Dendranthema spp are distributed in various regions in Korea. This report is the quantitative results of phenolic compounds on the 5 resources collected from all over the country. It was known that it has phenolic compounds, as an anticoagulant activities and immunoadjuvant activity of contribute to the cardiovascular effects. This was used for quantitative analysis of chlorogenic acid(CA), 3,5-Dicaffeoylquinic acid(3,5-DCA), 4,5-Dicaffeoylquinic acid(4,5-DCA) and linarin, with UPLC-PDA and LC-IT-TOF-MS. Extraction efficiency of compounds was compared by using ultrasonic extraction and reflux extraction with different extraction conditions (methods and time). In 50% MeOH extracs (30 mins) of Dendranthema zawadskii (Herb.) Tzvelev (SDZ), Dendranthema zawadskii var. yezoense (Maek.) Y.M.Lee & H.J.Choi (NDZ), Dendranthema zawadskii (Herb.) Tzvelev var. teuisectum (Kitag.) J. H. Pak (GDZ), Dendranthema careanum (H. $L{\acute{e}}v$. & Vaniot) Vorosch. (HDC) and Dendranthema zawadskii var. tenuisectum Kitag (PDZ), chlorogenic acid contents were 1.14‰, 6.95‰, 7.27‰, 1.47‰ and 2.64‰, 3,5-dicaffeoylquinic acid contents were 3.30‰, 5.60‰, 10.81‰, 2.67‰ and 1.50‰, 4,5-dicaffeoylquinic acid contents were 0.74‰, 1.93‰, 3.36‰, 0.61‰ and 0.43‰ and linarin contents were 3.90‰, 10.15‰, 0.15‰, 0.73‰ and 0.21‰, respectively.

Dendranthema boreale and D. indicum are easily distinguished from other Korean Dendranthema spp. by having yellow flowers. We have found a putative new taxon of Dendranthema having white flowers, except for sharing most characters with Dendranthema boreale. The chloroplast (cp) genome of the putative new taxon of Dendranthema, Dendranthema sp. K247003, registered in National Agro-Biodiversity Center (ABC), was completely characterized as a genetic barcode. The cp-genome of Dendranthema sp. K247003 was 151,175-bp in size: LSC was 82,886-bp, IR 24,971-bp, SSC 18,347-bp. The cp-genome of Dendranthema sp. K247003 contains 113 genes and 21 introns consisted of 79 protein coding genes, 4 RNA genes, and 30 tRNA genes, with 20 group II introns and one group I intron. Some of the genes and there introns were duplicated in IR. The cp-DNA of Dendranthema sp. K247003 is distinguished from that of D. boreale IT121002 by 67 SNPs in genic regions of 24 protein coding genes and by a 9-bp INDEL in ycf1. Further cp-DNA study will give us better information on genetic markers of Dendranthema species.

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.
