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
Nai-Wen Mei has completed his PhD from National Tsing Hua University. He is the bioscience division director of Gincare International Enterprises Co., Ltd. He has dedicated himself in this company for 9 years to investigate the bioactivities of ginseng in cooperation with various .institutes and universities.
Ginseng has been proved to be a precious herbal medicine due to its multiple bioactive compounds such as ginsenosides, polyphenols and flavonoids to promote health. With a lack of effective medicinal treatment for poor sperm quality, this study aims to investigate the effectiveness of ginseng supplement on improving sperm quality. Rats were orally gavaged with ginseng powder (100 mg/kg/day) provided by Gincare International Enterprises Co., Ltd for 49 days before sacrifice. The serum total testosterone was measured and the sperm collected from epididymis was quantified and its activity determined. The sperm was also subjected to YE stain for morphology observation. DNA content of testicular cells was differentiated into haploid, diploid (D), tetraploid (T), and S-phase. In addition, haploid cells were further divided into round spermatids (RS), and elongating spermatids (ES). The results indicated that the experimental groups demonstrated a significantly higher ratio of sperms with normal type morphology than the control groups (62.4 ± 3.5% to 54.7 ± 2.8%). Amongst the different types of morphological abnormalities, the ratio of sperms with abnormal tail (28.0 ± 3.8% to 34.2 ± 3.6%) and multiple abnormalities (1.8 ± 0.5% to 3.2 ± 1.3%) was especially reduced. The DNA content in testicular cells on the other hand, showed higher percentage of diploid type, which indicated spermatogonium, primary spermatocytes, and meiotic prophase of spermatocytes as the preferable cell types after ginseng supplement. In conclusion, our study suggests a potential advance in ginseng supplement to produce more normal sperms for reproduction purpose.
