This study was performed in an effort to create a functional and stable yogurt product containing slander glasswort extract. The extract was added to milk at concentrations of 0.25, 0.5, and 1.0% (w/v), which was then fermented with lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) at $42^{\circ}C$ for 6 hr. During a period of 15 days of storage, the quality characteristics of the yogurt samples were evaluated in terms of acid production (pH and titratable acidity), levels of lactic acid bacteria, color values, viscosity, and sensory characteristics. There were no significant differences in pH during the storage period; however, the control yogurt presented the highest pH value. The 1.0% slander glasswort yogurt had the highest titratable acidity; but again, there were no significant differences among the yogurts. The 1.0% slander glasswort yogurt also had the highest level of lactic acid bacteria, and both the control and slander glasswort-containing yogurts had increasing levels of lactic acid bacteria over the storage period. The 1.0% slander glasswort yogurt had the lowest L-value and highest a- and b-values. And the slander glasswort yogurts presented lower viscosity values than the control. In sensory evaluations, the 0.25% slander glasswort yogurt scored higher than the other groups for color, flavor, viscosity, sweetness, sourness, and overall palatability. The final sensory results indicated that the 0.25% slander glasswort yogurt was superior.

함초 추출물의 장내 이동 효과를 살펴보기 위하여 함초 추출물을 식수에 첨가하여 장 이동률을 살펴본 결과 대조군에 비해 함초 추출물을 처리한 군에서 활성탄 식이의 장 이동률은 8.5-16.4% 증가되었다. 함초 추출물의 변비해소효과는 함초 추출물을 식수에 녹여 공급한 결과 대조군에 비해 함초 추출물을 3 mg/mL 처리한 군에서의 변량이 식수 섭취량과 관련하여 최대 156% 증가하였다. 또한 함초 요구르트의 변비해소효과는 0.25% 함초 요구르트의 공급으로 변비 유발기간 내 변량이 최대 150% 증가되었으며 처리군에 비해 loperamide를 계속 섭취함에도 불구하고 변비가 해소되었음을 알 수 있었다. 이상의 결과로 볼 때 함초 추출물은 장 이동률을 증가시켜 장운동을 촉진할 수 있으리라 생각되며 또한 변비 해소작용까지 나타내어 장 기능 개선에 효과를 나타내는 물질이라 생각된다.

Two flavonoids, isorhamnetin 3-O-$\beta$-D-glucopyranoside (1) and quercetin 3-O-$\beta$-D-glucopyranoside (2), from slander glasswort (Salicornia herbacea, Korean name hamcho) were isolated. Antioxidative and matrix metalloproteinase-9(MMP-9) inhibitory effects of these compounds were investigated in HT 1080 cell lines. These compounds suppressed the electron spin resonance (ESR) signal intensity on generation of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical in a free-cellular system. Their scavenging effects on generation of intercellular reactive oxygen species (ROS) also exhibited similar trends with DPPH radical in the free cellular system. Also, a control group combined only with Fe(II)-$H_{2}O_2$ resulted in DNA apoptosis by oxidative stress, whereas treatments with these compounds suppressed radical-mediated DNA damage. Intracellular glutathione (GSH) levels were slightly increased in the presence of compound 1 and 2. Moreover, these compounds led to the reduction of the expression levels of MMP-9 without cytotoxic influence. These results suggest that these compounds have a potential as a valuable natural antioxidant and MMP inhibitor related to oxidative stress. Therefore, these compounds not only can be developed as a candidate for a therapeutic potential but also a source for use as ingredients of health foods or functional foods to prevent metastasis involving MMP-9, closely related to ROS.
