The MeOH extracts from 21 species were tested for their cytotoxicity against SK-MEL-28 melanoma cell line and HaCat normal cell line in 5 g/ml by sulforrhodamine-B (SRB) method. Among them, the MeOH extract from Moutan Cortex Radicis showed the moderate activity with the growth rate of 74.3% in SK-MEL-28 cells and the high activity with the growth rate of 207.8% in HaCat cells. Activity-guided fractionation was performed and five compounds, paeonol (1), benzoylpaeoniflorin (2), benzoic acid (3), 2,5-dihydroxy-4-methoxy- acetophenone (4), paeonfliorin (5) were isolated from hexane and EtOAc fraction. The structures were established by physicochemical and spectrometric methods $(mp,\;UV,\;IR,\;^1H-NMR,\;^{13}C-NMR,\;spectram)$. All compounds were evaluated for their cytotoxicity, compound 4 showed the significant cytotoxic activity with $ED_50$ value of $5.92\;{\mu}g/ml$, but the other compounds no activity. These results suggest that compound 4 is a novel anticancer candidate against SK-MEL-28 melanoma cells.

The correlations between growth charateristics and root yield were investigated in 74 peony lines collected from chief producing place in Korea. Among these peony lines, single flower type was 61% and the rest were double type. And pink flower was in majority. Stem length, stem diameter and number of stem per plant were $50{\sim}60cm$, $7{\sim}8mm$ and $5{\sim}6$, respectively. Generally, disease tolerance and root yield were better in single flower type peonies than double type. Among single flower type peonies, the correlation coefficients between each characteristics and root yield were as follows : number of stem $(0.676^{**})$, number of roots $(0.646^{**})$, stem length $(0.617^{**})$, root diameter $(0.590^{**})$ and root length $(0.443^{**})$. Correlation between root yield and paeoniflorin content was highly significant $(0.383^{**})$ among single flower type peonies and significant $(-0.382^*)$ among double flower type peonies. Correlation between stem diameter and root yield was not significant (0.066).

Objectives To check marker content for appropriate quality control of Woohwangchungsimwon sterilized to ensure microbiological safety and to observe antioxidant activity for any changes in efficacy. Methods To measure any effects of sterilization on the effective compounds, 8 ingredients of Woohwangchungsimwon were screened for any changes in marker content using HPLC-DAD. Using the colorimetric method on the microplate reader any changes in total phenolic compound and flavonoid levels were observed. Antioxidant activity was measured using the DPPH, ABTS, and FRAP. Results Of the ingredients of Woohwangchungsimwon, 8 were subject to quantitative analysis before and after sterilization. 21.6 mg and 1.93 mg of Glycyrrhizin was found in Glycyrrhiza uralensis Fischer pre and post sterilization, respectively. Decursin found in Angelica gigas Nakai increased from 0.16 mg to 0.29 mg after sterilization. Bilirubin found in Gallstone of Bostaurusvar. domesticus increased from 0.24 mg to 0.33 mg. Cinnamic acid found in Cinnamomum cassia Blume increased from 0.02 mg to 0.05 mg. Ginsenoside Rb1 found in Panax ginseng C. A. Meyer decreased from 0.02 mg to 0.14 mg. Paeoniflorin found in Paeonia lactiflora Pallas increased from 1.05 mg to 1.13 mg. Amygdalin found in Armeniacae Amarum Semen increased from 2.68 mg to 2.83 mg. L-muscone found in Musk increased from 0.63 mg to 0.76 mg. As for total phenolic compound and total flavonoid content, there was a 1.22 and 4.15-fold increase. DPPH and ABTS increased by 20.45% and 20.69%, respectively. FRAP activity was 2.78 times more active post stabilization. Conclusions This study confirmed that high temperature high pressure steam sterilization, a method used to ensure microbiological safety of Woohwangchungsimwon, does not affect marker content; in other words, does not affect quality of the Woohwangchungsimwon. It could also be seen that total phenolic compound and flavonoid content increased after sterilization. An antioxidant activity test showed that there was significantly increased activity of antioxidants.
