“…The average results obtained from the measurement of morphological variables of C. foetidissima and C. radicans fruits sampled in the wild are shown in Table 1. Regarding C. foetidissima, they complement previous studies describing the morphological variability of fruits obtained from plants sampled in the wild in Arizona and elsewhere [3]. Several differences in morphological variables were found between fruits of C. foetidissima and C. radicans.…”

“…Notable progress has been made in the overall characterization of many of these plants. However, knowledge regarding several non-forest herbaceous plant species that have the potential to be exploited for commercial use, such as Cucurbita foetidissima Kunth and C. radicans is limited [2][3][4]. Cucurbita foetidissima is part rich in starch content, may be used for human or animal nutrition [3,22].…”

“…The former is based on evidence showing that the root starch of C. foetidissima produced superior ethanol yields compared to corn or sorghum grains [16,17,19,[23][24][25]. The seeds, known to reach yields that approximate 3000 kg/ha [18], contain high amounts of protein and superior-quality oil similar in composition to sunflower oil [2,3,17,19,26]. Conversely, C. radicans develops multiple small and tuberous ovoid roots rather than an extensive taproot system [13].…”

“…However, the attractiveness of C. foetidissima as a potentially lucrative cash crop has been hampered by their highly inconsistent plant growth and fruit yields produced in response to fluctuating ambient conditions, predominantly in terms of solar radiation and rainfall levels, in addition to the presence of competing species [3,16,19]. Likewise, the very limited knowledge regarding the chemical composition and growth habits of C. radicans has obstructed its consideration for more extensive cultivation outside small pockets in the states of Jalisco, Michoacán and rural zones of Mexico City [4,5].…”

Cucurbita foetidissima and C. radicans are scarcely studied wild pumpkin species that grow in arid and semi-arid areas of Mexico and the United States. This study describes the morphological, proximal composition, metabolic finger-prints and seed protein profiles of C. foetidissima and C. radicans fruits collected in the wild during a one-year period in different locations of central-western Mexico. The results obtained complement the limited information concerning the fruit composition of C. foetidissima and greatly expand information in this respect regarding C. radicans. Morphology and proximal composition of their fruits varied significantly. Different metabolic fingerprints and seed protein profiles were detected between them and also with the chemical composition of domesticated Cucurbita fruits. The neutral lipids in seed, pulp and peels were rich in wax content and in unsaturated compounds, probably carotenoids and tocopherols, in addition to tri-, di- and mono-acylglycerols. The tri- and diacylglycerol profiles of their seed oils were different from commercial seed oils and between each other. They also showed unusual fatty acid compositions. Evidence of a possible alkaloid in the pulp and peel of both species was obtained in addition to several putative cucurbitacins. An abundance of phenolic acids was found in all fruit parts, whereas flavonoids were only detected in the peels. Unlike most cucurbits, globulins were not the main protein fraction in the seeds of C. radicans, whereas the non-structural carbohydrate and raffinose oligosaccharide content in their fruit parts was lower than in other wild cucurbit species. These results emphasize the significantly different chemical composition of these two marginally studied Cucurbita species, which was more discrepant in C. radicans, despite the notion regarding C. foetidissima as an aberrant species with no affinity to any other Cucurbita species.
