Cucurbita pepo L. (Pumpkin) is a plant native to Mexico and the USA belonging to the Cucurbitaceae family. It has been domesticated in the New World for thousands of years. This familyincludes cucumbers, melons, watermelon, loofahs, pumpkins, squashes, and gourds. Several species of Cucurbitaceae have been widely used in traditional medicine in Central and North America as a diuretic and as a de-worming treatment. In Ayurvedic medicine, Cucurbita pepo seeds are considered as a diuretic, a cure for bronchitis, fever and effective against parasitic worms.1,2
The pumpkin seeds, known as an important nutritional source are oval, flattened, smooth and light to dark beige color. The seeds are usually cooked, toasted or ground for types different of consumption, as an appetizer, eaten whole. Also, they are ingredient of salads, sauces, cakes, breads additives. Pumpkin seeds have a high protein content and are an important source of minerals such as iron and potassium.3

Punkin Seeds Chemical Composition
Pumpkin seeds contain large quantities of naturally occurring proteins around 35% and unsaturated fatty acids (mainly linoleic acid and oleic acid), tocopherols, and phytosterols. Pumpkin seeds are a source of zinc, phytochemicals as stigmasterol, β-sitosterol, the anthelmintic cucurbitin, squalene, tocopherols, cardio-protective fatty acids which can prevent chronic diseases.4
Flaxseed is known as the richest dietary source of lignans; however, pumpkin seeds contain secoisolariciresinol, a phytoestrogens of the lignan type. Phytoestrogens of the lignan type are widely distributed in plant-derived food and they have potential health benefits.5
Other compound found in sarcocarp and pumpkin seeds is Cucurmosin. This phytochemical is considered toxic to cancer cells and protects against viral, fungal, and bacterial agents. Curcumosin has been shown to induce apoptosis in pancreatic cancer and myeloid leukemia cells.6-8
Nutritional composition and nutraceutical properties of Pumpkin Seed Protein Powder 45%.
Pumpkin Seed Protein Powder 45% is an ingredient rich in protein, obtained from pumpkin seeds. Pumpkin Seed Protein Powder 45% is considered a Super Food due to its balanced nutrient content with pumpkin protein 45% (amino acids including tryptophan), sterols plant, fiber, vitamins K, C, B3, B6, beta carotene, pantothenic acid folate, and minerals as iron, magnesium, zinc, calcium, potassium, phosphorus, calcium. Moreover, pumpkin seed powder is low in fats and carbohydrates. The nutraceutical properties of pumpkin seeds have been investigated in recent years finding many health benefits.
Effects on the Central Nervous System (CNS).
Pumpkin Seed Protein Powder 45% is a source of amino acids including tryptophan. Tryptophan is an amino acid used by the body to synthesize serotonin and melatonin neurotransmitters necessary for regulating sleep cycles and moods. Tryptophan amino acid helps easing insomnia, anxiety disorder, and also for mood enhancement, among others beneficial effects to health. It has been suggested that eating pumpkin seeds along with carbohydrates can help achieve a restful sleep.9-12
Antioxidant properties of pumpkin seed (Cucurbita pepo) protein.
An in vivo study investigating pumpkin seed (Cucurbita pepo) protein isolate antioxidant properties was carried out in a carbon tetrachloride-induced acute liver injury in low-protein fed Sprague-Dawley rat model. The study shown the potential components of the pumpkin seed protein isolate with antiperoxidative properties and their effectiveness in alleviating the detrimental effects associated with protein malnutrition and CCl4 intoxication.13 Another study also showed the antioxidative properties of pumpkin seed (Cucurbita pepo) protein isolate and its capacity alleviating the detrimental effects associated with protein malnutrition.14
Anthelmintic activity.
Traditionally, pumpkin seeds have been used to immobilize and to aid the expulsion of intestinal worms and parasites. Also, some cultures eat pumpkin seeds to prevent worm infections. The anthelmintic effectiveness of dried seeds and extracts has been demonstrated in several in vitro and in vivo studies.15-18 Studies carried out from Chinese traditional medicine have showed the antichistosomal effect of cucurbitin, an amino acid isolated from pumpkin seeds, against S. japonicum.19
Effect on bladder-stone disease
The effect of pumpkin-seed supplementation on oxalcrystalluria and urinary compositions was studied on children in hyperendemic area. Pumpkin seeds lowered calcium-oxalate crystal occurrence and calcium level but increased phosphorus, pyrophosphate, glycosaminoglycans, and potassium values in urine. This clinical trial showed that pumpkin seeds can be used as a potential agent in lowering the risk of bladder-stone disease.20
Protective effect on Benign prostatic hyperplasia (BPH)
Recent studies have shown that pumpkin seed can be useful for the treatment of benign prostate hyperplasia, because of its high β-sitosterol content. Also, β-Sitosterol has been indicated to reduce blood cholesterol and to decrease risks of certain types of cancers.4 Furthermore, other studies have reported that pumpkin seed may have antiandrogenic and anti-inflammatory activity to help easing benign prostatic hyperplasia (BPH). Clinical trials showed that pumpkin seeds preparations improved symptoms associated with BPH such as urinary frequency, urinary flow, residual urine, and micturition time versus placebo.21-24
Cardiovascular effects
An in vivo study with the objective to examine the effect of pumpkin (Cucurbita pepo L.) seeds supplementation on atherogenic diet-induced atherosclerosis showed that treatment of atherogenic rats with pumpkin seeds significantly decreased serum concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C).25
Antidiabetic effects
The hypoglycemic and antioxidant effects of flax and pumpkin seeds mixture was investigated on the kidney of diabetic rats. Diet supplemented with this mixture of seeds ameliorated the antioxidant enzymes activities in diabetic rats, suggesting that flax and pumpkin seeds mixture supplemented in diet of diabetic rats may be helpful to prevent diabetes and its complications.26
Food applications
Pumpkin Seed Protein Powder 45 % is a Super Food with wide potential for the elaboration of protein bars, baking, desserts, baked, fortified breads, cakes, cookies, brownies, muffins, pancakes, protein crepes, protein waffles, plant protein burgers, high-protein pastas, snacks, etc. It can also be consumed in smoothies, shakes, beverages, juices, breakfast cereals and when required to fortify foodstuff with proteins of the highest quality nutritional value.
The interest for protein pumpkin seeds has led to current research on its health benefits. A study was carried out to evaluate the addition of pumpkin protein concentrate and pumpkin protein isolate into wheat flour to produce blends with several protein levels. Results indicated that pumpkin seed products and protein isolate can be added to wheat flour in certain proportion without a detrimental effect on dough or loaf quality for bread fortification. Moreover, the addition of pumpkin seed proteins resulted in increasing protein, amino acids and mineral contents compared to the control.27
The functional properties, antioxidant activity, and dietary fiber content of pumpkin seeds and rind was studied in bread formulations substituted with several contents of pumpkin seed and rind. Results showing high content of fiber, scavenging activity, and overall acceptability and sensory characteristics allow the application of pumpkin seeds and rind as healthy bakery product ingredients.28
Other study carried out to evaluated the effect of incorporation of fiber rich pumpkin powder and guar gum on the farinographic characteristics of wheat flour, concluded that pumpkin seedpowder that can be utilized with guar gum forfortifying breads and baked.29
Food allergy to pumpkin seed and toxicity
Some cases of Cucurbitaceae family allergy has been reported. Oral allergy syndrome pruritus, diarrhea and nausea have occurred in a number of patients. Also, cross-reactivity to watermelon, cucumber, and pumpkin has been described.30-32 Unlike the other members of the Cucurbitaceae family, pumpkin seed is not a common cause of food allergy, and there have been few reports of allergic reactions after ingestion.33,34
Adverse reactions and severe toxicity have not been reported with the use of Cucurbita extracts. Studies of C. maxima ingestion indicate that seeds of C. max are not toxic for rats and swine.35
