The genus Polygonatum species belongs to the family Liliaceae which is widely distributed over areas of the north temperature zone. There are about forty more plants of Polygonatum species in the world widely distributed in eastern Europe and south east Asia. The plants of Polygonatum species have been used not only as ornamental plants but also for their medicinal values. This article is concerned with the specific properties and flavour of the drug and its history as a medicine, showing the main functional components of Polygonatum species of flavonoids, steroidal glycosides, and saccharides.

Germplasms having valuable characters are increasjngly important for modern breeding programs. This study was conducted to obtain the basic data for effective use of genetic resources of Polygonatum. The relationship of seven Polygonatum species collected widely in Korea was analyzed by RAPD markers. Total number of alleles amplified by nineteen random primers were 114 to 157, and variation in number of alleles was also diverse among seven species examined. The seven species were divided into two groups; one was of Polygonatum stenophyllum and Polygonatum humile. the other was of Polygonatum inflatum, Polygonatum lasianthum, Polygonatum odoratum var. pluriflorum (1), (2), and for variegatum.

An HPLC/Esl/MS method has been developed to identify and quantify the spirostanol glycosides in the rhizomes of five Polygonatum species. The relative distribution of two steroidal saponins in each extract was established using the selective ion monitoring (SIM) mode via an electrospray ionization (ESI) source. It was found that there were significant differences in the amount of spirostanol glycosides among the Polygonatum Species. The results showed that this method could be used to identify the steroidal saponins in the extracts and differentiate Polygonatum species with high sensitivity and reproducibility in a short time. Fragmentation patterns of the two reference compounds were also discussed with the electrospray ionization multi-stage tandem mass spectroscopy (ESI-MS$^n$).

Polygonatum taxa of Korea were classified as two sections, three series and 14 species and 2 varieties and reviewed taxonomically. Among the examined taxa, endemics in Korea were recorded as two species; P. grandicaule Y. S. Kim, B. U. Oh & C. G. Jang and P. infundiflorum Y. S. Kim, B. U. Oh & C. G. Jang. The habitat of Korean unrecorded species, P. acuminatifolium Kom. and P. odoratum var. odoratum were confirmed in this study. Keys to the sections, series and species including description of each taxon were provided here.

The phylogenetic relationship of Polygonatum species were examined by RAPD analysis. Polygonatum Rhizoma is called 'Whang-jung', and used Polygonatum sibiricum Redoute in defined as a source plant in Korean Pharmacopoeia. Polygonati Odorati Rhizoma is called 'Wui-yu', and P. odoratum Druce var. pluriflorum Ohiwi and related species are defined is source plants in Korean Herbal Pharmacopoeia. In UPGMA analysis, Polygonum was divided into two major groups. Polygonatum sibiricum and P. stenophyllum was placed in a cluster. On the other hand, P. falcatum A. Gray was included in the other cluster comprising. P. odoratum and related species, which are used as source plants for Polygonati Odorati Rhizome.

Polygonatum is a genus placed in the family Liliaceae, distributed throughout the Northern Hemisphere and 16 of the species are grown naturally in Korea. In oriental medicine, the rhizomes of Polygonatum have been used as two different medicines, Okjuk (Polygonati odorati Rhizoma) and Hwangjeong (Polygonati Rhizoma). However, it is difficult to identify the morphological and chemical differences between the medicinal groups and thus easy to confuse the one with the other. Therefore, a clear classification standard needs to be established so as to be able to discriminate between them. In the study, the morphological characteristics of the plants, Polygonatum spp., were examined. Then, the differences in SNPs among the DNA sequences of 7 of the Polygonatum spp. and 1 of the Disporum spp. were analyzed by DNA barcoding with rpoC1, rpoB2, matK, and psbA-trnH of the cpDNA region. In the results, three regions, rpoC1, rpoB2, and matK were useful for discriminating the species, P. stenophyllum and P. sibiricum. Furthermore, it was possible to discriminate the individual germplasm within the species by using the combination of the results obtained from rpoB2, rpoC1, and matK.

Rhizomes of Polygonatum species belong to Liliaceae are important herbal drugs in the traditional medical practice of Asian region. Two representative Chinese drugs derived from this genus are Hwangjeong and Okjuk. Though botanical origins of these drugs are officially listed as P. falcatum, P. sibiricum and P. kingianum for Hwangjeong and P. odoratum var. pluriflorum for Okjuk in the Korean Pharmacopoeia and Korean Herbal Pharmacopoeia, respectively, they are often sold as a mixture of several different species in the market.

This study was carried out to investigate vegetation structure and soil property of natural habitat of Polygonatum stenophyllum to provide basic information for propagation, conservation and restoration. Habitats of Polygonatum stenophyllum were classified into Hemiptelea davidii-Robinia pseudo-acacia dominant population (Yeongwol-eup), Pinus densiflora-Hemiptelea davidii-Callicarpa japonica dominant population (Nam-myeon), and Hemiptelea davidii-Rubus crataegifolius dominant population (Gangchon-ri). The soil pH 6.49~7.28; and electron conductivity 0.10~0.19 ds/m. The average content of organic matter, total nitrogen, available $P_2O_5$, $Ca^{2+}$, $Mg^{2+}$, $K^+$, and $Na^+$ were 8.24~16.45 g/kg, 0.02~0.13%, 45.67~123.67 mg/kg, 4.61~6.71 cmol(+)/kg, 0.17~0.63 cmol(+)/kg, 0.06~0.27 cmol(+)/kg and 0.03~0.30 cmol(+)/kg, respectively. Species diversity index (H'), maximum species diversity index (H' max), evenness (J') and dominance (1-J') of investigated sites ranged 1.0323 (Nam-myeon)~1.1134 (Yeongwol -eup), 1.4914 (Gangchon-ri)~1.6128 (Nam-myeon), 0.6401 (Nam-myeon)~0.7270 (Yeongwol-eup) and 0.2730 (Yeongwol-eup)~0.3599 (Nam-myeon) respectively.

The Polygonatum spp. used in this study was collected from 1994 to 1997, and planted by species in Hamyang medicinal plant experimental station field. $30{\sim}40 $ species of Polygonatum spp. have been known to be distributed in the northern hemisphere, and $14{\sim}18$ species in Korea. In this study, collected seven species of Polygonatum spp. were investigated. Plant height was highest in Polygonatum stenophyllum followed by P. falcatum, P. humile, P. lasianthum var. coreanum.. Leaf length was longest in P. falcatum and shortest in P. odoratum and leaf width was the most wide in P. odoratum var. pluriflorum. P. stenophyllum had 111 flowers per stem. The other species had $14{\sim}22$ flowers per stem. The ratio of flower setting in each species was high at two but was 95.2% at above four in P. stenophyllum. The number of fruits was 14.8, 15.4 and 17.7 in P. odoratum, P. falcatum and P. humile, respectively. Other species did not produce fruit. Fruit setting percentage was high in P. odoratum as 81.5%. The number of branched rhizome doubled every year.

Polygonatum species are a useful medical crop in Korea but basic study in the species was not well conducted. The study was carried out to analyse genetic diversity and intraspecific relationship of 47 Polygonatum species collected from Gyeongnam province. Their analysis was done through principle component analysis and average linkage cluster analysis with their twelve morphological traits. The result of principle component analysis showed the Prin 1, Prin 2 and Prin 3 represented 79% of total variation. By the 0.7 average distance of the cluster analysis and the calculated Euclidian distance, the 47 collected species were grouped into five groups. Group I included 22 collected species representing P. ordoratum var. pluriflorum, group II did 5 ones representing P. involucratum, group III was divided into two subclasses, 2 species including P. inflatum and 7 species including P. thunbergii, group IV also consisted of 2 subclasses, a species similar to P. thunbergii and P.involucratum, respectively, and finally group V included 8 species representing P.lasianthum var. coreanum. meaning that the useful germplasms can be collected from relatively small area.
