This study was to investigate the effect of fermentation extracts on the concentration of serotonin and melatonin in the serum of the ICR mice. The ICR mice were divided into water control group, lactobacillus fermentation solution including (Lactobacillus paracasei and Bifidobacterium longum B6) control group, positive control group (milk and doxylamine succinate), negative control group (caffein) and the groups treated with the extracts of Berberis koreana bark (WE: water extracts, FE-L.P: fermentation extracts of Lactobacillus paracasei, FE-B.L: fermentation extracts of Bifidobacterium longum B6). After ten-day feeding treatment, the mean concentration of serotonin for water control, WE, FE-L.P and FEB. L group was 134.72, 183.01, 232.09 and $223.78 ng/m{\ell}$, respectively. The mean concentration for FE-L.P and FE-B.L group were approximately 66% larger than that for water control group. The mean concentration of melatonin for water control, WE, FE-L.P and FE-B.L group was 76.92, 106.66, 157.56 and $141.81pg/m{\ell}$, respectively. The mean concentration of melatonin for FE-L.P and FE-B.L group were also larger than that for water control group. Our results indicated that the fermentation extracts of Berberis koreana bark have relatively greater potential to induce secretion of serotonin and melatonin. Therefore, the fermentation extracts have antidepressant effect.

This study was performed to investigate the enhancement of cosmeceutical activities of Berberis koreana bark by different extraction processes. The extracts are WE (water extract at $100^{\circ}C$, control), USE (ultrasonification for 1 hours at $60^{\circ}C$ with water), HPE (high pressure for 5 minutes at $60^{\circ}C$ with water) and USE + HPE (ultrasonification process for 1 hours after high pressure for 5 minutes at $60^{\circ}C$ with water), respectively. The cytotoxicity of the extracts was in the range of 24.02~26.94% at 1.0 mg/ml concentration. The USE + HPE showed the lowest cytotoxicity. Compared to the WE, total phenolic and flavonoid contents in the USE + HPE increased to 121.5% and 154.2%. The USE + HPE showed the highest activity at 1.0 mg/ml concentration in 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging, inhibition activity of xanthine oxidase and superoxide dismutase (SOD)-like test, respectively. Tyrosinase inhibition of WE, USE, HPE and USE + HPE at 1.0 mg/ml concentration was measured as 17.72, 19.62, 22.83 and 24.16%, respectively. Hyaluronidase inhibition activities of the USE + HPE were higher than 20.8%~29.5% of the WE. Our results suggested that the extracts from ultrasonification process after high pressure extraction has relatively high cosmeceutical activities, and that the bark of Berberis koreana could be considered as a candidate of new functional cosmetic agents.

본 연구에서는 저온고압 추출공정을 이용하여 전통적인 기존 추출공정과 비교함으로써 저온고압 추출공정에 의한 매자나무 수피의 항산화활성과 항암활성의 증진을 확인하고자 연구를 수행 하였다. DPPH radical 소거 활성은 5분 저온고압 처리한 추출물이 93%로 가장 높은 활성을 나타내며 대조군인 ascorbic acid의 95%와 유사한 활성을 나타내었다. 저온고압 추출공정을 통한 매자나무 추출물이 일반 열수 추출물과 비교해 xanthine oxidase 저해활성이 높게 나타났으며 특히 5분 저온고압 처리한 추출물이 56.68%의 높은 저해 활성을 나타냈다. 따라서 저온고압 추출공정을 통해 매자나무 추출물의 항산화 활성의 증진이 이루어졌음을 알수 있다. 항암활성 측정 결과, 매자나무 수피 추출물의 높은 항암활성을 확인하였으며 5분 저온고압 처리한 추출물의 암세포 억제 활성이 가장 높게 나타남에 따라 저온고압 추출공정을 통해 항암활성의 증진이 가능함을 확인하였다. 세포독성 측정 결과 5분 저온고압 추출물이 정상 세포에 대한 독성이 가장 높은데 반해 15분 저온고압 처리한 추출물의 세포독성이 제일 낮은 것으로 미루어 저온고압 추출물의 세포독성이 저온고압 추출시간의 영향을 받는 것으로 사료된다. 따라서 매자나무 수피의 생체적용이 가능한 기능성 소재로서의 이용 가능성을 확인할 수 있으며 저온 고압 추출공정의 최적화를 통한 활성물질의 추출 극대화를 통해 높은 경제적 가치를 부여해 줄 수 있을 것으로 사료된다.

The bark of Berberis koreana Palibin was fermented by Bifidobacterium longum B6 and Lactobacillus paracasei at $37^{\circ}C$ for 72 hour, then extracted by water solvent at $100^{\circ}C$ for 180 min. Total pholyphenol and flavonoid contents were improved by fermentation process, compared to conventional water extraction. The barks of B. koreana Palibin extracts by B. longum B6 (FE-B.L.) and by L. paracasei (FE-L.P.) showed 17% and 16% cytotoxicity on human normal cell lines(HEK293) at 1.0 mg/$m{\ell}$ of the highest concentration, respectively, which was about 3~5% lower than 20% from normal extracts (NE). DPPH radical scavenging activity of the FE-B.L. and FE-L.P. were about 73% and 75.9% higher than 56.8% of NE. The highest inhibitory potency on xathine oxidase and superoxide dismutase (SOD)-like activities were also measured as 31.9% and 61.9% by adding FE-L.P. of 1.0 mg/$m{\ell}$. On tyrosinase inhibition test, the FE-L.P. showed highest activity as 75.9% at 1.0 mg/$m{\ell}$. Generally, FE-L.P. showed higher antioxidant activities as well as higher tyrosinase inhibition activity, possibly due to high contents of total pholyphenol and flavonoid. In general, fermentation of barks of B. koreana Palibin has relatively better biological activities than normal extracts. Specifically, the extracts fermented by L. paracasei showed higher activities than that from B. longum B6.
