The chromatographic separation of n-BuOH extract of the aerial parts of Prunus padus (Rosaceae) led to the isolation of two cerebrosides, and six phenolic compounds. Their structure were identified to be pinelloside (1), soyacebroside I (2), $quercetin-3-O-{\beta}-D-galactopyranoside$ (3), nudiposide (4), (+)-isolarisiresinol $9'-O-{\beta}-D-xylopyroanoside$ (5), khaephuoside A (6) and icariside F2(7) by physicochemical and spectroscopic methods. The compounds $1,5{\sim}7$ are first isolated from the genus Prunus.

To investigate the structure and the conservation strategy of natural forest at Dongdaesan, Turobong, Sangwangbong Area in Odaesan National Park, 27 plots(20$\times$20m) set up with random sampling method. Three groups were classified by cluster analyses. High positive correlations was proved between Tilia amurensis and Acer pseudo-sieboldianum, Malus faccata and Syringa reticulata var. mandshurica, Prunus padus and Viburnum sargentii, and High negative correlations was proved between Quercus mongolica and pronus padus, Tilia amurensis and Prunus padus, Acer pseudo-sieboldianum and Prunus padus. Species diversity(H') of investigated area was calculated 0.9586~1.1814.

To search for the new development of industrial application of woody plants, the chemical composition of the volatile constituents from woody plants (Evodia daniellii, Clerodendron trichotomum, Prunus padus, and Zanthoxylum ailanthoides) was determined by GC and GC/MS spectrometric analysis with the aid of NBS, Wiley Library and RI indice searches. The major constituents were t-ocimene from the leaves of E. daniellii, linalool from the leaves of C. trichotomum, benzaldehyde from the leaves and twigs of P. padus, ${\beta}$-thujene from the leaves of Z. ailanthoides, and 2-undecanone from the stems of Z. ailanthoides. These results suggested that the major volatile constituents of woody plants could be a useful lead compound in the development of functional materials for industrial application.

In order to investigate the basic vegetation information for the efficient management of the Sorbus commixta habitat in Korea, 31 plots in Mt. Chiri area were selected of which vegetation types were classified in phytosociological method and ecological characteristics were identified. As a result, the habitat was classified as S. commixta community group which was then subdivided to Prunus padus group and Picea jezoensis group. Prunus padus group was classified in Ainsliaea acerifolia subgroup and Magnolia sieboldii subgroup, while the Picea jezoensis group was classified in Rhododendron mucronulatum subgroup and Echinopanax horridum subgroup. Thus, the forest vegetation of S. commixta was classified in 1 community, 2 groups and 4 subgroups, and found to have 4 vegetation units in total.

To investigate the structure and the conservation strategy of Taxus cuspidata forest and at Birobong area in Sobeaksan. 24 plots(400$m^2$) set up with random sampling method. Four groups were classified by cluster analysis. High positive correlations was proved between Quercus mongolica and Symplocos chinensis, Rhododendron schlippenbachii and Pinus densiflora, Taxus cuspidata and Acer pseudo-sieboldianum, Prunus padus and Eunonymus macroptera, Acer mono and Styrax obassia, and high negative correlations was proved between Quercus mongolica and Taxus cuspidata, Prunus padus and Eunonymus macroptera, Rhododendron schlippenbachii and Taxus cuspidata, Acer pseudo-sieboldianum, Prunus padus and Eunonymus macroptera. Species diversity(H') of investigated area was calculated 1.3702-2.9119. To conserve Taxus cuspidata forest at Birobong area in Sobeaksan, research and rescription on the declining of Taxus cuspidata. forest was needed and Quercus mongolica, Styrax obassia, Tripterygium regelii and Weigela subsessilis in the Taxus cuspidata forest should be cleared out.

In this research, botanical extracts containing green tea, Saururus chinensis and Prunus padus were tested to see possibility as shampoo. Leaves of Green tea and Saururus chinensis were extracted with hot water. Prunus padus bark extract was applied reverse osmosis and ultrasonic extraction. When interfacial tension was measured among shampoo including botanical extracts, Sodium dodecylsulfate(SDS) and Quillaja Bark Saponin(QBS), that of shampoo was lower than that of SDS and QBS at lower concentration, however, it showed similar interfacial tension at 100% concentration. Shampoo showed moderate antimicrobial activity in Staphylococcus aureus and Candida albicans. Botanical extract did not indicate cell toxicity up to $350{\mu}g/ml$ concentration in MTT assay. Shampoo containing botanical extract was stable for 3 months, however, it showed considerable variation in pH and viscosity. In conclusion, shampoo containing botanical extract shows strong possibility for natural shampoo if the formulation is modified.

Leaf morphology was examined for Prunus species from Jeju Island. Analyzed were the leaf blade length, petiole length, width of blade, number of veins and angle of the base to the mid-vein as quantitative characters and the distribution of trichome, position of glandsand leaf features qualitative characters. A total of 25 OTU were phenetically analyzed by UPGMA. The resuling phenograms slightly differ from the currently recognized taxonomic system in two points. Prunus mume was clustered with P. padus and P. buergeriana. Prunu spendula and P. yedoensis were separated from the cluster of P. jaamasakura, P. speciosa, P. sargentii and P. jamasakura var. quelpaertensis. Except for the members of subgenus Cerasus, subgenera Padus (P. buergeriana and P. padus), Microcerasus (P. japonica) and Amygdalus were well defined. Some morphological characters of leaves such as the ratio of blade length to width, the length of blade to petiole, number of veins, the distance between the gland and base, the angle of base to mid-vein, and the distribution of trichome were useful as diagnostic features for Prunus from Jeju Island.

The leaves and young shoots of several broad leaf trees infected with powdery mildew fungi were collected and observed for the purpose of seeking for the host plants and identifying its pathogenic fungi in the arboretum of Forest Research Institute, Seoul from October to November 1982. Of these, Prunus serrulata var. spontanea, Prunus padus, Celastrus flagellaris, and Fraxinus ${\times}$ chiisanensis were found out to be new host plants of powdery mildew fungi in korea. Morphological characteristics of imperfect state and perfect state of powdery mildew fungi on 4 new host plants were examined. These pathogenic fungi were identified as Podosphaera tridactyla, Uncinula sengokui, and Uncinula fraxini.

In this study, natural extract including Phellodendro namurense, Eucommia ulmides Oliv and Prunus padus were tested for antimicrobial activity and safety. Antimicrobial activity was measured by using opportunistic microbes such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans. As safety test, cell viability test, single dose oral toxicity test, single dose inhalation toxicity test, repeat dose inhalation toxicity test and eye irritation test were done. From antimicrobial test, natural extract showed execellent antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, Escherichia coli. From 5 kinds of safety tests, toxicity was not observed. From experimental results, natural extract including Phellodendro namurense, Eucommia ulmides Oliv and Prunus padus showed superb safety and antimicrobial effect.
