  • In this study, we investigated the quality characteristics of yogurt with different amounts(0.5, 1.0, 1.5, 2.0%) of Sansuyu(Corni Fructus) extracts. The yogurt products were evaluated for sensory properties, acid production(pH, titratable acidity) and the number of viable cells during storage up to 21 days at $10^{\circ}C$. The products containing 0.5% and 1.0% Sansuyu extracts showed the highest scores for color, smell, softness, taste, and overall acceptability. For the intensity characteristic scores, color, smell and bitter taste increased as the proportion of Sansuyu extract increased. Softness was lowest, but it was highest in the 0.5% and 1.0% Sansuyu extracts. During storage, titratable acidity increased while pH gradually decreased. pH was lower in the sample with Sansuyu extract than that of the control, and the titratable acidity increased with increasing Sansuyu extract content on day 0. There was significant difference in viable cell counts among the samples. These results indicated that the yogurt added with 0.5~1.0% Sansuyu extract was acceptable.

  • Purpose: This study chose Vaccinium oldhamii as a material to complement the redness of Sansuyu, which is unstable to heat, to Sansuyu pudding. Methods: The level of browning and hunter color of Corni fructus juice supernatant (CFS) and Vaccinium oldhamii extract (VOE) were examined and dependent on heating time and storage period. Results: A value (redness) of VOE was high, browning was moderate during the storage period, and though the storage period was extended, the value stayed stable, meaning overall redness was maintained. With the increase in the amount of added VOD, the color preference of Sansuyu pudding, and D (VOE 10.0%) was marked the highest at 5.80. As for the preference of texture, B (VOE not added) was the highest at 5.35, but C (VOE 5.0%) was marked the highest at 5.10 for overall preference. The DPPH radical scavenging ability of Sansuyu pudding was 15.86-21.39% at a concentration of 1,000 ppm, and the total polyphenol content was 136.76-139.62 mg/100 g. Since the redness of Sansuyu is unstable to heat and then is heated, its degree of browning and b value (degree of yellowness) increases. Conclusion: So if a material with a red color that is stable to heat is added to Sansuyu, the preference of Sansuyu products will improve.

  • Cornus officinalis Siebold & Zucc. is traditionally used as an edible and medicinal plant in many countries in East Asia. Previous studies have shown the pharmacological potential of extracts and components of C. officinalis, but comparative analysis of the composition of the leaf, stem, and fruit extracts has been insufficient to date. In the present study, the content of active antioxidant and anti-inflammatory ingredients was verified in different C. officinalis parts (under-ripe sansuyu, ripe sansuyu, seed, leaf, stem, and dried sansuyu). One active component, morroniside, was high in fruit (under-ripe and ripe sansuyu), while loganin was high in fruit (under-ripe sansuyu) and cornin was high in seeds. Total polyphenol contents were highest in fruit (ripe sansuyu) and flavonoids were highest in leaves. DPPH radical scavenging activity was highest in leaves, followed by seeds and then ripe sansuyu extract. The anti-inflammatory efficacy of leaf extracts of C. officinalis (LCO) was further investigated by measuring their effects on levels of nitric oxide (NO) and the pro-inflammatory cytokines interleukin (IL)-1β and IL-6 in RAW 264.7 macrophages. Non-cytotoxic concentrations of LCO effectively decreased the lipopolysaccharide (LPS)-induced expression of inducible NO synthase, resulting in decreased NO production. LCO also significantly suppressed LPS-induced production and expression of IL-1β and IL-6. Taken together, the present findings suggest that C. officinalis leaves have potential as natural materials for the development of antioxidant and anti-inflammatory agents.

  • Estrogen like activities were evaluated using ethanol and hot water extracts of herbal medicines by using an in vitro detection system. Bokryung (Poria cocos), Sanyak (root of Dioscorea batatas) and Mokdanpi (root skin of Paeonia suffruticosa) represented statistically significant estrogen-like activities (p<0.001), while Omija (fruit of Schizandra chinensis), Taeksa (root of Alisma canaliculatum A. BR.), Jihwang (root of Rhemannia glutinosa), and Sansuyu (fruit of Cornus officinalis) did not. Estrogen-like activities of Bokryung hot water extract (500 ${\mu}g/ml$) and ethanol extract (50 ${\mu}g/ml$) were almost same as that of a C M $17{\beta}$-estradiol. Furthermore, estrogen-like activities of ethanol extracts (500 ${\mu}g/ml$) of Bokryung and Mokdanpi were stronger than that of $10^{-7}$ M $17{\beta}$-estradiol. These results suggest that Bokryung, Sanyak and Mokdanpi show estrogen-like activities. Especially, Sanyak and Mokdanpi represented promotive effect on the proliferation of MC3T3-E1 osteoblastic cells. Bokryung, Sanyak and Mokdanpi also exhibited superior inhibitory effect on the viability of RAW 264.7 cells. In conclusion, these three herbal medicines might be interpreted as candidates for the further study or development of functional foods or medicine to prevent or avoid postmenopausal symptoms of women.
