Petiole explant of Glehnia littoralis Fr. Schmidt was in vitro cultured MS plant medium(DUCHEFA co.) supplemented with various plant growth regulators and examined to find out their optimum combination and concentration for plantlet regeneration. We investigated optimal condition for efficient plant regeneration through adventitious shoot formation on MS plant medium with various kinds of plant growth regulators. Embryogenic calli and adventitious shoot formation were greatly influenced by plant growth regulators. Embryogenic calli induction showed a good response on MS medium supplemented with NAA and BA than others. Especially, combination of 1.0 mg/L NAA and 0.5 mg/L BA on MS medium led to the greatest frequency in adventitious shoot. The results suggest that plant regulator selection be important factor to achieve an efficient regeneration.

Glehnia littoralis Fr. Schmidt et Miquel is an important medicinal plants in East Asian countries. This plant species naturally distributed in Korea, Japan, China, and Taiwan, but it is a rare plants living in the coastal dune in Korea. To investigate the genetic variation, genetic diversity and genetic evolutionary relationships of 14 different geographical G. littoralis, ITS sequence and random amplified polymorphic DNA (RAPD) were analyzed. On the basis of ITS sequences, it was clearly showed that the ITS1 and ITS2 sequences among 14 populations are identical regardless of geographical origin excepting 2 bp in pair-wise comparison of ITS1. Furthermore, RAPD results also showed that 14 different geographical G. littoralis produce various polymorphic patterns without critical relationship among neighboring regions. These combined results suggest that the geographical variation and genetic evolution of G. littoralis is stable and provide important information on genetic diversity, and conservation of this rare plant species in situ and ex situ.

This study was conducted to evaluate the vegetation, distribution and growth pattern of Glehnia littoralis community by the DCA ordination method in eastern coast of Korea. The number of plant species growth with G. littoralis in natural habitat was found 51 taxa, and species of high frequency among 51 taxa was Ixeris repens, Calystegia soldanella, Carex kobomugi, Elymus mollis, Lathyrus japonica and Zoysia macrostachya. Indicator species of Z. macrostachya, Linaria japonica, C. soldanella, I. repens, Carex pumila, Artemisia capillaris, Oenothera biennis, L. japonica and E. mollis in G. littoralis community was differential species of syntaxonomy. C. kobomugi, Z. macrostachya, E. mollis, Cynodon dactylon and L. japonica was the distribution in dryness sand and moisture sandyloam, I. repens, C. soldanella, L. japonica and C. pumila was the distribution in dryness sand. In coastal dune, I. repens, C. soldanella, Salsola komarovi and G. littoralis combined strength of the distribution, and sand of coast was typical of the habitat.

Glehnia littoralis Fr. Schmidt (Umbelliferae) is a short-lived herbaceous species that are mostly distributed throughout East Asia. Although G. littoralis has been regarded as ecologically important one, there is no report on population structure in Korea. Starch gel electrophoresis was used to investigate the allozyme variation and genetic structure of Korean populations of this species. A high level of genetic variation was found in G. littoral is populations. Nine enzymes revealed 18 loci, of which 12 were polymorphic (66.7%). Genetic diversity at the species and population levels were 0.159 and 0.129, respectively. The sexual and asexual reproduction, high fecundity, and colonization process are proposed as possible factors contributing to genetic diversity. An indirect estimate of the number of migrants per generation (Nm = 1.45) indicated that gene flow was not extensive among Korean populations of this species. It is suggested that the ability of vegetation and artificial selection may have played roles in shaping the population structure of this species. we recommend that a desirable conservation population should be included at least 30 plants per population and especially those with high variation.

This study was carried out to investigate the distribution and habitat feature of Glehnia littoralis as a part of establishment of conservation plan for important natural agro-plant resources in South Korea. Habitat of Glehnia littoralis was generally found 28.2 m from high tide water line and 2.7 m above sea level at sand dunes near three seashore areas. Density and coverage of Glehnia littoralis were higher in east seashore among three seashore areas. The number of plant species growing with Glehnia littoralis in natural habitat was found 35 species. Among 35 species Ixeris repens Carex pumila, Carex kobomugi, Elymus mollis, Ischaemum anthephoroides, Imperata cylindrica var. koenigii were shown higher density and coverage. Average yearly precipitation and temperature of habitat for Glehnia littoralis were 1250.3 mm and $12.5^{\circ}C$, respectively. Among three seashores, the precipitation and temperature of south seashore were much more and higher than those of other two seashores. Soil characteristics of habitat for Glehnia littoralis were that average pH was 7.9 and organic matter was 0.23%. Content $P_2O_5$ and Ca were relatively higher, but the level K and Na were very low.

Bangpoong (防風) is a popular crude drug used to expel wind from the body surface (祛風解表) to remove dampness (勝濕). And to relieve pain (正痛) and spasm (正痙). In China and Japan, roots of Saposhnikovia divaricata (Turcz.) Schischk. Is used as Bangpoong. However, the roots of Peucedanum japonicum Thunb. Or Glehnia littoralis (A. Gray) Fr. Schmidt ex Miquel, being called Sikbangpoong (植防風) and Wonbangpoong (元防風) respectively are used instead of Bangpoong in Korea. The ITS regions of nuclear ribosomal DNA were analyzed to determine original plants and to design a molecular identification method for the crude drugs used as Bangpoong in Korea and China. It is demonstrated that RFLP analysis via PCR has the great potential as a novel tool to test crude drugs for the quality control and standardization.
