Corni Fructus (CF) is a fruit of Cornus officinalis Sieb. et Zucc. and has been used as traditional oriental medicine. It has various functional qualities such as being antioxidative, anti-inflammatory, antidiabetic, antihyperglycemic, and immunity-regulating. In the current study, CF was extracted from two conventional extract solvents (distilled water (DW) and 70% ethanol) with/without high-speed homogenization (HSH) treatments. The extract was characterized by measuring the total polyphenol contents and antioxidant activities. The HSH treatment significantly improved the total polyphenol content (from 28.4±0.9 mg/mL to 35.5±0.9 mg/mL), ABTS (from 59.8±0.4% to 78.4±2.7%), and DPPH radical scavenging activities (from 50.8±1.4% to 59.7±2.8%) of the DW extract and showed a level similar to that of 70% ethanol extract. The CF extracts were further used to prepare functional jelly with gelatin and other components such as pectin, fructooligosaccharide, and citric acid. The jelly’s hardness, springiness, gumminess, and cohesiveness were characterized using a texture profile analysis (TPA).

Yogurt is mostly consumed dairy food and considered as a nutritious food because of its probiotics such as lactic acid bacteria (LAB). LABs are known to possess antioxidant, anticarcinogenic and antimicrobial effects. Corni fructus has healthy and pharmacological effects such as the inhibition of apidogenesis and angiopoiesis. Thus, the purpose of this study was to evaluate quality characteristics and antioxidant activity of yogurt supplemented with water and ethanol extracts of corni fructus. Yogurt was manufactured with addition of 0.1%-0.2% (w/v) water or ethanol corni fructus extracts, respectively. For quality characteristics, pH, chromaticity, viscosity and syneresis were determined during refrigeration storage (1, 7, 14, and 21 day). For antioxidant activities, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activities were examined during storage. The pH showed no significant difference between groups but showed decreasing pattern for all groups during storage period. In chromaticity, redness increased, and lightness decreased as the amount of corni furctus extracts increases. Yogurt with corni furctus ethanol extracts showed more color changes than yogurt with corni furctus water extracts. Viscosity increased in corni furctus extract added groups, compared to control. Syneresis was approximately 2-fold higher in corni fructus extract added groups, while there were no significant changes between control and extract added groups. Both DPPH and ABTS radical scavenging activities were significantly higher than control group in corni fructus extract added groups, compared to control. In conclusion, addition of corni fructus extracts in yogurt improved quality characteristics during storage and antioxidant properties.

The extraction yield of Corni fructus was about 47.5% by extract apparatus. This study was done to investigate the antidiabetic and antioxidative effects of Corni fructus in Streptozotocin (STZ)-induced diabetic rats. The contents of serum glucose, total cholesterol and hepatic lipid peroxide, glutathione were significantly decreaed (p<0.05) in Corni fructus treated group compared to the those of STZ-control group, also content of triglyceride (TG), atherogenic index (AI) and activity of catalase were decreased, but not statistically significant. High density lipoprotein (HDL)-cholesterol and HDL-cholesterol/total cholesterol ratio (HTR) were increased in Corni fructus treated group compared to the those of STZ-control group. The activities of glutathione-S-transferase (GST) and superoxide dismutase (SOD) were significantly decreaed (p<0.05) in Corni fructus treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-phosphate dehydrogenase (G-6 PDH), glucokin-ase were significantly increased, but activity of glucose-Grphosphatase (G-6 Pase)was decreased in Corni fructus treated group compared to the those of STZ-control group. Therefore, these results indicated that ethanol extract of Corni fructus would have antidiabetic and antioxidative effects in STZ-induced diabetic rats.

This study investigated the effects of pressurized steam-treated Corni Frutus (PSC) extract on osteoblast differentiation and osteoclast formation. The osteoblast differentiation effect of the extract was evaluated by measuring cellular alkaline phosphatase (ALP) activity, cell matrix ALP staining, alizarin Red S staining and von Kossa staining on proliferating MC3T3-E1 osteoblast cells. The results confirmed that ALP activity, cell matrix ALP staining, alizarin Red S staining and von Kossa staining were all increased as proliferation increased from 1 to 14 days, without cytotoxicity. The osteoclast formation effect of the PSC extract was evaluated by measuring the cellular tartrate-resistant acid phosphatase (TRAP) activity and cell matrix TRAP staining on receptor activator of nuclear factor kappa-B ligand (RANKL)-induced RAW264.7 osteoclast cells. Treating RAW264.7 cells with RANKL for 7 days increased matrix staining for TRAP and cellular TRAP activity. The PSC extract decreased these changes in a concentration-dependent manner. Therefore, PSC is expected to be a natural source for developing health functional foods and medicinal agents to prevent bone-related diseases, such as osteoporosis, by increasing osteoblast differentiation and reducing osteoclast activity.

The aim of this study was to investigate functional food material for the antioxidant and biological activities of untreated and steam-treated Corni fructus extracts in extraction solvents (through hot-water extraction, 50% ethanol extraction, and 50% methanol extraction). The yield of UCH (hot-water extract of untreated Corni fructus) was 47.45% and it was higher than those of extracts (13.20-27.18%) obtained by the other extraction methods. The total phenolic and flavonoid contents were 12.23 g/100 g (SCE, 50% ethanol extract of steam-treated Corni fructus) and 5.08 g/100 g (SCE), respectively, and the total sugar content was 71.32 g/100 g (SCH, hot-water extract of steam-treated Corni fructus). The main organic acid components of the extracts were oxalic acid, citric acid, malic acid, formic acid, and gallic acid. The DPPH and ABTS radical scavenging activities of SCE at 1,000 μg/mL were 72.37% and 43.15%, respectively. The ferric-reducing antioxidant power of SCE at 1,000 μg/mL was 689.49 μM. The extracts were investigated for their function in L-132, RAW 264.7, HeLa, and MCF-7 cell lines. The SCE performed better than the other extracts in terms of its protective effects against oxidative stress in L-132 cells and increased the production of NO. Further the SCE showed antitumor activities against HeLa and MCF-7 cancer cells. Therefore, the SCE extracts is a good functional food material for the prevention of woman disease. Therefore, in our study, the SCE extracts is good functional food material for the prevention of oxidant, immunological, and tumor related disease.

The antioxidant and anti-inflammatory effects of Corni fructus extracts (CEF, EtOAc extraction; CBF, buthanol extraction; CWF, water extraction) were investigated. The total phenolics of CEF (173.3 mg TAE/g) were significantly higher than those of CWF (26.7 mg TAE/g) and CBF (94.8 mg TAE/g). DPPH and ABTS free radical scavenging activity of CEF (DPPH: RH50; 25.1 μg/mL, ABTS: RC50; 36.1 μg/mL) showed even higher than that of BHA and α-tocopherol used as positive control. All three Corni fructus extracts in the concentration of 1~100 μg/mL were effective inhibitors of NO and prostaglandin E2 (PGE2). NO production was inhibited 71.3~92.2% by CEF, 76.8~85.5% by CBF and 74.4~96.9% by CWF, respectively. CEF, CBF and CWF (1~100 μg/mL) inhibited also pro-inflammatory cytokines like TNF-α, IL-1β and IL-6 very effectively. TNF-α was inhibited up to 51.2% by CWF and IL-1β was inhibited up to 67.1% by CEF. IL-6 was best inhibited by CEF up to 58.9%. This study suggested the potential of Corni fructus for use as an excellent antioxidant substance and inflammatory inhibiting mediators. Therefore CEF, CBF and CWF Corni fructus extracts may be used for therapeutic approach to various inflammatory diseases.
