지황은 국내 주요 약용작물 중 하나로, 크게 생지황, 건지황, 숙지황으로 나누어 용도에 맞게 이용된다. 본 연구에서는 시중에서 많이 이용되고 있는 4가지 육성품종에 대하여 이화학적 특성을 평가하고 숙지황에 가장 적합한 품종을 선발하고자 하였다. 본 실험에서는 지황 1호, 고강, 토강, 다강 총 4품종의 생지황을 이용하여 건조한 후, 막걸리에 담그는 작업부터 증숙 및 건조 작업까지를 1증으로 하여, 총 9회 반복하였다. 1증이 끝날 때마다, 산업적으로 중요한 요인 중 하나인 수율을 포함해 여러 이화학적 특성들을 평가하였다. 수율은 토강이 가장 높았고, 다강이 가장 낮게 나타났는데 이러한 수치들은 수분함량과 높은 부의 상관관계를 보였다. Fructose와 Glucose 함량은 초기에 일시적으로 증가하였다가 일정 시점 이후로는 감소하는 경향을 보였으며, Sucrose와 Raffinose, Stachyose는 점차 감소하다가 Raffinose, Stachyose의 경우, 4~5증 이후에는 검출되지 않았다. 유효성분인 Catalpol 함량도 모든 품종에서 4증 이후에는 검출되지 않았다. 반면 5-HMF 함량은 증숙이 진행됨에 따라 증가하였으며, 대한약전 기준인 0.1% 이상을 만족하였다. 지황 1호와 토강의 경우, 5증 이후 0.14%로, 타 품종에 비해 기준치에 빨리 도달하였다. 4가지 육성품종을 이용하여 숙지황을 제조하여 품질 특성을 평가한 결과, 전반적인 특성들을 종합적으로 고려하였을 때, 숙지황용으로는 토강이 상대적으로 수율이 높고 증숙시간도 짧게 소요되어 가장 적합할 것으로 보인다. 본 연구결과는 품종별 특성에 따라 산업적으로 적합한 용도로 활용하는 데에 유용한 정보가 될 것으로 생각된다.

Atractylodes japonica and Atractylodes macrocephala belongs to Atractylodes genus and theirs roots are used as 'Baek-chul'(White atractylodes rhizome) in Korea Pharmacopoeia. 'Baek-chul' widely used in traditional herbal remedies in Asia. Concurrently, the 'Baek-chul' demand enormously increased in the market due to the growing interest in favoring health benefits but it is depend on import from China. Thus we conducted breeding research to solve the problems associated with domestically cultivated 'Baek-chul' such as low productivity and low disease tolence. We crossed A. japonica (female parent) and A. macrocephala (male parent) in the greenhouse in September 2000. the next season 119 crossed line seeds were collected and germinated in the green house. Among them we selected the good lines in the same season. then conducted replicated yield trials (RYT) in 2014 to local adaptability test (LAT) in 2015-2016. The results showed that the 'AJM16' line has beneficial charactersitcs like, increased plant height, large rhizome diameter, narrow leaf width compared with a 'Sang-chul' (check cultivar) and varied flower color from A. japonica (female parent). The line 'AJM16' was also exhibited decreased anthracnose symptoms(Colletotrichum gloeosporides Penz.). Simultaneously the root yield of AJM16 was 2,409 kg per are, which was increased 130% higher yield compared to 'Sang-chul' (check cultivar) at three various regions from 2015 to 2016. Therefore, we named AJM16 as new cultivar 'Man-chul'. According the results, we have developed a new Atractylodes spp. hybrid cultivar 'Macn-chul' with high yielding and disease tolerance by National Institute of Horticulture and Herbal Science, RDA, in 2016.

A study was carried out to identify the life cycle of Adoxophyes orana (Lepidoptera: Tortrididae) that inflicts tea tree leaves in Korea and selected three ecofriendly pesticides (Common name for commercial: Essential oil, Nemacatch, and Wormstop in Korean Farmers' Market) of A. orana for pest control. A. orana appeared to follow four life cycle phases a year; each presenting varying developmental periods dependent on seasonal and environmental factors. The fecundity of A. orana female was $24.6{\pm}4.10$ for $1^{st}$, $36.7{\pm}12.77$ for$ 2^{nd}$, and $27.9{\pm}4.22$ for $3^{rd}$ phase during 2011, while it was $65.0{\pm}32.72$, $49.7{\pm}30.27$, $63.8{\pm}27.22$ for corresponding phases during 2012. The average longevity of adult A. orana was 7.72 days. The average number of eggs deposited by each female in this study group was 44.62 with an average of 2.47. In three selected ecofriendly pesticides, the mortality of A. orana on treating with the Essential oil [The essential oil of Chamaecyparis obtuse (100%)] and Nemacatch [Azadirachtin 800-900 ppm (75%)] were 36.67% and 43.33% after 3 days and were 48.30% and 56.67% after 7days, respectively. Besides, the mortality of A. orana on treating with Wormstop [Azadirachtin 500 ppm (5%) and Salannin+Liminoids (95%)] was 61.67% and 78.33% after 3 and 7 days, respectively. Therefore, the application of Wormstop was the most useful to control the diseases caused by A. orana.

In this study, we considered the usecase of formulas containing either Fritillaria Bulb (川貝母) or Fritillaria Thunbergii Bulb (浙貝母). These two medicinal materials are distinguished in the Korea Pharmacopoeia and circulating the market separately. But only term "貝母" is traditionally written for describing formulas, and the proper material will have to be determined by a subjective point of view. So, we have comparatively studied the nature, flavor, meridian entry, effect and indication of two materials first. Then we have chosen 54 formulas that "貝母" was used as a primary material from the Donguibogam and the Bangyachappyun, and we have compared effects, indications of two materials and indication of 54 formulas. Finally, we have suggested proper materials for each formula by referring the results above and sentences, which is explaining formulas and the roles of materials in the combination for treatment. The analysis showed that Fritillaria Bulb is proper to 15 formulas, Fritillaria Thunbergii Bulb is proper to 31 ones. This number is 85.2% of 54 formulas and this result shows that we need to distinguish between two materials for "貝母" in the formulas from old traditional literature. For the rest 8 formulas (14.8%), we could not analyze which material is proper or not.

Objectives : The application of polymerase chain reaction (PCR) for the discrimination of the herbal medicine Leonuri Herba (Leonurus japonicus) was evaluated by the comparison of the DNA sequence with Lamiaceae herbal medicine. Method : Genetic analysis showed that phylogenetic tree and comparing sequences through the DNA analysis of rbcL (ribulose-1, 5-bisphosphatecarboxylase) region and trnL-F (tRNA-Leu, trnL-trnF intergeni cspacer, and tRNA-Phe) region of chloroplast DNA from six Lamiaceae sold in market. And we developed IMCF and IMCR primers in order to distinction Leonuri Herba in six Lamiaceae using rbcL and trnL-F sequences. Results : Genetic analysis showed that six Lamiaceae showed individual group on phylogenetic tree. PCR amplification product of Leonuri Herba and another five Lamiaceae were developed for amplification of a 281 bp sequence and the specific PCR amplification of a 460 bp sequence that was exclusive to Leonuri Herba was designed using IMCF and IMCR primers. Conclusion : PCR analysis based on the chloroplast DNA sequences allows the discrimination of Leonuri Herba-based medicine.

Objectives : This study was designed to establish a characteristic discrimination of internal and external morphological standard of original plants and herbal states in Pogostemonis and Agastachis Herba. Methods : In this studies, the external-internal morphological standards were determined by using stereoscope and butanol series. Results : 1. The external characteristics: Pogostemon cablin has hairs and brown-like in stem, elliptical fruit. On the other hand, Agastache rugosa has no hairs and red-like in stem, obovatic trigone fruit. 2. The physical characteristics: Pogostemon cablin is gray in whole, has hairs in stem and numerous hairs of ash in leaf. On the other hand, Agastache rugosa is yellow-green in whole, has no hairs in stem. Specially the latter has deep-green colour and numerous hairs presenting mostly at lower epidermis in leaf. 3. The physical characteristics in currents: Pogostemon cablin is brown, has hairs and round-like stem. On the other hand, Agastache rugosa is green or yellow-green, has no hairs and tetragon in stem. 4. The internal characteristics: Pogostemon cablin has progressed spongy tissue in epidermal cell of leaf and many rank of epidermal cell in stem. On other hand, Agastache rugosa has I rank palisade tissue in leaf and few rank of epidermal cell in stem. In the external shape, it was possible that herbs were distinguished according to artificial cIassification and that same genus-degree of relatedness among herbs could be distinguished by more precise and active observation. In the shape of real herbs, I compared current herbs in market with original herbs which were just collected or were on the course of drying. In addition, it was possible that the internal shape could be identified by using microscope after butanol series. Conclusion : Though it was impossible to make distinction of herbs which are not current in my search contents, this search contents will be a standard for applying herbs in the future. An Additional standard establishment including physiochemical reaction and gene research is required in order to supplement the fault of this search.

Objectives: This study was conducted to explore the contemporary perception of traditional Korean medical doctors (TKMDs) on traditional Korean medicine (TKM) policies and issues. Methods: A questionnaire that included traditional medicine policy- and treatment-related issues was sent to 130 TKM medical centers and 4,300 TKM local clinical offices in Korea, and received responses from total 648 TKMDs in 122 TKM medical centers and 465 TKM local clinical offices. Results: Of the responding TKMDs, 40% believed that unification of Western and traditional medicines would benefit both modes of medical treatment, 67.6% were against allowing Chinese doctor certification to be effective in Korea through the Korea-China FTA (Free Trade Agreement), and 57.8% believed that the number of TKMDs should be reduced. We also found that 46.1% of TKMDs believed that more lectures on Western medicine would be needed in schools of TKM. Moreover, 87.5% of respondents regarded medical knowledge as necessary for treatment, and 49.4% believed National Certification Commission for Acupuncture and Traditional Medicine (NCCAOM) would be not necessary. TKMDs regarded governmental efforts as more vital than education in schools or individual efforts for enhancement of the traditional medical care market in Korea. To efficiently provide the advantages of complementary CAM, such as cost and safety, detailed research is required when policy is made. Conclusions: The TKM industry must implement policies how the relationship with Western medicine can be better defined under the current dual medical system. On the issue of human resources, more research will be needed on the current policy, which serves to maintain the status quo by blocking the importation of Chinese practitioners and by reducing the number of new practitioners.

For the quality control of traditional herbal medicine, Cinnamomi Ramulus, simultaneous determination of cinnamic acid, cinnamaldehyde, and 2-methoxycinnamaldehyde was established by using a high performance liquid chromatographic (HPLC) method with diode array detector. To separate three constituents, Eclipse XDB C18 ($5{\mu}m$, $4.6{\times}250mm$) was used with 0.1% acetic acid and acetonitrile. Validation of the chromatography method was evaluated by linearity, recovery, and precision test. Calibration curve of standard components showed excellent linearity ($R^2$ >0.9999). A simple and efficient method by HPLC was developed to evaluate the quality of traditional herbal medicines made from Cinnami Ramulus. Three major bioactive ingredients in 30 samples that are from China(8) and Vietnam(22) were separated and quantified.

본 실험은 수출과정 중 '화산' 배의 신선도를 유지하기 위한 목적으로 과실의 숙도별 적정수송온도 및 유통온도의 설정을 위하여 모의유통기간 중 과실의 품질과 생리장해 발생을 조사하였다. 만개 후 135일에 수확한 과실의 경우, 유통 30일에 조사한 과실 경도는 $1^{\circ}C$에 수송되고 $18^{\circ}C$에서 유통된 과실은 28.6N로 조사되었던 반면 $5^{\circ}C$에서 수송되고 $25^{\circ}C$에서 유통된 과실은 24.2N으로 수송 및 유통온도가 낮을수록 경도가 높게 유지되었다. 만개 후 145일에 수확한 과실의 경도는 만개 후 135일에 수확한 과실에 비하여 유통기간 중 경도가 현저하게 낮았는데 유통온도가 높을수록 과육의 경도 저하가 빠르게 진행되었다. 과실의 생리장해 발생을 측정한 결과, 수송온도와 관계없이, $25^{\circ}C$에서 유통된 과실이 $18^{\circ}C$에서 유통된 과실보다 과육의 생리장해 발생 및 과실 부패율이 2배 이상 높게 측정되어 수출과정 중 과실의 신선도 유지를 위해서는 유통온도의 관리가 보다 중요한 요인으로 작용하는 것이 확인되었다. 따라서 수출과정 중 발생하는 경제적 손실을 줄이고 고품질 과실의 유통을 위해서는 유통환경을 고려한 수확시기 조절 및 수송 유통과정에서의 철저한 온도관리가 필수적으로 판단된다.
