Analysis of Chaulmoogra Oils. I. Carpotroche brasiliensis (Sapucainha) Oil

Abstract: Vol. 60 acids were distilled helped to make the separation possible. Repeated fractionation of the fractions with high iodine number and high rotation finally gave an ethyl ester which had a constant boiling point (214°a t 10 mm.) and the theoretical iodine number. The specific optical rotation of this fraction was +55.4°. This same rotation was obtained from several fractions made by the above method. Boiling points were recorded by a calibrated millivoltmeter attached to a thermocouple at the top of the colu… Show more

“…Estes autores destacaram ainda a presença de diácidos na mistura do óleo envelhecido. 15,17 Baseado nestes resultados, o óleo de sapucainha foi deixado sobre a bancada do laboratório em um frasco incolor, tampado e a temperatura ambiente por um período de 3 anos. Esta amostra foi analisada por CG-EM e CG-DIC após esterificação com diazometano e confrontada com as análises da amostra guardada ao abrigo da luz (frasco âmbar tampado) e sob refrigeração.…”

“…It is commonly known as sapucainha and has several other local popular names such as canudeiro, babado fruit, comona fruit, cotia fruit, leprosy fruit, monkey fruit, mata-piolho, papo de anjo, pau de anjo, pau de cachimbo, pau de cotia, pau de lepra, and ruchuchu (1). The oil extracted from the seeds, whose major fatty acids are hydnocarpic, chaulmoogric and gorlic acids (2,3), has parasiticidal and anti-leprotic properties ( Figure 1) (1,2,4,5). This class of cyclopentenyl fatty acids seems to be restricted to the seed oils of two tribes of the Flacourtiaceae family, Oncobeae and Pangieae (3).…”
