Способ включает экстракцию при комнатной температуре и очистку методом твердофазной экстракции (ТФЭ). Для экстракции масла из семян можно воспользоваться н-гексаном. В таком случае экстракт может быть непосредственно очищен сорбцией на насадочных картриджах, заполненных силикагелем. Однако перед очисткой необходимо убедиться в отсутствии каталитической активности сорбента по отношению к лабильным сопряженным триеновым соединениям. Установлено, что при сорбции на силикагеле некоторых коммерческих марок вещества, содержащиеся в масле, могут быстро разрушиться. При использовании предложенного способа масличность семян была оценена на уровне 53 %, и после очистки было получено прозрачное масло с коэффициентом преломления 1,503, типичным для масел с высоким содержанием ненасыщенных соединений. Методом обращенно-фазовой ВЭЖХ установлено, что масло имеет тот же набор триацилглицеринов (ТАГ), что и масло момордики другого вида — момордики харанция (M. charantia), и содержит ди-α-элеостеарат-стеарат в качестве основного компонента (47,9 ± 0,5 моль %). Каждый из триацилглицеринов имеет изомер, в котором радикал β-элеостеариновой кислоты заменяет один радикал α-элеостеариновой кислоты. Жирнокислотный состав масла, рассчитанный по составу ТАГ, следующий: 62,1 ± 0,3 % суммы элеостеариновых, 11,2 ± 0,3 % линолевой, 5,5 ± 0,2 % олеиновой, 1,5 ± 0,2 % пальмитиновой и 19,7 ± 0,4 % стеариновой кислот.</p></abstract><trans-abstract xml:lang="en"><p>A method of gac (Momordica cochinchinensis) seed oil sample preparation is proposed with allowance for high chemical lability of the compounds containing conjugated C=C-bonds. The method includes extraction at room temperature and purification by solid-phase extraction (SPE), n-hexane being a convenient solvent for oil extraction from seeds and the extract can be directly purified by oil sorption on the syringe (packed)cartridges filled with silica gel. However, before cleaning, it is necessary to verify the absence of catalytic activity of the sorbent towards chemically labile conjugated trienoic compounds. It has been shown that some commercial grades of silica gel can quickly disintegrate the oil. Using the developed method we obtained transparent seed oil with a refractive index of 1.503 typical for highly unsaturated oils, the oil content of seeds being 53%. Data of reversed-phase HPLC revealed the same set of triacylglycerols (TAG) characteristic of another Momordica species bitter melon (M. charantia) and contains di-α-eleostearate-stearate as a main component (47.9 ± 0.5 mol. %), each of triacylglycerol set has isomers wherein the radical of α-eleostearic acid is replaced by radical of α-eleoctearic acid. Fatty acid composition of the oil, calculated from TAG composition contains: 62.1 ± 0.3% eleostearic acids, 11.2 ± 0.3% linoleic, 5.5 ± 0.2% oleic, 1.5 ± 0.2% palmitic and 19.7 ± 0.4% stearic acids.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пробоподготовка</kwd><kwd>твердофазная экстракция</kwd><kwd>растительные масла</kwd><kwd>Momordica cochinchinensis</kwd><kwd>кислоты с сопряженными двойными связями</kwd><kwd>ВЭЖХ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sample preparation</kwd><kwd>solid phase extraction</kwd><kwd>vegetable oil</kwd><kwd>Momordica cochinchinensis</kwd><kwd>acids with conjugated double bonds</kwd><kwd>HPLC</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Khanal R.
