“…The increased temperature induced the oil biosynthesis in this species, what was evidenced by correlation tests. A similar effect was found in other species [28][29][30], suggesting that temperature can play a significant role in the biosynthesis of seed oil of C. procera.…”

“…The oil content was inversely correlated with latitude (Table 4). Regions with low latitudes have a longer period of exposure to sunlight [37], and plants subjected to higher rates of sunlight have increased lipid synthesis in their seeds [29,33]. However, in our study, the latitude data from the four localities were very similar (Table 1) and thereby the effect of latitude on the oil biosynthesis of C. procera can be neglected.…”

Calotropis procera is a soft-wooded, evergreen, perennial shrub species which grows in a variety of environments including dry habitats such as the Brazilian semi-arid region. This study aimed to evaluate the variation in the oil content and fatty acid composition of C. procera seeds from four climatically different locations in the state of Pernambuco in the northeast of Brazil. The seed oil content of C. procera ranged from 19.7 to 24.0 %. Five main fatty acids were identified, with a predominance of unsaturated linoleic and oleic acids (approximately 70 %).Our results suggesting that environmental conditions influenced the seed oil biosynthesis of C. procera, because the localities with high temperature and low precipitation had increased oil content and total biosynthesis of saturated fatty acids. Multivariate analysis showed high similarity among three localities which share certain physiographic characteristics and climatic conditions such as temperature and precipitation values. The oil profile of C. procera presents interesting features that highlight its potential as a future alternative for the biodiesel market, especially in semi-arid regions.

“…However there was significant decrease in weight till the end of study as compared to control, compatible with Shotton et al report. This decrease in weight may be due to lowering the low density lipoprotein, cholesterol and glucose caused by GLA [8], present in evening primrose oil [9,10]. Woltil et al, also reported the low birth weight infants by EPO and fish oil [11].…”

Influence of oil content on the equilibrium moisture content of evening primrose ( Oenothera SPP.) seeds

Seed moisture content is a well-recognised index of safe storage. However, when in equilibrium with the storage environment it is merely an indicator of the relative humidity of the air, which is the primary regulator of the growth of moulds and insects. The relationship is influenced by the profile of the seed components. During the 1990s, significant increases in the seed oil content of evening primrose were achieved through plant breeding. This paper shows that the equilibrium moisture content of evening primrose seeds declines significantly with increasing oil content. Hence, the moisture isotherm is altered and newer cultivars must be stored at slightly lower seed moisture contents to ensure that seed and oil quality are maintained.
