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.

Astilbe rubra (AR) is a perennial, belongs to the Saxifragaceae family, it contains tannin and triterpene. AR has been used in republic korea to improve toxication, fever, pain and convulsion. Recently, number of natural products have been analyzed for potential pharmacological activities including anti-cancer, anti-obesity and anti-diabetic medication. Consequently, we investigated the growth inhibition effect of Astilbe rubra water extract (WAC), ethanol extract (EAC) and bergenin on Hela cell (human adenocarcinoma cell). From whole plant of A. rubra, bergenin was isolated by column chromatography and its structures were identified by $^1H$, $^{13}C$ NMR and IT TOF-ESI MS. High extraction efficiency of bergenin was shown at 0.95% under 60 min reflux extraction with 50% MeOH. The MTS assay showed that EAC (ethanol extract) treatment increased cell death in a dose-dependent manner. Moreover, EAC treatment on Hela cell increased apoptotic cell death and caspase-3 activity. Results suggest that EAC has growth inhibition effect on Hela cells, but not WAC and bergenin. $500{\mu}g/mL$ EAC treatment inhibited Hela cell at $60.2{\pm}1.5%$.
