This study is part of research to develop the technology for managing major medicinal crops after harvest. We studied the optimal germination conditions of $Cynanchum$ $wilfordii$ (Maxim.) Hemsl. The mean germination time (MGT) of $C.$ $wilfordii$ seeds was higher after soaking for 4 days after storage at $5^{\circ}C$ for 8 weeks, than with germination at $25^{\circ}C$ (3 days). However, the germinative energy (GE) decreased as the number of days soaking increased. The greatest germination rate ($83.3{\pm}8.8%$) was at $25^{\circ}C$ with no soaking of seeds stored at $-20^{\circ}C$ for 8 weeks. Based on these results, we characterized the germination conditions of a major medicinal crop.

한약자원 약용부위와 대사체 수준에서 동등성이 규명된다면 식물조직배양을 통한 약용자원의 대량증식은 한약자원 약용부위의 보다 안전하고, 지속적인 대체 공급수단으로 활용이 가능하다. 따라서 본 연구에서는 기원 검증이 이루어진 백수오 약용부위와 동일조직에서 유래된 부정근으로부터 전세포추출물의 FT-IR스펙트럼 분석을 통해 대사체 수준에서의 동등성을 비교분석함으로써 한약자원 약용부위의 대체 공급수단으로 활용 가능성을 검증하고자 하였다. 식물생장조절제인 IBA 농도별 백수오 부정근의 생장률 분석 결과 5 mg/L IBA 첨가 배지에서 백수오 부정근 증식이 가장 우수하였다. SA 처리의 경우 처리 농도가 증가함에도 불구하고 백수오 부정근의 생장에는 차이가 없었지만, MeJA 처리시 농도가 높아질수록 부정근이 갈변되고 생장이 감소하였다. Elicitor 처리된 백수오 부정근 및 표준 약용부위 시료로부터 FT-IR 스펙트럼 데이터의 PCA 와 PLS-DA 분석결과 $400{\mu}M$ MeJA를 제외한 모든 처리구에서 백수오 기내 생산 부정근과 표준 약용부위 시료들 사이에서 전체 대사체 패턴이 매우 유사함을 알 수 있었다. 따라서 본 연구에서 확립된 FT-IR 스펙트럼기반 다변량통계분석 기술은 다양한 한약자원 약용부위 시료들의 대사체 수준 동등성을 신속하게 식별하는 수단으로 활용이 가능할 것으로 기대된다.

Flowery Knotweed Root is the dried tuberous root of the knotweed family wheres Auriculate Swallowwort Root is the dried tuberous root of the swallowort family. Flowery Knotweed Root is also called Red Flowery Knotweed Root in China, which is dried root of Polygonum multiflorum THUMB. Chinese Flowery Knotweed Root is better known as the dried tuberous root belonging to the family Apocynaceae whereas White Flowery Knotweed Root in Korea is the dried tuberous root of Cynanchum wilfordii(Maxim) Hemsl. Up to now, while the dried root named Red Flowery Knotweed Root has been widely used in China, Auriculate Swallowwort Root has been widely used in Korea. Both the roots contrast in a striking way with the origin, shape, botanical names, other names, and chemical constituents, so administration and dosage without discrimination of both sides can be open to question. According to the literature, it is recorded that Flowery Knotweed Root and Auriculate Swallowwort Root are similar to the characteristics, properties, and actions. From this study, the result is as follows: 1. Flowery Knotweed Root and Auriculate Swallowwort Root are divided into the family Apocynaceae and the family Polygonaceae, respectively. Accordingly 2. Flowery Knotweed Root is in shape of an irregular spindle and looks reddish- brown or deep reddish-brown and the section is light yellowish-brown, while Auriculate Swallowwort Root looks yellowish-brown and the section is white or yellow. 3. Flowery Knotweed Root is reported by the Journal of the Crude Drug that the medicinals have not the same therapeutic action as Auriculate Swallowwort Root. It is recorded that the properties, channel entry, functions of Flowery Knotweed Root and Auriculate Swallowwort Root in literature have much in common. Many works on the roots of this plant has been used traditionally as a tonic are required of. In view of the results, Flowery Knotweed Root and Auriculate Swallowwort Root varies both in nature and in shape, so that the administration and dosage of the medicinals must be taken a prudent attitude.
