${\alpha}$-Curcumene is one of the physiologically active components of Curcuma zedoaria, which is believed to perform anti-tumor activities, the mechanisms of which are poorly understood. In the present study, we investigated the mechanism of the apoptotic effect of ${\alpha}$-curcumene on the growth of human overian cancer, SiHa cells. Upon treatment with ${\alpha}$-curcumene, cell viability of SiHa cells was inhibited > 73% for 48 h incubation. ${\alpha}$-Curcumene treatment showed a characteristic nucleosomal DNA fragmentation pattern and the percentage of sub-diploid cells was increased in a concentration-dependent manner, hallmark features of apoptosis. Mitochondrial cytochrome c activation and an in vitro caspase-3 activity assay demonstrated that the activation of caspases accompanies the apoptotic effect of ${\alpha}$-curcumene, which mediates cell death. These results suggest that the apoptotic effect of ${\alpha}$-curcumene on SiHa cells may converge caspase-3 activation through the release of mitochondrial cytochrome c.

Polysaccharides were isolated with alkaline extraction method from twelve pharmaceutical plants, which have been used against the various tumors in the oriental herb medicine, and examined for their antitumor activities. When the polysaccharides were administered i. p. at the dose of 10mg/kg/day for ten consecutive days to the male ICR mice, which had been implanted with $1{\times}10^{6}$ cells of sarcoma 180 twentyfour hours before the first injection of polysaccharides, those from Forsythia Corea, Curcuma, Zedoaria, Albizzia Julibrissin, Prunuts Persica, Foeniculum Vlugare and Daphne Pseudogenkwa showed inhibition ratios of 88.0%, 61.1%m 73.0%, 72.8% 55.1% and 71.7%. The significant prolongation of life span was observed only in the case of Forsythia Corea (18.1%). Other six polysaccharide fractions from Olibanum, Lonicera Japonica, Rheum Coreanum, Scirpus Maritimus, Gleditchia Officinalis and Brassica Juncea showed negligible inhibition ratios.

The Chinese traditional medicine Curcuma zedoaria (Zingiberaceae) has been proven to have a potent anti-inflammatory, antioxidant, and anticarcinogenic effects. A sesquiterpene, ar-turmerone, is isolated from Curcuma zedoaria. We have investigated the cytotoxic effect of ar-turmerone on K562, L1210, Jurkat, U937, Siha, RBL, and SNU cell lines by MTT assay.(omitted)

The aim of this study is to evaluate the effect of yeast extract (YE) and salicylic acid (SA) on the expression of curcuminoid-biosynthesis genes (CzDCS and CURS1-3), and accumulation of curcumin in Curcuma zedoaria cell cultures. The results showed that, in cells treated with YE or SA, the expression levels of curcuminoid genes were 1.14- to 3.64-fold higher than the control (untreated cells), in which the YE exhibited a stronger effect in comparison with SA. Curcumin accumulation also tended to be similar to gene expression, curcumin contents in YE- or SA-treated cells were 1.61- to 2.53-fold higher than the control. The SA treatment at the fifth day of culture stimulated the curcumin accumulation and expression in all four genes compared to that at the beginning. While the YE treatments gave different results, the CzCURS1 and CzCURS3 genes were expressed strongly in cells that were treated at the beginning. However, the CzDCS and CzCURS2 genes showed the opposite expression pattern, they were activated strongly in the treatments at day five of the culture. However, the content of curcumin reached its maximum value on the fifth day of culture in all investigations.

DNA damage induced by reactive oxygen species (ROS) seems to play an important role in the induction of mutation and cancer. Hydrogen peroxide $(H_2O_2)$ has been shown to induce a variety of genetic alterations, probably by the generation of hydroxyl radicals via Fenton reaction. In this study, we examined the ability of medicinal herbs in the suppression of $H_2O_2$-induced mutagenesis. Human fibroblast GM00637 cells were treated with $H_2O_2$ in the presence or absence of medicinal herbs, and $H_2O_2$-induced mutant frequency was measured at the hypoxanthine guanine phosphoribosyl transferase (HPRT) locus. Treatment of cells with various doses of $H_2O_2$ caused a significant increase of the HPRT mutant frequency. However, pretreatment of cells with several medicinal herbs reduced $H_2O_2$-induced mutant frequency. The strong antimutagenic effects were observed from the methylene chloride and ethyl acetate fractions of Selaginella tamariscina, Panax ginseng, and Angelica acutiloba; ethyl acetate fractions of Rehmania glutinosa, Leonurus sibiricus, Curcuma zedoaria and Commiphora molmol; butanol fractions of Scutellaria barbata, Tribulus terrestris, Curcuma zedoaria, Cyperus rotundus and Carthamus tinctorius, which were more than 60% inhibition of $H_2O_2$-induced mutant frequency at the HPRT locus.

Collected germplasms of five representative species belonging to Curcuma genus (C. longa, C. aromatica, C. zedoaria, C. phaeocaulis and C. kwangsiensis) were 52 samples from different farmhouse in Korea and China. To elucidate the genetic diversity among the species, 52 samples were analyzed by genomic fingerprinting method using amplified fragment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 643 total DNA fragments and 349 polymorphic bands with the 54.3% ratio of polymorphism. In the analysis of coefficient similarity using unweight pair group method with arithmetic averages (UPGMA), 52 Curcuma germplasm lines were ranged from 0.60 to 0.99 and clustered distinct five groups according to the species and collected geographical levels. However, the result of principal coordinate analysis (PCA) by multi-variate analysis was shown significantly greater differences among species than geographical origins based on AFLP profiling data of these samples.

Objective: We examined the antimetastatic effect of Curcuma zedoaria Roscoe (CZ) on pulmonary metastasis of B 16 cells. Methods: For 6 weeks, Zedoariae Rhizoma made from dried CZ were dissolved in distilled water and administered to mice 2 weeks before they were injected with B]6 melanoma cells. Mice were given CZ at doses of 250 and 500 mg/kg, and were compared for lung weight, survival days, and NO production. Results: Intake of CZ throughout the experiment extended the average survival time. Intake after B16 cell injection slightly prolonged survival time, but intake before B]6 cell injection did not influence life span. We examined the effect of CZ on macrophage function by measuring NO production. After the macrophages were given CZ for 6 weeks, the amount of NO generated by the macrophages stimulated with LPS in culture medium increased. NO generated by the macrophages also served as a cytotoxic factor against B16 melanoma cells. B16 melanoma-conditioned medium reduced NO production by macrophages. However, CZ treatment reversed the reduction in NO production by the conditioned medium significantly. Conclusion : These findings may suggest that macrophage function-modulating activity by CZ appears to underlie its antimetastatic activity, which leads to a decrease in the number of lung metastatic surface nodules and the extension of life span.

The possible effeets of some oriental herbs, whleh have been used to treat eaneerllke dllleue In Korea, on growth and afIatonn production by Aspergillus parasiticus R-716 were investigated. Zedoaria rhizoma, Curcuma longa, Cyperus rotundus, Angelica gigas, Paeonia albiflora, Paeonia mountan, Atractylis ovata, and Pulsatilla koreana were extracted with chloroform. Among them the extract of paeonia mountan was remarkably effective on the growth inhibition, and Curcuma longa, Zedoaria rhizoma, Cyperus rotundus, Paeonia albiflora, Atractylis ovata also inhibited the growth. The ertraet of Atractylis ovata and Curcuma longa, also Inhibited the afIatoxin production but the others showed no effect at all or sometimes stimulated effect. With the addition of O.2ml extract of Atractylis ovata in 30ml SLS medium, the growth was delayed for about 2 days, and after 9 days, mycellum weight was 0.953g, and total afatoxin was reduced 5O%($792\mu\textrm{g}$)of that produced in the control($1547\mu\textrm{g}$). Aflatoxin per mycelium weight was decreased 32%($992\mu\textrm{g}$) of that produced in the control($1467\mu\textrm{g}$), but NADPH oxidase was higher as compared to the control. The extract of Atractylis ovata appeared to have a inhibitory effect on the growth and the aflatoxin production of Aspergillus parasiticus R-716.
