Panax ginseng has been extensively used in the traditional oriental medicine as a restorative, tonic and Prophylactic agent. Recently, several reports regarding to anticancer effects of Panax ginseng has accumulated. These studies emphasized the fact that the anticancer activities might be due to a glycoside group called ginsenoside or pan.u saponin which has a water soluble characteristic. However, the authors and collaborates demonstrated that a highly lipid soluble component in extract of Panax ginseng roots contains a considerable cytotoxic activities against marine leukemic cells (L1210, P388) and human censer cells (HRT-18, HT-29, HCT48). This study was devised to observe the cytotoxic activities of Petroleum-ether extract of Panax giuseng roots (crude GBD and its Partially Purified fraction from silicic acid column chromatography (7 : 3 GX) against sarcoma-180 (5-180) and Walker carcinosar- coma 256 (Walker 256) in vivo, and murine leukemic Lymphocytes (L1210) and human rectal cancer cells (HRT-18) and human colon cancer cells (HT-29 and HCT48) in vitro. Each cell-line was cultured in medium containing serial concentration of the crude GX or 7 : 3 GX in vitro. A highly lipid soluble compound in the extract of Panax ginseng root was cytocidal to murine leukemic cells and human colon and rectal cancer cells in vitro. In the meantime, ginseng saponin derivatives did not have cytotoxic effects at its corresponding concentration. The growth rates of the cancer cells in medium containing ginseng extracts were inhibited gradually to a significant degree roughly in proportion to the increase of the extract concentration. The cytotoxic activity of 7 : 3 GX was about 3 times more potent than that of crude GX, one unit of cytotoxic activity against L1210 cells being equivalent to 2.54 Ug and 058 Ug for the crude GX and 7 : 3 GX, respectively. The Ri value of the active compound on silica- gel thin layer chromatography with petroleum-ether/ethyl ether/acetic acid mixture (90 : 10 : 1, v/v/v) as a developing so lvent was 053. While, the Panaxydol and Panaxynol as active compounds were purified from Petroleum-ether extract of Panax ginseng root by Drs. Ahn and Kim, and author found out that the one unit of cytotoxic activity of the Panaxydol and Panaxynol against L1210 cells being equivalent to 056 Ug and 0.3918 respectively. The survival times of mice inoculated with S-180 cells were extended about 1.5 to 2 times by the 7 : 3 GX treatment compared with their control group. The significantly decreased hemoglobin values of rats after inoculation with Walker 256 were recovered to normal range by oral administration of the crude Gt The synthetic levels of protein, DNA and RNA in human colon and rectal cancer cells were significantly diminished by treatment with the crude GX, which can explain a part of the origin of its anticancer activity.

The effects of rice hull (RH) powder on the anticarcinogenic activity of submerged-liquid cultures of Agaricus blazei Murill (AB) were assessed for mouse ascites cancers induced by mouse Sarcoma S-180 (S-180) cancer cells. Optimal growth of AB mycelia in the basal liquid culture medium, containing soybean meal, was achieved by culturing at $25^{\circ}C$ for 5 days, when evaluated by $\beta$-glucan content, Brix, and mycelial weight, relative to other culture conditions. Hot-water extract (HWE) of the submergedliquid culture of AB mycelia grown at $25^{\circ}C$ for 5 days exhibited a stronger anticarcinogenic activity, relative to HWE from other culture conditions. No such effects were obtained from AB mycelial cultures by alternative temperature-controlling cultures. Both cytotoxicity for S-180 cells and anticarcinogenic potentials for mouse ascites cancer of the HWE from AB mycelia grown in the basal medium containing 1% RH powder for 5 days at $25^{\circ}C$ were significantly (p<0.05) enhanced, relative to HWE from the AB mycelia culture of the basal medium without RH powder. These results indicate that HWE of submerged-liquid culture of AB mycelia, incubated in media containing 1% RH powder at $25^{\circ}C$ for 5 days, enhanced anticarcinogenic activity against S-180 cell-induced mouse ascites cancer, and suggest that RH powder is an excellent ingredient for the improvement of the anticarcinogenic potentials of the submerged-liquid culture of mushroom mycelia.

The low quality fresh ginseng was extracted by water at $80^{\circ}C$ and 240 bar for 20 min (HPE, High pressure extraction process). The cytotoxicity on human normal kidney cell (HEK293) and human normal lung cell (HEL299) of the extracts from HPE showed 28.43% and 21.78% lower than that from conventional water extraction at $100^{\circ}C$ in adding the maximum concentration of $1.0\;mg/m{\ell}$. The human breast carcinoma cell and lung adenocarcinoma cell growth were inhibited up to about 86%, in adding $1.0\;mg/m{\ell}$ of extracts from HPE. This values were 9-12% higher than those from conventional water extraction. On in vivo experiment using ICR mice, the variation of body weight of mice group treated fresh ginseng extracts from HPE of 100 mg/kg/day concentration was very lower than control and other group. The extracts from HPE was showed longer survival times as 35.65% than that of the control group, and showed the highest tumor inhibition activities compared with other group, which were 70.64% on Sarcoma-180 solid tumor cells. On the high performance liquid chromatogram (HPLC), amount of ginsenoside-$Rg_2$, $Rg_3$, $Rh_1$ and $Rh_2$ on fresh ginseng were increased up to 43-183% by HPE, compared with conventional water extracts. These data indicate that HPE definitely plays an important role in effectively extracting ginsenoside, which could result in improving anticancer activities. It can be concluded that low quality fresh ginseng associated with this process has more biologically compound and better anticancer activities than that from normal extraction process.

The current investigation was carried out to find out the anticancer activity of the methanol extract from Buplerum falcatum against cancered ICR mouse and cancer cell lines such as J774A.1 and L1210 cells. Extract of Buplerum falcatum displayed the considerable augmentation(134%) of the survival of ICR mouse bearing Sarcoma 180 cancer. In addition, the cytotoxic effects of methanol extract of Buplerum falcatum against J774A.1 cells and L1210 cells were found to show $IC_{50}$ values of $57.3\;{\mu}g/ml$ and $54.6\;{\mu}g/ml$, respectively. In contrast to such cytotoxicity against cancer cells, the extract exerted only meagre toxicity against normal lymphocytes. The increased generation of $O_2^-$ and the considerably increased activities of super-oxide dismutase(SOD) and glutathione peroxidase(GPx) of both J774A.1 cells and L1210 cells in the presence of Buplerum falcatum extract implied that the observed cytotoxicities may have resulted from the detrimental effect of reactive oxygen species(ROS) evoked by Buplerum falcatum extract on the cancer cells.

A methylotrophic Actinomycetes strain, which produce the anti-oral cancer activity compound, was isolated from soil and estimated as Amylocolatosis sp. based on taxonomic studies. A methanol didn't have influence on the production of the anticancer compounds. These compound were isolated by ethylacetate extract, silica gel column chromatography, sephadex LH-20 column and reverse phase HPLC. The compounds were very stable under heat ($121^{\circ}C$), acid(pH 2.0) and alkali(pH 11.0) treatment. The cytotoxic effect of isolated anticancer compounds on various cancer cell lines such as A549, SNU-1, KB, L1210, and Sarcoma 180 was investigated by MTT assay method. And these produced compounds also showed the broad antimicrobial spectrum to test strains such as bacteria and yeast.

New antitumor active polymers, poly(methacryloyl-2-oxy-1,2,3-propanetricarboxylic acid-co-exo-3,6-epoxy-l,2,3,6-tetrahydrophthalic acid) [poly(MTCA-co-ETAc)], poly(methacryloyl-2-oxy-l,2,3-propanetricarboxylic acid-co-hydrogen ethyl-exo-3,6-epoxy-l,2,3,6-tetrahydrophthalate) [poly(MTCA-co-HEET)], and poly(methacryloyl-2-oxy-l,2,3-propanetricarboxylic acid-co-a-ethoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil) [poly(MTCA-co-EETFU)] were synthesized and characterized. Their antitumor activity, inhibition of DNA replication and antiangiogenesis were examined. The structures of the polymers were identified by FT-IR, $^1H$ and $^{13}C$-NMR spectroscopy. The number average molecular weights of the fractionated polymers determined by GPC ranged from 9,400 to 14,900, and polydispersity indices were less than 1.7. The in vitro cytotoxicity of these polymers was determined and their antitumor activity was evaluated. The $IC_{50}$ values (the drug concentration at inhibition of 50% tumor growth) indicated that the synthesized polymers were much better inhibitors of cancer cells and showed lower cytotoxicity than the free 5-FU. The in vivo antitumor activity of the conjugates was examined using mice bearing the sarcoma 180 tumor cell line. The life spans (TIC) of the mice treated with the conjugates were higher than those treated with the free 5-FU. In addition, the synthesized conjugates showed excellent antiangiogenic activity based on an embryo chorioallantoic membrane assay.

Black chestnut (BC) was obtained through aging of fresh chestnut (FC) at 80℃ for 15 days. Proximate and mineral compositions along with colors of FC and BC were evaluated. With aging, moisture contents decreased by 50%, whereas sugar contents, carbohydrate contents, and calories increased. Contents of minerals (Fe, P, Ca, Na, Mg, K) were significantly higher in FC than in BC, showing an order of Mg < Ca < P < K in both FC and BC. Using a Hunter color system, it was found that lightness (L), redness (a), and yellowness (b) values of FC were higher than those of BC. Antioxidant and cytotoxic activities of hot water and ethanol (50, 80, 100%) extracts prepared from FC and BC were evaluated. Extraction yields were lower with FC than with BC. Among water and ethanol extracts, water extract showed the highest DPPH radical scavenging activity for both FC and BC. IC₅₀ values for ABTS+ radical scavenging activities increased after aging. Cytotoxicities of FC and BC extracts were similar to each other. They were different against various cell lines (3T3, HeLa, and Sarcoma-180). These results suggest that BC could be used as a new processed food using chestnut.
