The aim of this study was to show the antioxidant properties of chestnut (Castanea crenata) bur extracts fermented by Lactobacillus casei. The chestnut has been used as a cosmetic material in Korea for many years. This study showed that reactive oxygen species (ROS) were inhibited by the fermentation materials of chestnut bur extracts. The antioxidant activities were analyzed and expressed as EDA, ABTS, reducing power, SOD-like activity, hydrogen peroxide scavenging activity, superoxide anion radical scavenging activity, and nitric oxide scavenging ability. The antioxidant activities of fermentation materials from L. casei of chestnut bur extracts were higher than those of butylated hydroxyanisole (BHA), epigallocatechin gallate (EGCG), and ascorbic acid (AA). Therefore, we expect that fermentation materials from L. casei of chestnut bur extracts are valuable resources as natural antioxidants and functional cosmetics ingredients.

This study was performed to elucidate the antioxidative and antiaging activities of mixed rates 2:6:2(262), 6:2:2(622) and 4:4:2(442) of fermented soybean, fermented rice bran, fermented red ginseng based on the comparision with their separate results of our three previous studies. The antioxidative and antiaging effects of 262, 622 and 442 mixed ratios were evaluated by the determination of superoxide radical scavenging activities, hydroxy radical scavenging activities, linoleic acid inhibition activtiy, elastin synthesis activity, and cell viability of B16F10. The material of 442 ratio showed the higher effects than those of 262 and 622 ratios, and presented the higher effect than the separate material of red ginseng in the antioxidative and antiaging activities. Therefore, this study suggested that the material of 442 ratio in the production of red gineng-containing cosmetics could be preferred as a useful cosmetic ingredient for antioxidation and antiaging.

The water fern Azolla belongs to the Azollaceae and forms a symbiotic association with a $N_2$-fixing cyanobacterium, referred to as Anabaena azollae, and this association has currently been demonstrated to have potential as a nitrogen source for rice production. Because of that, Azolla fern has been used not only as organic manure in southern China and northern Vietnam for a long time but also as food for animate creatures in the underwater and decontaminant in the water. However, the phenolic compounds and active materials of Azolla have not been examined in detail in the past studies. In the present study, anti-oxidant ability test and experiment to find a particular active material of Azolla imbricata and Azolla imbricata fraction (AIF) were performed. In anti-oxidant test such as DPPH test and lipoxygenase inhibition test, the value of test represented high activities compared with authentic sample - green tea and NDGA (nordihydroguaiaretic acid). In MMP-1 test, related to collagen protection and elasticity of skin, its inhibitory effect was measured over 75 %, and the phenolic compounds of AIF related with this activity were confirmed luteolin derivatives by using FT-IR spectroscopy, element analyzer (EA) and Liquid chromatography-MASS spectroscopy.
