Chemical composition of a seed kernel of a pumpkin produced in the Central Chernozem region of Russia

Abstract Seeds are the by-product in the cultivation of pumpkin. They are characterized by a high level of mineral substances and essential oils. However, the level of accumulation of biologically active components of seed kernel varies greatly among pumpkin varieties depending on climatic cultivation zones. Pumpkin varieties – Vitaminnayanaya, Michurinskaya sladkaya, Kubyshka, Muskatnayanaya, Aport – are taken as the objects of study. The chemical analysis of pumpkin seed kernels was carried out in accordance with generally accepted methodological recommendations. It was found that the sodium content in pumpkin seed kernel in the varietal section varies within the range of 5.07-17.6 mg/100 g, potassium – 554.8-767.1 ml/100g, calcium – 156.6-989.0 ml/100g, magnesium – 125.5-323.8 ml/100g, iron – 2.31-6.92 ml/100g, copper – 0.384-0.697 ml/100g, zinc – 4.80-7.43 ml/100g. The kernels of pumpkin seeds of the Michurinskaya sladkaya variety are characterized by high level of calcium – 989 ml/100g. Pumpkin seed kernels zoned in Tambov Region are rich in essential linoleic acid (52.59-63.87%), polyunsaturated oleic acid (11.70-27.35%), tocopherol (90-140 ml/100g). According to the content of linoleic acids, the highest indicators were found in seeds of Aport varieties – 63.87%, oleic acids – Muskatnayanaya (27.35%). The high content of tocopherol is typical for seeds of the Michurinskaya sladkaya variety – 140 ml/100 g.

Oilseed pumpkin seeds are known to be rich in oil and nutrients. Their content in bioactive components gives them some assets that make them beneficial for human health. Although commonly consumed as a snack, pumpkin seeds are ready to claim more uses. The identification of pumpkin species is a major resource in this study. Thus, we worked with three pumpkin species: Cucurbita maxima (CMa), Cucurbita moschata (CMo) and Cucurbita pepo (CP). The species effect on the chemical composition, the content of bioactive compounds and the antioxidant activity was studied. As a result, the analysis of pumpkin seed oil revealed a polyunsaturated fatty acids (PUFAs) content ranging from 52.23% to 57.65%. Our study also revealed that this oil was a good source of phenolic compounds, in particular CMa with a value of 27.52 mg gallic acid equivalents per gram of methanolic extract and 633.51 mg/kg of total tocopherols, which gives it a very strong antioxidant character. In addition, it showed a high antioxidant potency (126.20 ± 20.44) μg/ml for CMa. In this respect, it can be said that the species effect can be a very important factor influencing the nutritional quality of pumpkin seed oil.
