전남 가거도에서 양지꽃속의 신종인 가거양지꽃(Potentilla gageodoensis M. Kim)을 새로이 발견하여 기재하였다. 가거양지꽃은 잎은 우상복엽이며 엽신과 엽병에 털이 있고 3개의 정소엽이 측소엽보다 크며 포복경이 없어 양지꽃과 유사하다. 그러나 가거양지꽃은 잎은 두껍고 근생엽은 흔히 5장의 소엽으로 이루어졌으며 정소엽은 광난형이고 꽃잎이 크며 소엽 가장자리에 흰털이 밀생해서 흰색 테두리가 있는 것처럼 보인다. 반면에, 양지꽃은 잎은 얇고 근생엽은 흔히 7-13장의 소엽으로 이루어졌으며 정소엽은 타원형이고 꽃잎이 작으며 소엽 가장자리에 흰털이 적은 점에서 두 종이 뚜렷하게 차이가 난다.

백두산에서 양지꽃속의 신종인 백두산양지꽃(Potentilla baekdusanensis M. Kim)을 새로이 발견하여 기재하였다. 백두산양지꽃은 잎이 우상복엽이며 엽신과 엽병에 털이 있고 3개의 상부 소엽이 하부 소엽보다 크며 포복경이 없어 양지꽃과 유사하다. 그러나 백두산양지꽃은 식물체가 소형이고 짧은 누운 털이 있으며 근생엽이 7장의 소엽으로 이루어졌고 하부 소엽이 작으며 소엽가장자리에 털이 없고 꽃잎 기부에 황적색의 무늬가 있다. 반면에, 양지꽃은 식물체가 대형이고 긴 곧은 털이 밀생하며 근생엽이 9-15장의 소엽으로 이루어졌고 하부 소엽이 크며 소엽가장자리에 긴털이 밀생하고 꽃잎 기부에 황적색의 무늬가 없는 점에서 두 종이 뚜렷하게 차이가 난다.

Korean folk medicine 'Jin Hae Cho' has been used as a remedy for neuralgia and an invigorating drug after a childbirth in Korea. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'Jin Hae Cho', studied on the morphological and anatomical characteristics of the roots of Potentilla species growing wild in Korea i.e. Potentilla chinensis Ser., P. cryptotaeniae Maxim., P. dickinsii Fr. et Sav., P. discolor Bunge, P. fragarioides L. var. major Maxim., P. freyniana Bornm., P. kleiniana Wight et Arnott, P. paradoxa Nutt., P. yokusaiana Makino and 'Jin Hae Cho' from Korea on Korean market. As a result, it was made clear that 'Jin Hae Cho' from Korea was derived from the roots of Potentilla chinensis Ser. and Potentilla discolor Bunge.

The Korean folk medicine 'Jin Hae Cho Ip' has been used as a remedy for neuralgia and as an invigorating drug after a childbirth, etc in Korea. With regard to the botanical origin of 'Jin Hae Cho Ip', several species of Potentilla (Rosaceae) has been refired, but no pharmacognostical study has yet been performed in this regard. To clarify the botanical origin of the 'Jin Hae Cho Ip', the morphological and anatomical characteristics of the leaflets and petioles of Potentilla and Sibbaldia species growing in Korea, such as P. chinensis, P. cryptotaeniae, P. dickinsii, P. discolor, P. fragarioides var. major, P. freyniana, P. kleiniana, P. matsumurae, P. paradoxa, and S. procumbens, were compared. As a result, it was found that 'Jin Hae Cho Ip' was composed of the leaves of P. Chinensis and P. discolor.

To search for useful antioxidants from plant materials, we investigated the antioxidative activity in the methanol extracts of 30 Chinese medicinal plants using DPPH method. The highest activity $(RC_{50}:\;12\;{\mu}g)$ was showed in the methanol extract of Rosa rugosa, followed by Potentilla fruticosa $(14\;{\mu}g)$, P. fragarioides $(16\;{\mu}g)$. And Geum aleppicum $(18\;{\mu}g)$. From the leaves of R. rugosa, two antioxidative compounds were isolated by a bioassay guided purification and identified as isoquercitrin and ${\beta}-glucogallin$ on the basis of $^1H-,\;^{13}C-\;NMR$, and FAB-MS data. ${\beta}-Glucogallin$ is the first report in this plant. The DPPH radical scavenging activity of ${\beta}-glucogallin\;(RC_{50}:\;8.5\;{\mu}g)$ was more effective than those of ${\alpha}-tocopherol\;(12\;{\mu}g)$ and BHA $(14\;{\mu}g)$.

To discern general tendency in relatively pure even-aged pine stands, to group the stands and to perceive neighbourhood effects a total of 39 sites of pine stand was surveyed from nearby Seoul (12 sites), Chunsung, Kangwon (13 sites) and Sosan, Chungnam (14 sites), for herb and shrub species 32, 19; 37, 19 and 41, 14 in the respective areas from September 1987 to July 1988. In terms of detrended correspondence analysis (DECORANA), the stands were subjected to ordinate with 16 physical variables and the vegetational variables. The resource ratio (N:P, N:K, P:K) as physical variables also was tried out in the DECORANA as well as independent variable (N.P.K). The outcome did not show any meaningful difference. It is suggested that there seems to be no apparent interaction among the elements in the study. Three vertical vegetation componeent, that is, tree layer, shrub layer, herb layer were subjccted to DECORANA independently, pairwisely and as a whole (a total 7 combinations). Of those analysis herb layer trial alone seems to indicate relatively clearer differences among the physical variables. In the stands nearby Seoul first axis indicated soil field capacity and exchangeable cations (K, Ca and Na) and second axis did not show any tendency. For the Chunsung stands first axis also revealed soil field capcity and amount of arganic matter and second axis showed amount of exchangeable cation (K, Ca and Na), In the Seosan 1st axis indicated pH and exchangeable cations (K, Ca and Na). For the 39 sites 4 clusters in terms of herb layer might be defined: Peucedanum terebinthaceum-Cymbopogon tortilis-Polygala japonica-Festuca ovina (1); Atractylodes japonica-Patrina scabiosaefolia (2); Potentilla fragarioides-Atractylodes (3); and Cymbopogon tortilis (4). In the neighbourhood effects study in terms of the basal area distribution, Thiessen polygon area and Gini coefficient for the Pinus thunbergii stands of Seosan the Thiessen polygon area approach seems to indicate earlier (30 years old) neighbourhood effect than the others (45 years).

This study was carried out to find out the correlation between plant groups and environomental gradient in the native grassfild near Kang Nam Express Terminal from August 26 to september 15, 1977. The correlations among plant species were calculated by using the method of x2 and the various relationships among soil environmental gradients were grouped by means of correlation coefficient. As a result, both the species and the soil environmental factors could be subdivided into four groups, and the four groups of the native grassfield were turned out to be correlated with the four groups of soil environmental factors. The first plant group (Panicum dichotomiflorum, Chenopodium album, Bidens forndosa, Humulus japonicus, Alopeculus amurensis, Potentilla fragarioides, Centipeda minima, Beckmannia erucaeformis) was formed in the releve 1∼10 reagions, organic matter by Turins's method, Total N, Exchange Ca and total of Exchange K, Na, Kg, Ca were abundent. The second plant group (Digitaria sanguinalis, Paltulaca oleracea, Echinochlea macrocrovi, Cyperus amuricus) was formed in the relve 11∼18 reagions, where Exchange Ca and total of Exchange K, Ng, Mg, Ca were little but Exchange A1 and sand were aburdent. In relve 19∼20 reagions, with much of Exchange Ca, total of Exchange K, Na, Mg, Ca, pH and a little Exchange Al, was found the third plant group (Pycreus sanguinoloentus, Cyperus amuricus, Ludwigia prostrata, Echinochloa echinata, Polygonum thunbergii, Salix glandulosa seedling) The fourth plant group (Cassia nomame, Polygnoum perfoliatum, Setaria viridis, Glocien ussuriensis, Lactuca indica, setaria glauca, Artemisia capill aris, Artmisia asiatica, Calamagrostis arundinacea, Kummerowia striata, Denothera odorata, Artemisia japonica, Carey laceolata) was formed in relve 21∼25 reagions, where organic matter by loss on ignition, Exchange Mg and Maximum water holding capacity were abundent but sand was a little. Thus it can be concluded that there is a close relationship between the vegetation group clasified by meaus of x2 and the environtal factors of soil devided by means of correlations coefficient.
