This is a brief review and discussion for present status and prospects of quality evaluation in medicinal plants as oriental medicine materials (OMM). Quality in medicinal plants could be defined as the combination of origin, external appearance, effectiveness and safety, and be evaluated by plant taxonomic, morphological, physiochemical and biological methods. For high-quality improvement and standardization of OMM, medicinal plants should be produced through using proper species or good variety and standard cultivation method in suitable cultivation area. Standardizing of quality means to meet with minimum qualifying criteria of OMM in the market while improving of quality to be over standard quality of medicinal piano in production. For making new high quality and standardized products, we need to keep standard field plants, standard OMM, standard plant specimen, and standard compounds. Researchers and administration have to study and propose the quality factors and their evaluating techniques and criteria, so high-quality and standardized produce of medicinal plane could be produced and distributed under the control of the relevant regulations, and would be contributed to increasing of national health.

This study is intended to be used as the basic material for the taxonomic research by observing the stages of skeletal development of Luciogobius grandis larvae compared to the skeletal development patterns of the same fish family of Gobiidae. 3 days after hatching (DAH), the preflexion larvae was 4.01±0.11 mm (n=5) in average total length (TL) and the frontal began to ossify in the skull. 17 DAH, the advanced postflexion larvae was 5.37±0.05 mm (n=5) in average TL the supraoccipital and epiotic were ossified in the cranial bone. 36 DAH, the juvenile was 12.2±0.20 mm (n=5) in average TL and the urohyal was ossified in the hyoid arch. In addition to one hypural bone being ossified, the first, second, third and fourth were combined and were made three bone fragments and then, the bone ossification of all skeletons was completed.

Six species of false spider mites were collected and ciassifled in South Korea. Among them, a taxonomic description was carried out on the following four species new to Korea: 1. Aegyptobia nothus Pritchard and Baker, 2. Pentomerismus taxi (Hailer), 3. P. oregonensis McGregor, 4. Brevipalpus lewisi McGregor. And also esterase and alkaline phosphatase patterns obtained by polyacrylamide slab gel electrophoresis were compared on some spades. Esterase rymogram showed difference among species in band number and mobility.

A thin-layer chromatographic study was made of the chloroform-soluble and flavonoid fractions from the fruit peels of 16 species, 2 varieties and 5 formas of the Citrus plants cultivated in Je Ju Island for their interspecific relatinships. In addition, 3 hybrids and 9 native plants were also studied for their taxonomic position. Three phenograms were developed from these chromatographic data after cluster analysis via the unweighted paired group method using rithmatic average by Sneath and Sokal. These plants were grouped into 5 alliences based on the phenogram obtained from the chloroform-soluble fracitons, which were nearly identical to the subgenus rank by Tanaka, and rutinoside and neohesperidoside groups by Horowitz. Those from the flavonoid and methanol-soluble fractions were not able to evaluate the morphological classification except for a few cases.

Through total fatty acid analysis by the Gas chromatography, 17 different fatty acids were identified from the sap extracted from bark of Korean Rhus(Anacardiaceae), six species. Linoleic acid(C18 :2) and oleic acid(C18 : 1) were identified as major fatty acids for the species investigated, but except in R. chinensis.In the fatty acid composition for the species, one or two specific-fatty acid was detected, and its could be utilized as a useful taxonomic character.The result of cluster analysis by the 22 reliable characters in the fatty acid composition suggested first group was R.trichocarpa and R. succedanea, the second group, R.verniciflua, R.ambgua and R. sylvestris, but R.chinensis was a greatly independent species. The possible chemotaxonomic application of the fatty acid composition of bark in the genus Rhus was discussed.

The morphological characteristics of Chionanthus retusus Lindl. & Paxton in Korea are reviewed in this study through the comparison with its previous records and a distribution map of this species is created using previous flora and voucher specimens. The leaf epidermal micromorphology and the petiole anatomy are also briefly described.

A taxonomic study on marine sponges was conducted by SCUBA diving at Gageodo Island, Korea from August 1999 to July 2001. Among them, Haliclona (Gellius) coreana n. sp. turned out to be new to science. This new species seems to be close to H. (G.) arcoferus Vosmaer, 1885, based on the type of spicules. However, it is different in size of toxa and growth form. Toxa of the new species is half in length compared to H. (G.) arcoferus. The growth form is jar shaped in this new species, but flat in H. (G.) arcoferus.

The specimens of the recent conchostracans belonging to order Spinicaudata collected from freshwater habitats at 13 localities in South Korea during the period from May 1981 to May 1992 were examined. As a result of the present study, two species were identified: Caenestherielru gifuensis (Ishikawa, 1895), and Eurimnodio braueriona Ishikawa, 1895. The two species were described and figured in this paper. This is the first report of the recent conchostracan fauna from Korea.

In this study, we used pyrosequencing method to analysis of soil fungal communities on the Ulleungdo and Dokdo islands. 768 operational taxonomic units (OTUs) were analyzed from the Ulleungdo sample and 640 OTUs and 382 OTUs were analyzed from the Dongdo and Seodo samples, respectively. Compared to the species richness of Ulleungdo and the Dokdo sample, the Ulleungdo sample was higher than in the Dongdo and Seodo samples. Species diversity was much the same. The phylum Basidiomycota was dominant in the Ulleungdo sample, while the phylum Ascomycota was dominant in the Dongdo sample.

The current study describes seven species that are new to the lichen mycota of South Korea. A taxonomic description of Arthonia excipienda, A. radiata, Arthothelium ruanum, Enterographa leucolyta, Fissurina elaiocarpa, Rinodina oleae, and Thelotrema porinaceum was given and supported by distribution, ecology, and illustrations. Each species was compared with a species showing close resemblance.
