  • This study was performed to determined the antioxidant activities, anticancer and immuno-activities of anthocyanin fraction from Rubus coreanus Miquel fruits (Bokbunja). Anthocyanin fraction extracted from Bokbunja revealed the presence of three anthocyanin components, which were tentatively identified as cyanidin 3-O-sambubioside, cyanidin 3-O-xylosylrutinoside and cyanidin 3-O-rutinoside using RP-HPLC/DAD/MS. The anthocyanin fraction from Bokbunja always showed reducing power and high scavenging activities against DPPH, hydroxy radical (OH) and superoxide anion radical ($O_2{^-}$) similar to general synthetic antioxidant and polyphenol compounds from plant origin. Anthocyanin fraction from Bokbunja showed high inhibition on proliferation of LNCaP and A549 cells and did not inhibit the proliferation of other cancer cells. Immuno-activities of Anthocyanin fraction from Bokbunja were investigated, it showed high promotion of human B and T cells growth about 50% and secretion of IL-6 and TNF-${\alpha}$ by treatment after 6 days. Over all, the result of the study suggest that anthocyanin fraction from Bokbunja displays antioxidant activity comparable to that general synthetic antioxidant, also, anthocyanin fraction from Bokbunja are expected to be good candidate for development into source of anticaner and immuno-activator agent in food industry.

  • The immune activities of Ganoderma lucidum Mycelium added garlic extracts (GAM), Ganoderma lucidum Mycelium (GM), garlic extracts (GS) and standard $({\beta}-glucan)$ were compared. GAM enhanced the growth of human immune T cell up to $1.25{\sim}1.46$ times, compared to control group. GAM showed relatively lower cytotoxicity in using normal human lung cell, while GAM showed the most potent inhibitory effect on the human lung carcinoma, compared to GM and GS. The selectivity of GAM was also higher than that of GM and GS. GAM increased the secretion of cytokines, IL-6 and TNF- from human B cell as well as the growth of human immune cells. It can imply that GAM has higher immune activity than GM or GS.

  • Curcuma longa L. leaf was extracted by water at $60^{\circ}C$ for 12 hours after being treatment of Ultra High Pressure under 500 MPa for 5-15 minute. The high pressure extraction for 15 minute (HPE15) was measured the highest extraction yield of 25.48% (w/w), compared to those from conventional extraction methods. The HPE15 showed the lowest cytotoxicity as 11.97% in adding $1.0mg/m{\ell}$ of concentration. Also, HPE15 was measured the highest inhibition of hyaluronidase as 44.48% in adding $1.0mg/m{\ell}$. In addition, The production of NO from macrophages was measured as $7.06{\mu}M$ in adding $1.0mg/m{\ell}$ of HPE15, which was lower than the those from others processes. Finally, HPE15 significantly reduced up to $649.44pg/m{\ell}$ of $ProstaglandinE_2$ production from UV-irradiation. These results suggest that the Curcuma longa Linne leaf extract from high pressure process might enhance the skin immune activities possibly by high elution of active components than other processes.

  • The prescriptions (DB-1-DB-5) were prepared with the active herbal medicines, Acanthopanax senticosus, Glycyrrhiza uralensis, Polygonatum odoratum, and Cichorium intybus. The most active crude polysaccharide fraction (DB-2-3), which was isolated through the fractionation of hot-water extract from DB-2, was significantly reduced by periodate oxidation (52.7 and 63.7%) on intestinal immune system modulating and anticancer activity. When DB-2-3 was further fractionated by column chromatographies, DB-2-3IIc-2 showed the most potent activities. In addition, DB-2-3IIc stimulated the proliferation of bone marrow cells via Peyer's patch in dose-dependent pattern by oral administration. The metastasis of colon 26-M3.1 lung carcinoma had significantly inhibited in mice fed DB-2-3IIc at 1 mg/mouse (43.8%). DB-2-3IIc-2 mainly contained uronic acid (46.1%) and 42.5% of neutral sugar with a small amount of protein (7.6%), and component sugar analysis also showed that DB-2-3IIc-2 was composed Ara, Gal, and GalA (molar ratio; 0.50:0.63:1.00). It may be suggested that activities of DB-2-3IIc-2 are resulted from pectic polysaccharides containing a polygalacturonan moiety with side chain of neutral sugars, such as Ara and Gal.

  • The scope of the research is investigation of immune-modulating activities of A. rugosa (Baechohyang) extract was preformed through the screening active constituents using in vitro assays and evaluating anti-inflammatory activity and anti-atherosclerotic activity of the extract and active compound (tilianin) in vivo. In addition, various functional foods using the extract and whole plant was developed. The extract showed strong anti-inflammatory activity in carrageenan-induced acute edema mouse model and anti-atherogenic lesion activity in LDLR (low density lipoprotein receptor) deficient mouse model. These activities were thought to be resulted from modulation activity of several pathways of inflammation process. Among the main constituents of Baechohyang, polyunsaturated fatty acids (PUFA), Phytosterols, oleanolic acid and rosmarinic acid showed anticomplement activity, and PUFA, acacetin and tilianin newly showed potent ICAM-1 expression inhibition activity. The processes of extraction, mixing ratio of additives and storage conditions were established for drinks, granule tea, leaf tea, mixed tea and furigake.
