In recent years, research into medicinal herbs with antioxidative activities has increased. Chrysanthemum morifolium and Chrysanthemum indicum are aromatic herb plants and that have long been used in traditional Vietnamese medicine. This study aims to evaluate the chemical compositions and antioxidative activities of essential oils hydrodistilled from the flower heads of C. morifolium and C. indicum. The chemical compositions of the essential oils were compared using gas chromatography/mass spectrometry (GC/MS) analysis. The antioxidative activity was determined and evaluated spectroscopically by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, metal chelating activity, reducing power, and total antioxidant capacity assays. According to the GC/MS results, chrysanthenone was predominant in the essential oils of both C. morifolium (64.14%) and C. indicum (32.02%). This is the first report of the identification of chrysanthenone as a major constituent of the essential oil of C. morifolium. Both Chrysanthemum oils were also revealed to possess antioxidant potential, exhibiting high antioxidative activities. In particular, the DPPH radical scavenging activities of the C. morifolium and C. indicum oils at a concentration of 100 mg/mL were 76.9 and 83.2%, respectively. The metal chelating values of C. morifolium and C. indicum were 0.85 and 0.76, whereas the reducing power values of that at 100 mg/mL were 0.76 and 0.71, respectively. This study provides the chemical properties of the essential oils of both C. morifolium and C. indicum grown in Vietnam and their potential antioxidant capacity.

In this work, extraction and purification of the possible whitening agents from the Chinese plants; Chrysanthemum morifolium Ramat (xizang cai ju hua), Rhodiola sachalinensis, and Terminalia chebula Retzius have been described. The chopped leaves of Chrysanthemum morifolium Ramat and Terminalia chebula Retzius were added to water and ethyl ether, respectively. Components were separated on a GS310 column ($21.5{\times}500mm$ i.d., $10-15{\mu}m$) and concentrated into four or three portions. The chopped leaves of Rhodiola salientness were added to methanol and separated and concentrated on a column ($C_{18}$ column, $3.9^{\circ}$�F8;300 mm i.d., $15{\mu}m$) into two parts. The whitening effects of extracts were examined by in-vitro melanin production assay, in melana and B16 cells at a concentration of $10{\mu}g/ml$. The ethyl acetate layer of Chrysanthemum morifolium Ramat showed 92% melanin inhibitory at $200{\mu}g/ml$, the extract of Rhodiola sachalinensis showed a whitening effect of about 60% melanin inhibitory, which was more efficient than the whitening effect of arbutin (45.6%). The methanol extract of Terminalia chebula Retzius inhibited melanin expression by 90% at $100{\mu}g/ml$; however, it was toxic to B16 melanoma cells.

The flower of Chrysanthemum morifolium Ramat. with antioxidant, anticancer, and anti-inflammatory functions has been a widely used traditional herb as a healthy beverage and medicine. The aim of the present study was to investigate a herb tea consisting of C. morifolium Ramat., Corni fructus and Schizandra chinensis Baillon for its hepatoprotective activity against $CCl_4$-induced toxicity in freshly isolated rat hepatocytes and antigenotoxic effect against oxidative stress induced DNA damage in human leukocytes. Three different compositions of the herb tea (Mix I, II, and III) were prepared by extracting with water at $90^{\circ}C$. Freshly isolated rat hepatocytes were exposed to $CCl_4$ along with/without various concentrations of each tea. Protection of rat primary cells against $CCl_4$-induced damage was determined by the MTT assay. The significant antihepatotoxic effect of the tea was shown in Mix I and II. The increased transaminase (AST and/or ALT) release in media of $CCl_4$ treated hepatocytes was significantly lowered by all the teas tested. The effect of the tea on DNA damage in human leukocytes was evaluated by Comet assay. All teas showed a protective effect against $H_2O_2$-induced DNA damage. From these results, it is assumed that herb tea based on C. morifolium Ramat., Corni fructus and Schizandra chinensis Baillon exerted antihepatotoxic and antigenotoxic effects.

This study describes an efficient and widely applicable droplet-vitrification following cryopreservation for shoot tips of Chrysanthemum morifolium (Ramat.) cvs. 'Borami' and 'Yes morning'. The shoot tips of Chrysanthemum were precultured in Murashige and Skoog (MS) liquid medium supplemented with sucrose (0.3-0.7 M). Precultured explants were treated with loading solution (LS, C6) containing glycerol 20% and sucrose 20% for 30 min and exposed to dehydration solution (B5) containing 40% of glycerol and 40% of sucrose for 60 min at $25^{\circ}C$, and then transferred onto droplets containing $2.5{\mu}l$ PVS3 on sterilized aluminum foils ($4cm{\times}0.5cm$) prior to direct immersion in liquid nitrogen (LN) for 1 h. The highest regeneration rate (%) was obtained when shoot tips were precultured with treatment-2 (exposing of shoot tips to MS + 0.3M sucrose for 30 h and then treated with MS+0.5 M sucrose for 16 h) at $25^{\circ}C$ in both the cultivars. The viability of cooled samples, followed by culturing on $NH_4NO_3$-free MS medium for first 5 days was increased to two-fold (80.7%) regrowth rate over those cultured on normal MS medium or MS medium containing plant growth regulators. This result shows droplet-vitrification would be a promising method for cryobanking chrysanthemum germplasm.

Objectives : Reactive oxygen species (ROS) are involved in a wide spectrum of diseases including chronic inflammation and cancer. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the extracts from the herbal teas such as Lonicera japonica Thunberg (L. japonica), Chrysanthemum morifolium Ramat (C. morifolium), Mentha arvensis L. (M. arvensis), and P.rhizoma. Methods : Anti-oxidant activity was evaluated using DPPH radical scavenging assay and $Fe^{2+}$ chelating assay. And DNA cleavage assay was performed to evaluate an anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell line. Results : L. japonica scavenged DPPH radical by 9.8% at 12.5 ${\mu}g/ml$, 24.8% at 25 ${\mu}g/ml$, 34.3% at 50 ${\mu}g/ml$, 61.1% at 100 ${\mu}g/ml$ and 75.8% at 200 ${\mu}g/ml$, respectively. In addition, C. morifolium and M. arvensis removed DPPH radical by 15.6% and 10.4% at 12.5 ${\mu}g/ml$, 34.8% and 22.8% at 25 ${\mu}g/ml$, 66.9% and 43.3% at 50 ${\mu}g/ml$, 87.4% and 69.1% at 100 ${\mu}g/ml$, and 92.1% and 73.2% at 200 ${\mu}g/ml$, respectively. However, P. rhizoma did not affect on DPPH radical scavenging. The $Fe^{2+}$ chelating activity was highest in L. japonica, but lowest in P. rhizoma among the herbal teas. In addition, the extracts from L. japonica, C. morifolium and M. arvensis inhibited oxidative DNA damage via its anti-oxidant activity. In anti-inflammatory effect, the extracts from C. morifolium inhibited NO production. In addition, it suppressed the $NF-{\kappa}B$ signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, this study indicates that L. japonica, M. arvensis and C. morifolium possess the protective effect against the oxidative DNA damage. Furthermore, C. morifolium exerts an anti-inflammatory effect.

Chrysanthemum morifolium (C. morifolium) is a perennial plant herb widely distributed in Korea and has been used in a traditional herbal remedy for various diseases. This study was conducted to determine antioxidant activities and antigenotoxic effect in water, acetone, ethanol and methanol extracts from white and yellow C. morifolium flowers (WC and YC). The antioxidants properties were evaluated on the basis of total phenolic content (TPC), DPPH radical-scavenging activity (RSA) and superoxide dismutase (SOD)-like activity. The highest TPC (5.09 g/100 g GAE) showed in YC methanol extract. The DPPH RSA activity of WC and YC water extracts increased as its concentration increase from 50 to 1000 mg/mL, respectively, and the lowest $IC_{50}$ of DPPH RAS showed in YC of $25^{\circ}C$. Also, WC solvent extracts showed significantly higher DPPH RSA than YC solvent extracts. The SOD-like activity of YC water extracts were higher than WC water extracts. And, YC acetone extract and WC methanol extract showed significantly higher SOD-like activity than WC acetone extract and YC methanol extract, respectively. The antigenotoxicity of WC and YC extracts were determined by measuring inhibitory effects of $H_2O_2$ induced DNA damage in human leukocytes using the comet assay, resulting that the ethanol extracts of WC and YC showed a significant antigenotoxic effect against oxidative stress. These results suggest that C. morifolium has significant antioxidant activity and protective effect against oxidative DNA damage.
