Curcuma longa possesses powerful antifungal activity, as demonstrated in many studies. In this study, the antifungal spectrum of Curcuma longa alcohol extract was determined, and the resulting EC50 values (mg/mL) of its extract on eleven fungi, including Fusarium graminearum, Fusarium chlamydosporum, Alternaria alternate, Fusarium tricinctum, Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium culmorum, Rhizopus oryzae, Cladosporium cladosporioides, Fusarium oxysporum and Colletotrichum higginsianum, were 0.1088, 0.1742, 0.1888, 0.2547, 0.3135, 0.3825, 0.4229, 1.2086, 4.5176, 3.8833 and 5.0183, respectively. Among them, F. graminearum was selected to determine the inhibitory effects of the compounds (including curdione, isocurcumenol, curcumenol, curzerene, β-elemene, curcumin, germacrone and curcumol) derived from Curcuma longa. In addition, the antifungal activities of curdione, curcumenol, curzerene, curcumol and isocurcumenol and the synergies of the complexes of curdione and seven other chemicals were investigated. Differential proteomics of F. graminearum was also compared, and at least 2021 reproducible protein spots were identified. Among these spots, 46 were classified as differentially expressed proteins, and these proteins are involved in energy metabolism, tRNA synthesis and glucose metabolism. Furthermore, several fungal physiological differences were also analysed. The antifungal effect included fungal cell membrane disruption and inhibition of ergosterol synthesis, respiration, succinate dehydrogenase (SDH) and NADH oxidase.

Zedoary (Curcumae Rhizoma, Ezhu), a Chinese medicinal herb, has been reported to show anticancer activity. This study aims to investigate the effect of zedoary oil (Ezhu You) on the proliferation of AGS cells which is one gastric cancer cell line.
The main ingredients of the herb were detected by GC-MS for herbal quality control. Cell viability was measured by MTT assay and cell proliferation was investigated by immunocytochemical staining for proliferating cell nuclear antigen (PCNA) protein. In addition, the cell cycle distributions were detected by flow cytometry with propidium iodine (PI) staining and the apoptosis rates were evaluated by flow cytometry with annexin V/PI double-staining. The morphological changes associated with apoptosis were observed by Hoechst 33342/PI double-staining. Protein expression was determined by western blot analysis.
The main ingredients of the herb, including curzerene (26.45%), eucalyptol (12.04%), curcumol (9.04%), pyridine (7.97%), germacrone (7.89%), β-elemene (7.36%), τ-elemene (4.11%) and 28 other ingredients, including curdione, were consistent with the chemical profiles of zedoary. Zedoary oil significantly decreased the cell viability of AGS cells (P < 0.01) and MGC 803 cells (P < 0.01), and the inhibitory effects were attenuated by elevated concentrations of FBS. At high concentrations (≥90 μg/mL), zedoary oil killed GES-1 cells. At low concentrations (≤60 μg/mL), zedoary oil was less inhibitory toward normal gastric epithelial cells than gastric cancer cell lines. In AGS cells, zedoary oil inhibited cell proliferation in a dose- and time-dependent manner, with decreased PCNA protein expression in the zedoary oil-treated cells, and arrested the cell cycle at S, G2/M and G0/G1 stages after treatment for 6-48 h. At concentrations of 30, 60 and 90 μg/mL, which resulted in significant inhibition of proliferation and cell cycle arrest, zedoary oil induced cell apoptosis. In addition, Hoechst 33342/PI double-staining confirmed the morphological characteristics of cell apoptosis at 24 h. Zedoary oil upregulated the ratio of Bax/Bcl-2 protein expression (P < 0.01). Conclusions Zedoary oil inhibited AGS cell proliferation through cell cycle arrest and cell apoptosis promotion, which were related to Bax/Bcl-2 protein expression.

Curzerene is a sesquiterpene is isolated from the rhizome of Curculigo orchioides Gaertn with anti-cancer activity. Curzerene inhibits glutathione S-transferase A1 (GSTA1) mRNA and protein expression. Curzerene induces cell apoptosis.
