanolic acid (I) and oxo-oleanolic acid (II). The structures of the compounds were confirmed by spectral and synthetic evidences. Compound I and compound II exhibited cytotoxicity against cultured human tumor cell lines, A549 (non small cell lung adenocarcinoma), SK-OV-3 (ovarian), SK-MEL-2 (skin melanoma), XF498 (CNS) and HCT15 (colon) with $ED_{50}$ values of $3.2-8.1{\mu}g/ml$ and $0.7-6.8 {\mu}g/ml$, respectively.

A newly recorded species, Boehmeria nakashimae Yahara, is confirmed for the first time to be distributed on forest edges on Jejudo Island, Korea. This species is known to be endemic to northern Kyushu, Japan. It is characterized by ovate to broadly ovate, elliptic-ovate, or sub-orbicular middle leaf shapes, serrulate-dentate and uniform margins, 17-29 teeth on one side, a short caudate or narrowly acute apex, dense glomerules at fruiting, and densely strigillose on the stems, both surfaces of the leaves, the perianth of staminate flowers, and achenes. Therefore, it is given the new name 'Je-ju-top-mo-si-pul' in Korean based on its serrulate-dentate leaf margin and geographical distribution. A description, photographs, illustrations, and keys of related taxa in Korea are provided.

한반도 미기록 외래식물인 작은잎물통이(쐐기풀과)와 남방향유(꿀풀과) 2분류군을 발견하였다. Pilea microphylla (L.) Liebm.는 서울시 및 제주도에서 관찰되었으며, Elsholtzia griffithii Hook. f.는 인천시에서 확인되었다. P. microphylla는 잎이 주걱형 또는 도란형이며, 길이는 2-7 mm로 작고 가장자리 전체가 밋밋한 특징에 의해 국내 자생하는 근연분류군과 구별된다. E. griffithii는 수상화서, 3 mm 길이의 좁은 피침형의 포와 약 2.5 mm의 상대적으로 짧은 화관을 갖는 특징으로 구별된다. 따라서, 본 논문에서는 한반도 미기록 외래식물 2분류군에 대한 국명, 종기재문, 사진 제공 및 검색표를 제시하였다.

The ethanolic extract of Fleurya interrupta Gaud, (Urticaceae) was tested for its possible neuropharmacological effects on experimental animals, For the primary neuropharmacological screening of this plant, the ethanolic extract of its aerial parts was subjected to preliminary evaluation for acute toxicity, antinociceptive activity and central nervous system (CNS) activities. At the doses of 125 and 250 mg/kg, the extract significantly (P < 0.01 and P < 0. 001) and dose-dependently increased the frequency of acetic acid induced writhing in mice. In the pentobarbitone induced sleeping time test, the extract at the above dose levels, significantly and dose-dependently decreased the pentobarbitone induced sleeping time (P < 0.001) and increased the time for onset of sleep (P < 0.001) in mice. In the open field and hole cross tests, test animals showed an increase in their movement in the both tests from the 2nd observation period (30 min) and persisted throughout the entire experimental period (240 min). These results of the extract may attribute a stimulating action on the CNS. On the basis of these findings, it can be assumed that the extract exerts its stimulating effect on the CNS in mice by interfering with the cortical function or increasing the effect of some CNS stimulating neurotransmitters.

Seven species and two varieties belonging to the genus Boehmeria Jacq. (Urticaceae) are known to be distributed in Korea. Among them, B. spicata, B. tricuspis, and B. tricuspis var. unicuspis were subjected to an external morphological study. Among the individuals believed to exhibit variations in the leaf shape, B. gracilis and B. silvestrii were newly recognized. Unlike related taxa, B. gracilis has middle leaves with an elliptic, broadly elliptic, ovate, or broadly depressed ovate shape, a regular and serrulate-dentate margin, and an unlobed and short caudate or cuspidate apex. Boehmeria silvestrii has middle leaves with 5-angled ovate, orbicular ovate or broadly ovate shapes, and 3- or 5-lobed and caudate apices. Therefore, we assigned the corresponding names 'Top-geo-buk-kko-ri' and 'Cham-geo-buk-kko-ri'. Meanwhile, the B. spicata complex (B. gracilis, B. silvestrii, B. spicata, and B. tricuspis var. unicuspis) is very closely related in terms of the morphological characters, whereas B. tricuspis exhibits no relationship. Furthermore, because the scientific name and type specimen of B. tricuspis var. unicuspis (Pul-geo-buk-kko-ri) are problematic, the correct name B. paraspicata Nakai and corresponding holotype are presented. Additionally, lectotypes of B. gracilis and B. silvestrii are newly designated here. A taxonomic treatment, descriptions, a key, photographs, type specimens, and leaf variation images of the B. spicata complex are provided in this study.
