Physiological activity and antioxidative activity of Maesangi(Capsosiphon fulvescens) extracts with distilled water or 95% ethanol were investigated. For the evaluation of physiological and antioxidative activities, some evaluation assay methods such as measurement of Hunter color value, chlorophyll a/b value, total phenolics, reducing power and thiobarbituric acid(TBA) value of soybean oil were used. Proximate composition and mineral contents of Masaengi were orders of crude protein>crude fiber>moisture>crude ash>crude lipid, and K>Ca>Mg>Na>P>Fe>Zn, respectively. In ethanol extract, the content of total phenolic compounds in Maesangi was determined to half times of that in Dasima(Laminaria). The reducing power of Maesangi-ehtanol extract was about 5 % of vitamin C and was lower than that of Dasima-ethanol extract. The TBA value of Maesangi-ethanol extract on soybean oil oxidation was about 47 % and 68.4 % to control in three and eight days oxidation, respectively. But TBA value difference was not observed significantly with the dosage below 5mL of ethanol extract.

To evaluate the effect of Hydrangea serrata Seringe extract on kakdoogi(Korean radish kimchi), the kakdoogi was prepared, after supplementation, with Hydrangea serrata Seringe extract(0, 1.25, 2.5 and 5%(v/w)). The quality characteristics of the kakdoogi were investigated during 7 days of fermentation at $20^{\circ}C$. The proximate components of the Hydrangea serrata Seringe leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values in the samples with the extract were higher than that of both the control group and the sugar group. The total acidity levels in the sugar group was higher than that of other groups. The sugar group showed higher L value(lightness) than that of kakdoogi fermented with the extract. A value(redness) and B value(yellowness) of the supplemented kakdoogi was lower than that of the control and the sugar group on day 7. The hardness of samples with the extract was higher than that of the sugar group. And the hardness of the groups with the extract was not reduced during the fermentation period. The control group showed higher salinity than the other groups by day 4. The samples with the extract were sweeter than the control group on day 0 then the difference disappeared after day 2. Sourness of all the groups increased during the fermentation period. However the extract did not affect the hardness or overall acceptability of the kakdoogi during fermentation.

Madhuca indica has been used ethnomedically in Indian folks. In the present study we have investigated anti-inflammatory, anti-ulcer and hypoglycaemic effect of ethanolic extract (EE) and crude alkaloid extract of Madhuca indica seed cake on albino rats. The study showed that the EE had a significant, dose dependent anti-edematogenic, anti-ulcerogenic and hypoglycaemic activity, whereas the crude alkaloid extract exhibited a significant only. Both the extracts possess dose dependent inhibitory activity on carrageenan-induced edema, inhibiting prostaglandins or mediators involved in prostaglandin synthesis, the second phase of inflammation. The EE was significantly effective in protecting pylorus-ligation-induced gastric ulcers at a higher dose level. The active principle of EE seems to be a selective inhibitor of the COX II (prostaglandin synthesis) without important effect on COX I since, EE exhibited both anti-edematogenic and anti-ulcerogenic effect. The EE was effective in reducing the plasma glucose level in normal albino rats in a dose dependent manner, producing hypoglycaemic effect by stimulating the release of insulin from the ${\beta}-cells$ and/or increasing the uptake of glucose from the plasma.
