This study was designed to establish the effects of Zingiber mioga, Zingiber mioga root and Zingiber ofiicinale on the lipid concentrations in hyperlipidemic rats. A total of 24 male Sprague-Dawley rats weighing 60$\pm$5g were fed one of four experimental diets for 4 weeks: a control diet (hyperlipidemic diet), diets supplemented with 3% of Z. mioga, 3% Z. mioga roots or 3% Z. officinale. The concentration of total cholesterol in serum was significantly decreased by 31% in Z. mioga group compared to the control group. The HDL-cholesterol concentration was significantly higher in Z. mioga and Z. mioga root supplemented groups than in control group. Triglyceride concentration in serum and liver significantly decreased with 3% Zingiber supplemented groups compared with control group, but had no significant differences among three Zingiber supplemented groups. The contents of total cholesterol triglyceride free cholesterol and cholesteryl ester in liver were remarkably lower in Zingiber supplemented groups than in control group. However, hepatic phospholipid level was not showed significant effect.

The purpose of this study was to confirm the possiblility of Zingiber mioga as a cosmetic material. For this we carried out biologically activated material characteristic evaluation about anti-oxidant, anti-inflammatory, wrinkle reduction effects using Zingiber mioga extract. To carry out this experiment, we extracted Zingiber mioga extract from Zingiber mioga flowers exract (ZMF) and Zingiber mioga leaves exract (ZML) with 70% ethanol. In order to evaluate the anti-inflammatory effect, we tested the toxicity and the hindrance activity to nitric oxide of samples using macrophages (RAW 264.7 cells). After we measured DPPH radical scavenging activity, ABTS+ radical scavenging activity and superoxide dismutase (SOD)-like activity of the Zingiber mioga extracts, we knew that they increased depending on their concentration. ZMF showed higher antioxidant activity than ZML after the measurement of ABTS+ radial scavenging activity and superoxide desmutase (SOD)-like activity. According to the measurement result of Nitric oxide inhibition activity we knew that ZMF reduced NO productions in a concentration-dependent manner. After the measurement of the biosynthesis quantity of pro-collagen type-1, we knew that its excellent effect appeared 110% or more at the concentration of 25 ㎍/ml. And at the same concentration, the result of the measurement of metalloprotease (MMP)-1 inhibition effect showed the 20% activation. In conclusion, ZMF is expected to be applied as a cosmetic material for wrinkle reduction. Zingiber mioga is believed to be used as a natural cosmetic material because it has been proven to have antioxidant, anti-inflammatory, and wrinkle-improving effects.

The chromosome number of myoga ginger (Zingiber mioga (Thunb.) Roscoe: Zingiberaceae) has been reported as 2n = 22 for Chinese plants and 2n = 55 for Japanese plants. We checked the chromosome number of Z. mioga in plants collected in Jeollabuk-do and Jeollanam-do, Korea, and counted 2n = 44, the first report of this number for the species. As the basic chromosome number of Z. mioga is thought to be x = 11, Z. mioga plants in China, Korea, and Japan appear to be diploids, tetraploids, and pentaploids, respectively. In finding the tetraploid race of Z. mioga in Korea, we can hypothesize that the pentaploid race in Japan is derived through the fertilization of reduced gametes of the diploid race and unreduced gametes of the tetraploid race.

Activate charcoal (AC) can be utilized as a soil conditioner in agricultural crop areas. This study was conducted to investigate the effect of AC on growth and yield of Zingiber mioga ROSC as affected by different amounts of AC. The results obtained are summarized as follows. Growth characteristics including plant height and leaf length were the highest when activated charcoal added with 10-30%, suggesting that optimum amount of activated charcoal was ranged from 10 to 30%. Growth and enlargement of the root were improved by 10% AC with higher rhizome length and weight.

The experiment was carried out to investigate the influence of rhizome size and mulching materials on some agronomic characters and flower-head yield of Gingiber mioga ROSCOE. The larger the size of rhizome was, the more the number of leaves developed, and the higher the yield was. The most suitable rhizome size for planting was found to be from I2cm to 15cm. Rice straw and polyethylene film mulching materials increased the soil porosity and reduced change of the soil moisture content. The yield of flower-head was highest in the straw-mulching plot, indicating that straw would be the best mulching material for growth and yield of flower-head in Gingiber mioga ROSCE.

Purpose: The purpose of this study was to investigate the stability of anthocyanin pigment extract from Yangha (Zingiber mioga ROSC). Methods: Yangha extract was investigated for the effects of metal ion, temperature, light, heating time, sugars, and organic acids on the stability of anthocyanin pigments. Results: Yangha pigment was more stable than other anthocyanin pigments at unstable temperatures. The stability of anthocyanin pigment significantly decreased one day after exposure to light. All tested sugars decreased the abundance of Yangha pigments, with highest levels in the presence of sucrose, and progressive decrease in the presence of maltose, fructose, glucose and galactose, in order. Among the organic acids tested, citric acid and malic acid were the most effective in stabilizing the Yangha pigment, followed by acetic acid and formic acid. Most metal ions except $Fe^{2+}$ were effective in stabilizing the pigment. Conclusion: These results provide useful reference data for the use of pigments from Yangha in processed foods.

In order to isolate antibacterial substances from the rhizome of Zingiber mioga Roscoe, the ethanol extracts was fractionated according to the activity against Bacillus subtilis, B. cereus and Staphylococcus aureus. Three antibacterial substances were isolated and purified by column chromatography and recrystallization. Compounds I and III showed activity against all the tested bacterias and compound II exhibited the activity against B. subtilis and B. cereus S. aureus. Compound I was examined antimicrobial activity against B. subtilis, B. cereus and S. aureus by optical density using Bioscreen C. Compound I showed strong growth inhibition at 10 ppm on B. subtilis and B. cereus for 72 hrs, and at 25 ppm on S. aureus. On the basis of spectrometric studies including $1^H-NMR$, ${13}^C-NMR$, DEPT, IH-lH COSY, HMQC, HMBC and IR, compounds I, II and III were identified as $(E)-8{\beta}(17)-epoxylabd-12-ene-15,16-dial\;(C_{20}H_{30}O_3,\;MW=318)$, galanolactone $(C_{20}H_{30}O_3\;MW=318)$ and galanal A $(C_{20}H_{30}O_3,\;MW=318)$, respectively. These results are the first reports on the isolation of $(E)-8{\beta}(17)-epoxylabd-12-ene-15,16-dial, galanolactone and galanal A from the rhizome of Zingiber mioga.
