Health Functional Effect of Raspberry Bamboo Salt

Bamboo is used by Korean as an important medicinal material. It has many different medicinal efficacy from its stub, roots and leaves. Raspberry is most often the source of a dietary supplement sold in many health food stores called ellagic acid, and it is viewed as being responsible for a good portion of the antioxidant activity of this (and other) berries. With a special method to make the raspberry(5%) bamboo salt was researched in this study. Bamboo salt sample showed antioxidant, antimutagenicity and in vitro anticancer effects. The radical scavenging effect of raspberry bamboo salt on DPPH radical was tested. The raspberry bamboo salt samples showed better scavenging activities on DPPH radical than other salt samples at concentrations of 10 and 20%, respectively. These radical scavenging activities were more potent than that of common salt. Antimutagenicity effects were investigated with different kinds of salt samples. The antimutagenicity effects showed a similar trend as shown in the radical scavenging effect. In the MTT assay with human AGS gastric cancer cells, the raspberry bamboo salt (89%) showed better anticancer activities than 9 times baked bamboo salt (47%) and solar salt (22%) at a concentration of 1%, and raspberry bamboo salt also showed better anticancer activities than other salt samples at the low concentration of 0.5% (p<0.05). Apoptosis related genes were analyzed using RT‐PCR in order to check the anticancer effect in the HT‐29 human colon cancer cells, and showed the same anticancer cancer effects as shown in MTT assay. From the experimental results, raspberry bamboo salt showed the best functional effects compared to other salt samples. This research was supported by Korean Rural Development Administration, Korea.
