Ms. Minori Shoji was born in Hiroshima city. Hiroshima is a peace city that is attracted attention as the 44th President of the United States, Barack Obama visited in 2016. Now, she belong to Graduate School of System Engineering, Kindai University in Japan, and then she research plants and other natural products. Until now, she presented a paper about antibacterial activity and deodorizing activity for the seed oil of both Loquat and Bayberry at an academic conference in Japan. In the future, she would love to work in the cosmetics industry.
The climate of Setouchi region in Japan where is warm and has ample rainfall is suitable for fruit cultivation, and many citrus fruits (oranges, lemons etc.) are cultivated. Especially in Akitsu district of Hiroshima prefecture, there is a long tradition of growing loquats.previous reserches reported on components and physiological function loquat seeds. However, there are limited studies on oil extracted from the loquat seed. In this study, we extracted 35.3 g of loquat seed oil from 15.1 kg of Tanaka Biwa (a variety of loquats) which is easy to obtain. Then, we analyzed fatty acid composition of seed oil and examined its utilization. As a result, we found oil components similar to beef tallow and cocoa butter, and the main components were behenic acid lignoceric acid. In the modern society, problems caused by malodor are considered to be one of major issues. Therefore, we examined deodorizing effect of the loquat seed oil on malodor. In consequence, the extracted oil components demonstrated high deodorizing effect on malodor elements including ammonia, trimethylamine, isovaleric acid and nonenal. In adiition, we found high deodorizing effect on allyl methyl sulfide exhibits very high deodorizing activity by considering the mixing ratio of linoleric acid and lignoceric acid. At the present time, pharmacological activity tests of loquat seed oil components are now being examined
Su, Chen-Wei had completed bachelor degree at the age of 22 years from Pharmacy ＆ Science of Chia Nan University. He is major in pharmacy and go on a field trip to a hospital for four months. After he graduated, he continues to study at Taipei Medical University for master degree. He is major in natural product analysis about the insect metabolomics. He will graduate in June in 2017.
Hermetia illucens L. (HI), the species of Stratiomyidae insects, which lives by livestock manure and kitchen waste. The abundance of protein can be used to produce high-value animal protein feed. In addition, there are many advantages, i.e., reproduce rapidly, euryphagous except human food, raise easily and low cost. Based on the above, HI is a good media for resource transformation. In this study, we applied LC-MS technique combined with statistical analysis (PCA, OPLS-DA) to explore the different growth stages of HI. The growth stages of the larvae are five, the freshly hatched larvae were sacrificed and freeze-dried as the blank of zero stage. The rest of larvae were reared and fed on Sesamum indium (SI), and they would enter the next stage by each peeling. We took the second, fourth and fifth stages by each peeling a week for analysis. According to the LC-MS data, we run the database software-Compound discoverer 2.0 to get predicted compounds information like retention time, chemical formula, and area under the curve. After we get these information, we also run statistical software-SIMCAP to analysis the difference among SI and HI, HI with fed SI. In summary, the results from LC-MS technique combined with statistical analysis can be speculated that the use of energy insects Hermetia illucens L. is not only amino acids, but also free fatty acids.
