경북 영천군 고경면 작약 재배농가의 정식 4년차인 의성품종(Paeonia lactiflora Pall.)을 1993년 6월 17일 수확하고, 굵기가 27mm 이상인 뿌리를 선별하여 paeoniflorin 추출방법 및 HPLC 분석조건에 대한 조사결과를 요약하면 다음과 같다. 1. 초음파추출 및 환류추출법에 의한 작약근 추출물의 HPLC chromatogram은 상호간의 차이가 없었으며, 두 추출법 모두에서 paeoniflorin retention time이 10.2분대에 peak가 존재하였다. 2. 환류추출법에 의한 paeoniflorin 추출은 60min., 1회로 충분하였다. 3. 초음파추출에서 추출시간이 1hr.∼2hr. 까지의 paeoniflorin함량은 동일시간의 환류추출보다 각각 0.28%, 0.32% 낮게 평가되었고 3hr.∼4hr.의 추출에서는 두 방법간에 차이가 없었다. 4. 초음파 추출법은 분석작업이 용이함으로 다수계통의 상대적 비교시에는 환류추출법보다 효과적이다. 5. 작약추출물 중 paeoniflorin, albiflorin을 HPLC를 이용하여 분석할 때 높은 감도를 보이는 가장 효과적인 UV Detector 파장은 각각 240nm, 254nm이고, 동시정량시에는 254nm가 비교적 안정적이었다.

This study was conducted to investigate morphological characteristics of Korean local garlic varieties and to define the genetic variability and the correlations amongthe characters associated with yield. The plant height, the leaf sheath diameter, the nubmer of leaves, and bulb weight were significantly increased in the garlic plants from heavier seed bulbs. The proportation of six clove bulbs was more than 60% in Seosan variety and this was not realted with the number of cloves in seed bulb. While more than 70% bulbs in Jeoksung and Danyang varieties cultivated in paddy field were composed of 6 or 7 cloves, majority of the bulbs of Euisung and Danyang varieties cultivated in upland were composed of bulbs with 7 cloves or more. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed in bulb weight. GCV and PCV also showed high value in leaf sheath diameter. Thus, there is a greater scope for selection of these characters. The small difference between PCV and GCV values in plant height indicates that the environmental influence would be limited in this character. High heritability was observed of plant height (56.76%) and bulb weight (45.95%). And the weight per bulb (34.24%) exhibited highest genitic advance followed by leaf sheath diameter (18.8%) and plant height (9.61%), and those would be the ideal characters for selelction.
