Diterpenoids from Eragrostis ferruginea
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 35~38
Two new diterpene compounds have been isolate from the roots of Eragrostis ferruginea (Thunb.) Beauv. and their structures were elucidated as isopimara-9(11), 15-0ien-l9-ol-3-one and cassa-13(14), 15-diene-3, 12-dione by various spectroscopic me-thods. We have also isolated a known diterpene diol isopimara-9(11). 15-diene-3
더덕 ( 사삼 )의 재배방법별 일반성분 및 무기성분에 관한 연구 ( Proximate and Mineral of Dried Wild and Cultivated Codonopsis lanceolata Benth , et Hook , Fil , of Different Cultivated Groups )
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 39~45
Proximate compositions of the roots of cultured and wild Codonopsis lanceolata were examined as tile basic reasearch for the study of their source of processed foods.No significant difference in the contents was found between the wild root and thecultivated at 3
in biotronroom. In view of the results to have measured mineralswhich is included in 14 sorts of Codonopsis lanceolata and surveyed their distribution.12 kinds of minerals including T1, Co, Ge, Sm, Mo, Sc, Be, Cd, As, Ga, Bi, ph are ne-vel or little included in almost source. Other twenty-one sorts of minerals (Ni, Se,Ba, Sb, Si, Ti, B, Li, Ifs, Ca, Sr, Mn, Fe, Cu, Zn, p, Al, Na, V, Cr, K) are more or less in-cluded in all source and Ca, Mg, p, K, and Fe are metals that are included in large qu-entities in comparison with others. No minerals difference in the contents was foundbetween the cultivated temperature. The content of elements of inorganic metal differsaccording to the part of C. lanceolata.
Chromosome number of Codonopsis lanceolata
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 47~49
In an attempt to analyse the variation of chromosome numbers in Cododopsis lanceolate, 28 species of Deo-Deong have been examined for determination of chromosomenumbers. Tlle somatic chromosone numbers were counted to be 2n=16 of C. lanceolata.
Studies on the Soil Microoganisms and Physiochemical Properties in Kwangju area
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 51~58
With the soil samples collected from 33 locations in Kwangju area, the physiochemical properties of soil and soil microorganisms have been studied and the results of'the analysis were as follows ;1 . Tlle temperatilre, pH, moisture and organic matter of sampling s'tes were measured in the range of 21.O~28.O
, 4.0"6.6, 2.1"24.0% and 2.8~22.0% respectively.and that showed wide range distribution in moisture and organio mattrr particulary.and averase was 24.

The Study on the Year-round Production of Colocasia antiquorum Schott in Medicinal Herb
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 59~65
These Experiments were carried out to test the possibility of produciilg taro earlyplanting culture growing them in polyethylene vinyl house and/or polyethylene tunnneland/or polyetllylene mulching without any supplenmentary heat. Out of various combin-ation of the method of using polyethylene film, Plenty more of taro in polyetllylenehouse+tunnel+mulching on the 5th of March showed the clear possibility that tarocould be harvested on middle of july, which was harvested 3 months earlier thanwhen growing in the open culture . Therefore, it is concluded that taro could be grownas an early crop by using polyetlene film.
The latest Situation of Medicinal Hers Culture and Improvement of Distribution Structure
Korean Journal of Plant Resources, volume 4, issue 2, 1991, Pages 67~74
Many people have a growing interest on the health result from economic improvement, various environimental pollution and stress, and unrest on the adult diseases etc.In these result, demand for the herb medicine continues to expand. Farmers of theour country have a hardship in the farm management owing to of opening and liberaliza-tion, and make strenuous efforts on the devclopment of substitute crops to overcomethese differties. Government nowadays recommends the cultivation of the economiccrops like a flowers, medicinal herbs mushroom and clean vegetables. Medicinal herbsare specially profitable among these crops because herbs are possible to culture inwaste land, disused field and slope land, and owing to need less labor and competitionthan those of other crops. The most important problem is the facts that the compli-cation of currency structure of herb medicine inflicts mucll loss to cultivators. Therefore, this study was investigated the state of herb cultivation and the facts to be imploved in currency structure of the harvested herb medicine.1 . The cultivating area and output have been gradually increased and much produc-ted in Kyoungbuk, Kangwon, Choongbuk, Cheonbuk and Cheonnam province in or-der of cultivating area 2. Collection amount of wild herb medicine is decreasig bythe reason of the varous difficulties on the collection. 3. Cultivators of medicinal herbscan make agricultural management more resonable in information exchange on theherb cultivation, purchase of seed, fertilizer, chemicals and other materials, and sell-ing of harvested herb medicine by organization of cultivator fraternity. 4 Cultivatorshave to exclude intermediary margin by the development of direct transaction andcontract cultivation with medicinal herb store, drug manufacturer, chinese meicinehospital and trading firm etc. And also, by the performing exportation with foreign consumer.
