Korean wild and forest cultivated ginseng has long been accepted as high medicinal values compared to field cultivated ginseng. Owing to the high price of Korean wild ginseng, Chinese wild and forest cultivated ginseng were smuggled and sold as Korean wild and forest cultivated ginseng. Therefore, an efficient method is required to distinguish Korean ginseng from Chinese ginseng. Microsatellites, simple sequence repeats (SSRs), are highly polymorphic loci present in DNA that consist of repeating units of base pairs. Thus SSR markers are highly advantageous for detection of small genetic variances of intra-species. In the present study, we constructed a microsatellite-enriched genomic library from South Korean wild Panax ginseng. After sequence analysis of 992 randomly picked positive colonies, 126 (12.7%) of the colonies were found to contain microsatellite sequences, and 38 primer pairs were designed. By polymorphism assessment using 36 primer pairs, 4 primers (PG409, PG450, PG491, and PG582) were shown to be polymorphic to distinguish the South Korean ginseng from the Chinese ginseng. These 4 microsatellite markers will provide powerful tools to authenticate South Korean ginseng from Chinese ginseng.

The objective of this study was to investigate the perception of ginseng and ginseng products among university students living in Yeongsu, Ganwon-do. 196 university students participated in the survey for our study. The ginseng intakes of male students(59.1%) was significantly(p<0.05) higher than the intake of female students(40.9%). The primary reasons for consuming ginseng were to "Maintain my [one's] health" and to, "Restore my [one's] energy". The reasons for not consuming ginseng were "Taste" and, "Physical constitution". Consumers purchased the following ginseng products at the market: For males, ginseng wine(21.7%), ginseng beverage(17.4%), ginseng candy(17.4%) and ginseng kimchi(17.4%) for females, Korean ginseng snacks(23.3%), ginseng yogurt(20.9%), ginseng candy(14.0%), and ginseng jelly(11.6%).

In Korean ginseng, Panax ginseng C.A Meyer, it was difficult to isolate chloroplast DNA with classical methods, because of the high polysaccharide content of ginseng chloroplast The simple and efficient method of chloroplast DNA isolation from ginseng leaves has been developed by motificalion of recently advanced methods. Also, it can be successfully applied to ctDNA isolation of Chinese cabbage, radish, petunia tobacco as well as ginseng. Isolated chloroplast DNA from ginseng was digested with various restriction endonucleases. It was estimated that the molecular weight of Korean ginseng chloroplast DNA was about 142 kb. There was no difference in restriction endonuclease digestion patterns between two variants of Korean ginseng, which are Jakyung-Jong (violet-stem variant) and Hwang- sook-Jong (yellow-berry variant).

고려인삼과 미국삼을 공시하여 Panax속 종간의 원료수삼 및 홍삼 등급에 기초하여 품질을 평가분석하였다. 1. 미국삼은 고려인삼에 비하여 근중이 적고 부정형 지근이 동체에서 많이 발생하는 관계로 체형이 불량하였다. 2. 홍삼수율은 고려인삼이 30.4%,미국삼이 33.8%로 미국삼이 높았고 홍삼의 본삼수율은 고려인삼이 80.4%, 미국삼이 72.2로 고려인삼이 높았다. 3. 원료수삼 1등급은 고려인삼이 미국삼에 비하여 2배정도 많았으나 2등급은 미국삼이 고려인삼에 비하여 많았다. 한편 고급홍삼인 천지삼율은 고려인삼이 미국삼에 비하여 높았다. 4. 홍삼 품질의 저하 원인은 고려인삼 미국삼 모두 내공과 내백 발생에 있었고 특히 미국삼은 내공에 비해 내백이 3배 가량 많이 발생하였다. 5. 홍삼의 지별 분포에서 고려인삼은 20지 이상의 대편급이 많았고 미국삼은 20지 이하의 소편급이 많았다.

MicroRNAs (miRNAs) are a class of recently discovered non-coding small RNA molecules, on average approximately 21 nucleotides in length, which underlie numerous important biological roles in gene regulation in various organisms. The miRNA database (release 18) has 18,226 miRNAs, which have been deposited from different species. Although miRNAs have been identified and validated in many plant species, no studies have been reported on discovering miRNAs in Panax ginseng Meyer, which is a traditionally known medicinal plant in oriental medicine, also known as Korean ginseng. It has triterpene ginseng saponins called ginsenosides, which are responsible for its various pharmacological activities. Predicting conserved miRNAs by homology-based analysis with available expressed sequence tag (EST) sequences can be powerful, if the species lacks whole genome sequence information. In this study by using the EST based computational approach, 69 conserved miRNAs belonging to 44 miRNA families were identified in Korean ginseng. The digital gene expression patterns of predicted conserved miRNAs were analyzed by deep sequencing using small RNA sequences of flower buds, leaves, and lateral roots. We have found that many of the identified miRNAs showed tissue specific expressions. Using the insilico method, 346 potential targets were identified for the predicted 69 conserved miRNAs by searching the ginseng EST database, and the predicted targets were mainly involved in secondary metabolic processes, responses to biotic and abiotic stress, and transcription regulator activities, as well as a variety of other metabolic processes.
