Abstract
In order to industrialize of Dendranthema indicum (L.) DesMoul., which is a lot of commercially available and is synonymous with chrysanthemum tea, in the autumn of 2018, Dendranthema indicum (L.) DesMoul. seeds were collected from its own native region, and the seeds were germinated after refrigerated storage. Young seedlings were subjected to experiments in February, March, and April in the open field to examine the effects on the harvesting of leaves by distance and the growth of leaves and stems. The results of analyzing the components by collecting the leaves+stem after collecting the flower of Dendranthema indicum (L.) DesMoul. are as follows. 1. When D. indicum (L.) DesMoul. seedlings were planted according to the transplanting date, the number of flowers was 17.1 in the transplanting date in April. The diameter of the flower was 2.9cm, 16ea, 6.5~6.6g in the fresh weight, and the dry weight of the case was 1.1~1.2g. The leaves were 46~47ea in March and April in the planted area, 5.2~5.3cm in leaf length and 3.5~3.6cm in leaf width. 2. When planted D. indicum (L.) DesMoul. seedlings according to transplanting distance, the number of flowers was 16.2 when planted at 20×20cm intervals and, 16.8~17.1 at 30×30~50×50cm intervals. The diameter of the flower was 2.7~2.8cm, the number of petals was 8, the length of the petal was 0.8 cm, and fresh weight was 6.5~6.6g per flower. Leaves had the largest number of 47 of 30×30cm and 40×40cm, and leaf length appeared at the longest 6.2cm in the 50×50cm treatment area, but 5.2cm in the other treatment areas. 3. The extraction yield of D. indicum (L.) DesMoul. leaves+stems was 7.93%, and the extraction solvent colors were light green at 50, 60% and green at 70, 80, 90, 100%. The extraction yield of D. indicum (L.) DesMoul. flowers was 7.58%, the color of the extraction solvent was light yellow at 50, 60 and 70%, yellow at 80 and 90%, and dark yellow at 100%. 4. We confirmed 11 kinds of ingredients such as in D. indicum (L.) DesMoul. flowers are gallic acid, 4-hydroxy benzoic acid, methyl gallate, 4-hydroxy-3-methoxy benzoic, caffeic acid, salicylic acid, p-coumaric acid, sinapic acid, naringin, 4-melthoxyben, flavone. The content was 29.200-36.900ppm. 5. The components contained in the D. indicum (L.) DesMoul. leaf+stem, salicylic acid appeared at 6,129.526ppm, and the next 4-methoxyben was 1,966.714ppm. It was methyl gallate 8.197ppm, 4-hydroxy-3-methoxy benzoic 6.994ppm, caffeic acid 5.566ppm, flavone 4.522ppm, p-coumaric acid 3.787ppm, gallic acid 1.893ppm that appeared in the content below 10ppm.
시중에서 많이 판매되는 국화차의 대명사인 감국(Dendranthema indicum (L.) DesMoul.)을 산업화하기 위해, 2018년 가을에 자생지에서 감국(Dendranthema indicum (L.) DesMoul.) 종자를 채취하여 냉장 보관 후 종자를 발아시켰다. 어린 묘종은 2, 3, 4월에 노지에 시기별, 간격별에 따른 꽃의 수확량과 잎, 줄기의 성장에 미치는 영향을 살펴보기 위한 실험을 하였다. 감국(Dendranthema indicum (L.) DesMoul.) 꽃을 채취한 후 잎, 줄기를 채취하여 성분을 분석한 결과는 아래와 같다. 1. 국화 묘종을 정식시기별로 심었을 때 꽃은 4월에 정식한 처리구에서 17.1개로 가장 많았다. 꽃의 지름은 2.9cm, 꽃수는 16개, 생체중은 6.5~6.6g, 건체중은 1.1~1.2g이었다. 잎은 3, 4월에 심은 처리구에서 46~47개, 엽장은 5.2~5.3cm, 옆폭은 3.5~3.6cm이었다. 2. 국화 묘종을 정식거리별로 심었을 때 꽃수는 20×20cm 간격으로 심었을 때 16.2개로 가장 작았고, 30~50cm 간격에서는 16.8~17.1개 이었다. 꽃 지름은 2.7~2.8cm, 꽃잎수는 8개, 꽃잎 길이는 0.8cm, 꽃 한 개의 생체중은 6.5~6.6g이었다. 잎수는 30×30cm, 40×40cm에서 47개로 가장 많았고, 엽장은 50×50cm처리구에서는 가장 긴 6.2cm로 나타났지만 그 외 처리구에서는 5.2cm이었다. 3. 국화 잎+줄기의 추출수율은 7.93%였고, 추출 용매색은 50, 60%는 연녹색, 70, 80, 90, 100%는 녹색으로 나타났다. 감국 꽃은 추출수율이 7.58%, 추출 용매색은 50, 60, 70%에서는 연노란색, 80, 90%에서는 노란색, 100%에서는 진노란색이었다. 4. 국화 꽃에 함유된 성분은 gallic acid, 4-hydroxy benzoic acid, methyl gallate, 4-hydroxy-3-methoxy benzoic, caffeic acid, salicylic acid, p-coumaric acid, sinapic acid, naringin, 4-melthoxyben, flavone 등 11가지 성분을 확인하였다. 함량은 29.200~36.900ppm이었다. 5. 국화 잎+줄기에 함유된 성분은 salicylic acid가 6,129.526ppm으로 나타났고, 다음으로 4-methoxyben 1,966.714ppm이었다. 함유량이 10ppm 이하로 나타난 것은 methyl gallate 8.197ppm, 4-hydroxy-3-methoxy benzoic 6.994ppm, caffeic acid 5.566 ppm, flavone 4.522ppm, p-coumaric acid 3.787 ppm, gallic acid 1.893ppm이었다.
