The lipophilic and phenolic extractives of the ripe mesocarp of four cherimoya cultivars ('Perry Vidal', 'Mateus I', 'Mateus III' and 'Funchal') from Madeira Island, were studied for the first time. The predominant lipophilic compounds are kaurene diterpenes (42.2-59.6%), fatty acids (18.0-35.6%) and sterols (9.6-23.7%). Kaur-16-en-19-oic acid is the major lipophilic component of all cultivars accounting between 554 and 1350mgkg(-1) of dry material. The studied fruits also contain a high variety of flavan-3-ols, including galloylated and non-galloylated compounds. Five phenolic compounds were identified for the first time: catechin, (epi)catechin-(epi)gallocatechin, (epi)gallocatechin, (epi)afzelechin-(epi)catechin and procyanidin tetramer. 'Mateus I' and 'Mateus III' cultivars present the highest content of phenolic compounds (6299 and 9603mgkg(-1) of dry weight, respectively). These results support the use of this fruit as a rich source of health-promoting components, with the capacity to prevent or delay the progress of oxidative-stress related disorders.
The ripe pulp of Mangifera indica L.: a rich source of phytosterols and other lipophilic phytochemicals

The chemical composition of the lipophilic extracts of the ripe pulp of mangoes from twelve cultivars of Mangifera
indica L. from Madeira Island was investigated by gas chromatography–mass spectrometry (GC–MS) for the first
time. The ripe pulp of these mango cultivars showed analogous amounts of lipophilic extractives, as well as sim ilar qualitative chemical compositions. The predominant compounds were free and glycosylated sterols and fatty
acids, representing 44.8–70.7% and 22.6–41.9%, respectively, of the total amount of lipophilic components. Small er amounts of long chain aliphatic alcohols and α-tocopherol were also identified. These data indicate that the
investigated mango cultivars are a rich source of valuable phytochemicals, contributing to the intake of at least
9.5–38.2 mg of phytosterols (free and glycosylated) and 0.7–3.9 mg of fatty acids (ω−3 and ω−6) per 100 g
of fresh mango, with recognizable beneficial effects on human nutrition and health.
