天然苦味料ジャマイカカッシア抽出物製品の主構成成分についてLC/MS,HPLCを用いて検討した.また,主有効成分クアシンを単離・精製し,その構造をMS,NMRにより確認した.さらに,得られたクアシンを標品として絶対検量線法により製品中のクアシンおよびネオクアシンの含有量を検討した結果,それぞれ21.4%および55.5%であることを明らかとした.また同時に,ジャマイカカッシアと同科植物であるニガキよりニガキ抽出物を調製し,ジャマイカカッシア抽出物製品と比較したところ,その成分組成が異なることを明らかとした.

Jamaica quassia extract, a natural bittering agent, is described as “a substance extracted from bark of Jamaica quassia (<i>Quassia excelsa</i> SW.)” in the List of Existing Food Additives in Japan. The constituents in Jamaica quassia extract product were investigated as a part of an ongoing study to evaluate its quality and safety as a food additive. The main constituents of the extract were identified as quassin and two isomers of neoquassin by using LC/MS. The main constituent, quassin, was isolated and the structure was determined by spectral means. The quantification of their main constituents was performed by HPLC using quassin as a standard, and the concentrations of quassin and total of neoquassin isomers were 21.4% and 55.5%. In addition, it was confirmed that Jamaica quassia extract was different from quassia extract, which is extracted from bark of <i>Picrasma quassioides</i> BENN. belonging to the same family as <i>Q. excelsa</i>, by comparing their HPLC profiles.
