  • In this study, we evaluated the anti-oxidative, anti-wrinkle and whitening effect of Duchesnea indica (Andr.) Focke extract. Duchesnea indica (Andr.) Focke was extracted by two different solvents which were n-hexane and ethyl acetate. The anti-oxidant activity was measured by free radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl radical). And the inhibitory activities of tyrosinase for whitening effect and collagenase for anti-wrinkle were investigated. For anti-oxidant activity and whitening activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract showed more significant activity than n-hexane fraction of Duchesnea indica (Andr.) Focke extract. For anti-wrinkle activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract exhibited strong inhibition effects compared with reference. Therefore, Duchesnea indica (Andr.) Focke extract may be useful as a new antioxidant and anti-aging agent.

  • Objectives: The aim is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on colon cancer cells. Materials & Methods: Colo201 human adenocarcinoma cells were obtained from American Type Culture Collection. The boiled extract of Duchesnea indica(Andr.) Focke was added (10 and 20 microliters) to cultures and observed at 0, 6, and 12 hours, and at 12-hour intervals thereafter. Morphological changes in colon cancer cells were observed through an inverted microscope, Destruction of colon cancer cells was measured through Trypan blue exclusion testing. Suppression of the viability of colon cancer cells were measured via MTT assay. Anti-cancer mechanisms in the cell cycle of colon cancer cells were analysed via flow cytometry. Results: After introduction of Duchesnea indica(Andr.) Focke to cultures several changes were seen. Significant atrophy of the nucleus and cytoplasm of colon cancer cells was observed, indicating cell injury. Destruction of colon cancer cells was observed in direct proportion to dosage and duration. Suppression of viability of colon cancer cells for each test group was greater than that of the control group increasingly over time(36h, 48h, 60h, 72h), which was statistical significant (p<0.05). Cell numbers of the mitosis phase of the colon cancer cell cycle reduced. Conclusions: Statistcally significant anti-tumor effects of Duchesnea indica(Andr.) Focke were observed in this in vitro experiment. Results support a role for Duchesnea indica(Andr.) Focke in treatment of colon cancer. though it will required progressive research to develop a practical treatment.

  • Background : Death by cancer, malignant tumor, is on the increase around the world. In South Korea, cancer is the number one cause of death, and, in South Korea, stomach cancer is the most common form of cancer. This may be due to genetic and enviornmental factors. Because stomach cancer is so prevalent here, this study was undertaken. Objectives: This study was conducted to investigate the anti-cancer effects of Duchesnea indica(Andr.) Focke. in human stomach cancer cells(KATOIII). Materials & Methods: For human stomach cancer cells KATO III cells were obtained from Korea Cell Line Bank. The water decoction of Duchesnea indica(Andr.) Focke was added to cultures. First, morphological changes were examined under an inverted microscope. The destruction of stomach cancer cells was measured through Trypan blue exclusion testing, and suppression of viability of stomach cancer cells was measured via MTT assay. Anti-cancer mechanisms were assessed by analyzing the cell cycle. Results & Conclusions : In morphologic change, stomach cancer cells showed the withdrawn and floating appearance that is typical in cellular impairment. In each test group more stomach cancer cells were killed than in the control group to a statistically significant degree. Each test group showed more suppression of viability of stomach cancer cells than that of the control group to a statistically significant degree. Analysis of the cell cycle showed that Duchesnea indica(Andr.) Focke inhibited division of stomach cancer cells. This experiment yielded empirical evidence for Duchesnea indica(Andr.) Focke as a statistically significant anticarcinogen, specifically against stomach cancer.

  • Objectives: The aim of the experiment is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on stomach, liver, urinary bladder, prostate and kidney cancer cells. Materials & Methods: For cancer cells, AGS stomach, Hep3B and Hep3G2 liver, HT-1197, HT-1376 urinary bladder, PC3 prostate, and A-704 kidney cancer cells, all obtained from Korean Ce 11 Line Bank, were used. The boiled extract of Duchesnea indica(Andr.) Focke (10 and 20 microliters) was injected into cultures, and the cultures were observed at 0, 6 and 12 hours, and from then on at 12 hours intervals up to 72 hours. The destruction of stomach, liver, urinary bladder, prostate and kidney cancer cells were measured through Trypan blue exclusion testing. The suppresion on viability of stomach, liver, urinary bladder, prostate and kidney cancer cells was measured via MTT assay. Anti-cancer mechanisms were assessed by analyzing the cell cycle. Results: In morphologic change, AGS, Hep3B, HepG2 showed the withdrawn and floating appearance that is typical in cellular impairment. The destruction of AGS, HT-1197, HT-1376, A-704, PC-3, Hep3B and HepG2 cancer cells in each test group was greater than that in the control group to a statistically significant degree. The suppression on viability of AGS, HT-1197 and Hep3G in each test group was greater than that in the control group to a statistically significant degree. Analysis of the cell cycle after injection of D... Focke showed inhibition of cell division in all test groups(AGS, Hep3B, HepG2, HT-1197, HT-1376, PC3, A-704). Conclusions: The results of this experiment suggest that Duchesnea indica(Andr.) Focke has statistically significant anti-tumor effects on stomach, urinary bladder, kidney, prostate and liver cancer, of which stomach and liver cancer are prominently significant. This in vitro experiment supports a role for Duchesnea indica(Andr.) Focke as a potential cancer treatment, but progressive research on Duchesnea indica(Andr.) Focke and its anti-tumor effects is needed to develop a practical application for it in cancer treatment.

  • This study was conducted to further purify and characterize a polysaccharide fraction from whole parts of Duchesnea indica (Andr.) Focke, which was previously reported to show an antitumor activity by us. Mild acid-treatment of the fraction by 5% acetic acid yielded three subtractions (Fr. A,B and C) on a Sephadex G-25. Fr. A was composed of uronic acid, hexose, pentose and phenolic substance, Fr. C mainly phenolic substance, and Fr. B contained hexose. All three fractions exhibited colony stimulating factor activity.

  • This study was conducted to purify and characterize a polysaccharide fraction from whole parts of Duchesnea indica (Andr.) Focke, which was previously reported to show an antitumor activity by us. The plant was extracted with 5% ethanol for 3 days in the room temperature. The extract was dialyzed by 5% ethanol, and then concentrated by extraction with $excess\;_N-butanol$, followed by gel filtration named Fr. a and b. Each was composed of gallic acid, hexose, pentose, uronic acid and protein, indicating that both fractions were tannic polysaccharide containing protein. Heat treatment of them yielded gallic acid less polysaccharides. They showed a colony stimulating factor activity.

  • The whole plant of Duchesnea indica (Andr.) Focke (Rosaceae) which has been used in folklore in treating amenorrhea, inflammation, fever and traumatic injuries, in detoxifying and breaking up clots, was studied. The pharmacological test showed that the water extract had estrogenic and histaminergic actions, but no antiserotonin action. As a result of systematic separation in order to detect the active compounds revealing the estrogenic effect, the active compounds were found in the ether fraction. TLC of the ether fraction revealed 8 spots. Among them three major spots (Rf=0.54, 037, 0.31) were separated by preparative TLC. Some chemical properties of those major spots suggested that they were phenolic compounds, but that they were neither linoleic acid nor ${\beta}-sitosterol$ previously reported.
