The Phytochemical Composition of Melia volkensii and Its Potential for Insect Pest Management

Plants, 2020
Due to potential health and environmental risks of synthetic pesticides, coupled with their non-selectivity and pest resistance, there has been increasing demand for safer and biodegradable alternatives for insect pest management.

Tracing the biosynthetic origin of limonoids and their functional groups through stable isotope labeling and inhibition in neem tree (Azadirachta indica) cell suspension

BMC Plant Biology, 2018
Background Neem tree serves as a cornucopia for triterpenoids called limonoids that are of profound interest to humans due to their diverse biological activities.

Limonoids from Citrus reticulata [PDF]

Zeitschrift für Naturforschung C, 2003
The seeds of Citrus reticulata afforded the new limonoid derivative, isolimonexic acid methyl ether, in addition to the the previously isolated limonin, deacetylnomilin, obacunone and ichangin. The structure elucidation was achieved primarily through 1D and 2-D-NMR analyses.

Extraction of Limonoids and Limonoid Glucosides with Supercritical Carbon Dioxide.

NIPPON SHOKUHIN KOGYO GAKKAISHI, 1992
最近,その生理活性が注日されているリモノイドおよびそのグルコサイドのカンキツ種子からのより有効な抽出方法としてSC-CO2抽出法について検討した.その結果,供試試料として脱脂乾燥夏柑種子粉末を用いてSC-CO2抽出したときCO2単独では各リモノイドの抽出率は有機溶媒抽出法に比べ著しく低かった.そこで抽出率の向上を目的として抽出温度,圧力,エントレーナーの併用およびCO2量の条件について実験した.リモノイドの抽出率は抽出圧力とCO2量に大きく依存したが,抽出温度の影響はほとんど受けなかった.各リモノイドの抽出率は抽出圧力を高めるに従い増加し, 300kg/cm2で最大となった.また,エントレーナーとしてはアセトンを添加したとき最も効果的であった ...
