“…The refractive index value is consistent with those found for the conventional oils [31]. Furthermore, the saponification index of P. vitifolia seed oil is lower than the one reported for passion fruit [32,33] or soybean [31]. However, it is similar to that of corn oil [31] (Table 1).…”

Objective: The objective of the study was to establish potential uses of the fruit peel and seeds from Passiflora vitifolia collected in the Colombian Central Andes. Methods: The physical characteristics and chemical profile of the byproducts were determined. The ethanolic extracts of these materials were used to assess the content and phytophenols composition, to establish the antioxidant potential and the antidiabetic activity, in vitro inhibition of α-amylase enzyme and glucose diffusion. The performance and physicochemical composition of the seed oil was also evaluated. Results: The seeds contain almost 4 times more phenolic compounds (10 671 mg GAE/100 g sample) than the peel (2817 mg GAE/100 g sample). Likewise, crude protein and fat contents from the seeds are higher (15.5% and 25.6%) than the peel (6.60% and 5.70%, respectively). Nine phytoconstituents were positive for both extracts. Significant variation (p<0.05) of antioxidant and anti-hyperglycemic potential was observed among the peel and seeds in all methods applied. Conclusion: Results showed that the byproducts of P. vitifolia fruit could be used to enhance the nutritional quality of functional products. These findings were also confirmed by the ethanolic extract from seeds, which revealed high levels of phenolics, high antioxidant potential, and anti-hyperglycemic activity that make it a promising phytotherapeutic product, all of which gives added value to the fruit of this wild Passiflora.

“…Iodine index for the sample analyzed is comparable to Passiflora edulis f. flavicarpa (the most marketed passionflower in Colombia [1]) and corn oil [31][32][33][34]. With the iodine index above 100, the oil can be considered as semi-drying.…”

“…During storage, seed conservation is strongly associated with moisture content which affects speed of metabolic activities and chemical composition of the seed (Marcos-Filho, 1999). Silva et al (2017) reported that in the three phases of fruit maturity, there were minor fluctuations in seed moisture content throughout storage; a little decline was noted up to twelve months of storage. Khan (2019)…”

“…Because seed quality peaks at physiological maturity, knowing when this stage of development occurs can help a seed farmer optimize following activities like harvesting and drying in order to maximize seed germination and vigor. According to Silva et al (2017), seeds reach their peak quality toward the end of the seed filling stage, after which viability and vigour drop. Picking okra seed pods should be done when they are completely dry.…”

Field experiments were conducted to study the effect of harvesting stages i.e. (mature pod of turning stage, brown undried stage and brown dried stage) on seed yield and quality attributes of okra sown at different dates (March 10, March 30, April 19 and May 9) at Agriculture Research Institute Tarnab Peshawar, during 2016 and 2017. A Randomized Complete Block Design (RCBD) with split plot arrangement having sowing dates as the main plot factor, while harvesting stages as sub plot factor was used. The seeds of okra, after harvesting and drying were packed in polythene bags and stored for 0, 3 and 6 months at room temperature. The seed quality attributes were evaluated at the specified storage duration. It is evident from the results that sowing dates, harvesting stages, storage duration and their interaction significantly affected seed yield and quality parameters of okra. The average of two years results showed that maximum pod length (15.23 cm), number of seeds pod -1 (58.09), seed weight pod -1 (3.57 g), 1000 seed weight (g), seed yield (1.72 t ha -1 ), germination (79.61 %) and seed viability (91.85 %) were observed in seeds harvested from plants sown on March 30 as compared to seeds harvested from late sown plants on May 9. Highest hard seed (23.69 %) was recorded in seeds collected from late sown plants on May 9 as compared to other sowing dates. As for as harvesting stages are concerned, maximum seed weight pod -1 (3.57 g), 1000 seed weight (61.33 g), seed yield (1.67 t ha -1 ), germination (81.21 %) and seed viability (91.86 %) was recorded when pods were harvested at brown dried stage. Whereas maximum pod length (15.63cm), highest moisture content (12.57 %) and hard seed (26.85 %) were recorded at mature pod of turning stage. The data on seed quality attributes in relation to storage revealed that the highest seed moisture (13.21 %) and seed viability (91.86 %) was recorded in seeds stored for 0 months, but the mean maximum germination percentage (75.58%) and lowest hard seed (17.46 %) was recorded with seeds stored for 3 months. The seed moisture content, germination percentage and seed viability decreased, while hard seeds increased with increasing seed storage duration. The D x H interaction influenced most of the quality attributes such as seed weight pod -1 , germination, hard seeds, but moisture content and seed viability of the seeds was not significantly affected. The H x S interaction also significantly affected the seed moisture content, germination percentage, hard seed and seed viability. So, it can be concluded that sowing on March 30 with pods harvested at brown dry stage resulted in maximum seed yield and quality and slowed down the deterioration of the seeds during storage.

Jatropha curcus belonging to the Family, Euphorbiaceous commonly known as physic nuts. It is well known herb all over the world. J.curcas oil is not edible and is traditionally used for manufacturing soap and other medicinal applications. It is an alternative fuel for diesel engines. This review is based on focusing on the biodiesel production from the plant Jatropha curcas.Production of Biodiesel from Jatropha curcas seed oil involved three steps include extraction of oil from the seed, acid-catalyzed transesterification, and base-catalyzed transesterification, each of which is well-known and widely-utilized in today's biodiesel industry The produced bio diesel was characterized to obtain its physicochemical parameters such as flash point, pour point, cloud point, viscosity and density. The results obtained from the calculation of the yield of oil extracted revealed 54% of oil could be obtained from the Jatropha seeds used. According to the results, the values obtained from the analysis of the oil especially free fatty acid, density and kinematic viscosity of the oil were found to compare well with the standard (ASTM), which was an indication that the extracted oil was good and suitable for biodiesel production The considered parameters oil content, iodine value, peroxide value, saponification value and acid value. These parameters were done in order to study the oil property of J curcas L which makes the oil most suitable for biodiesel production. In these reveals that biodiesel has become more attractive as an alternative to fossil diesel because of its environmental benefits and the fact that it is made from renewable resource. J. curcas L. is a promising source of biodiesel since its seeds contain high amount of oil and the species has good agronomic traits.
