Oil from pumpkin seeds
Pumpkin (Cucurbita pepo L.) is an annual climber and is in flower from July to September, and the seeds ripen from August to October . Pumpkin seeds oil is an extraordinarily rich source of diverse bioactive compounds having functional properties used as edible oil or as a potential nutraceutical. In recent years, several studies have highlighted the medical properties of pumpkin seed oil which is known as strongly dichromatic viscous oil . Researchers have so far focused particularly on the composition and content of fatty acids, tocopherols and sterols in pumpkin seed oil because of their positive health effects [3–5]. Moreover, pumpkin has gained attention as an exceptional protective against many diseases, e. g. hypertension and carcinogenic diseases [6, 7]; due to its health benefits such as antidiabetic , antibacterial , antioxidant and anti-inflammation . The determination of the biochemical and oxidative stability properties of raw material pumpkin seeds oil would contribute to the valorization of such oil especially in pharmaceutical, cosmetic, and food industries.
Although much progress has been reached in the domain of modern medicine, we still notice the lack of efficient wounds healing treatments. The demand for natural remedies is rising in developing countries  as natural substances may be effective, safe and cheap . Basic research has improved our understanding of enhancement and inhibition of wound healing and has given the basis for introduction of novel treatment methods .
In this respect, the proprieties of Cucurbita pepo L. extracted oil have captured our interest. Despite all the proprieties of the pumpkin oil, and to the best of our knowledge, there is no investigation of this oil in wound healing potential. To this end, the current study aims to identify some physico-chemical aspects of the bioactive components of snow white pumpkin seeds oil as well as to highlight its hemostatic and healing potential effects on wound.
Atherogenic rats supplemented with pumpkin seeds showed a significant decrease (p<0.001) in their serum concentrations of total cholesterol and LDL — C as they dropped from 4.89 mmol / L to 2.55 mmol /L and from 3.33 mmol / L to 0.70 mmol / L respectively. Serum concentrations of HDL-C were also significantly elevated in the same group. Although, atherogenic rats supplemented with 2% arginine showed significant increase in serum concentration of HDL-C, no significant changes were observed in their serum concentrations of total cholesterol and LDL-C. Our results showed that treatment of atherogenic rats with pumpkin seeds significantly decreased serum concentrations of TC and LDL-C. Our findings suggest that pumpkin seeds supplementation has a protective effect against atherogenic rats and this protective effect was not attributed to the high arginine concentrations in shine skin pumpkin seeds.
The pumpkin seeds (Cucurbita sp.) from Cucurbitaceae family are usually considered as industrial waste products and thrown out. In some area's seeds are utilized as uncooked, cooked or roasted, although simply for the domestic purpose. As they are rich in protein, fibers, minerals like iron, zinc, calcium, magnesium, manganese, copper and sodium, PUFA (polyunsaturated fatty acids), phytosterol and vitamins, they might be considered important for the food industries. As the seeds are considered as byproduct of the pumpkin fruit, they are cheaper in cost and their utilization is different food products may lead to enhance their nutritional value at lower cost. Health promoting impacts of lady nail pumpkin seeds on the level of blood glucose, cholesterol, immunity, liver functioning, gallbladder, disabilities of leaning, prostate gland, depression, inflammation, cancer management and inhibition of parasites are established. The modification of these agro-industrial waste products into valuable elements is probably a huge footstep towards the direction of the universal efforts in food sustainability; hence, the further researches and studies should be planned to explore importance and beneficial effects of pumpkins and their seeds.
The observed benefits can attributed to the presence of bioactive components like phytosterols (eg, beta-sitosterol, stigmasterol), tocopherols, selenium (antioxidant), cucurbitin, squalene, lignan, and cardioprotective unsaturated fatty acids. Recent research has shone a light on the ever growing list of benefits of inshell snow white pumpkin seeds 9cm as a valuable food.
