The oil content of several members of Bombacoideae were evaluated for their fatty acid composition, including Adansonia digitata, A. fony, A. za, A. madagascariensis, A. suarezensis, A. grandidiera, Bombax costatum, Chorisia speciosa, Lagunaria patersonii, Pachira glabra, P. aquatica, and Ochroma lagopus. Among normal fatty acids, palmitic acid (147), stearic acid (152), oleic acid (154), linoleic acid (155), linolenic acid (156), and sterculic acid (164) were observed in most species. Caproic (143), caprylic (144), arachidic (157), lignoceric (160), and vernolic (161) acids were found in B. costatum seed oil. Investigation of different Adansonia species demonstrated the existence of myristic (tetradecanoic acid) (145), pentadecanoic acid (146), palmitoleic acid (148), heptadecanoic acid (149), heptadecenoic acid (150), heptadecadienoic acid (151), octadec-7-enoic acid (153), arachidic acid (157), eicosenoic acid (158), and behenic acid (159) (Table 15.15).

Chemistry of Syzygium cumini
Published in K. N. Nair, The Genus Syzygium, 2017
Saturated, unsaturated, epoxy, and cyclopropenoid fatty acids have been detected in seed oil of S. cumini. The usual fatty acids from seed oil of S. cumini include lauric acid (118), myristic acid (119), palmitic acid (120), stearic acid (121), oleic acid (122), and linoleic acid (123), along with cyclopropenoid fatty acid malvalic acid (124), sterculic acid (125), and an epoxy fatty acid, vernolic acid (126), having abundances of 2.8%, 31.7%, 4.7%, 6.5%, 32.2%, 16.1%, 1.2%, 1.8%, and 3.0%, respectively, in seed oil (Saeed et al. 1987; Daulatabad et al. 1988). Conversely, more recent GC analysis of seed extract revealed that the percentage of 122 is the highest, followed by 123 (Kumar et al. 2007). In the seed extract, 4-(2-2-dimethyl-6-6-methylenecyclohexyl)butanol (127), decahydro-8a-ethyl-1,1,4a,6-tetramethylnapthalene (128), octadecane (129), 1-chlorooctadecane (130), and tetratetracontane (131) were identified by gas chromatography (Kumar et al. 2009), and the presence of eleostearic acid (132) was detected by spectroscopic methods from seed oil (Das and Banerjee 1995).

Sterculic acid (SA) is a cyclopropenoic fatty acid that occurs naturally in seed’s triglycerides of plants from the order Malvales (25). SA is a natural inhibitor of SCD activity In Vivo and In Vitro, so it has been proposed as a tool for the treatment of some pathologies, such as metabolic syndrome, nonalcoholic steatohepatitis, Alzheimer’s disease, cancer, and retinal disorders (13,26–32). In our group, we have obtained sterculic oil from the seeds of Sterculia apetala and Sterculia mexicana trees located in the tropical rainforests of southeastern Mexico. People in this area use to dry, boil or roast the seeds to develop a nutlike or peanut butter-like aroma and taste, and uses them for human nutrition and as animal forage. In some areas, grounded seeds are used for chocolate flavoring (33,34). The content of sterculic acid in the sterculic oil we have obtained varies from 30-64% and is usually accompanied with malvalic acid (1-2%) another cyclopropene acid with the ability to inhibit SCD (32). By administering sterculic oil to spontaneously hypertensive rats (SHRs) we have reported reductions in body weight and adiposity, and the improvement of blood pressure (BP), adiponectin, and TG levels (26); in addition, we have demonstrated that sterculic oil administration exerts a protective effect from metabolic syndrome development in a fructose induced rat model (27).
