Nutritional characterization and antioxidant properties of various edible portions of Cucurbita maxima: A potential source of nutraceuticals. Heliyon 2023; 9:e16628. [PMID: 37303524 PMCID: PMC10248113 DOI: 10.1016/j.heliyon.2023.e16628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 05/08/2023] [Accepted: 05/22/2023] [Indexed: 06/13/2023] Open
Abstract
Pumpkin (Cucurbita maxima) is a widely grown vegetable in Bangladesh and is known as the sole supplier of various nutrients. Many studies evidence the nutritional value of flesh and seed while peel, flower, and leaves were reported scarcely with limited information. Therefore, the study aimed to investigate the nutritional composition and antioxidant properties of flesh, peel, seed, leaves, and flowers of Cucurbita maxima. The seed had a remarkable composition of nutrients and amino acids. Flowers and leaves possessed higher content of minerals, phenols, flavonoids, carotenes, and total antioxidant activity. The order of IC50 value (peel > seed > leaves > flesh > flower) indicates higher DPPH radicals scavenging activity of the flower. Moreover, a significant positive relationship was observed among these phytochemical constituents (TPC, TFC, TCC, TAA) and DPPH radicals scavenging activity. It could be concluded that these five parts of the pumpkin plant have an intense potency to be an exigent component of functional food or medicinal herbs.

Habte G, Tamiru S, Eyasu K. In vivo antimalarial activity of the 80% methanolic crude fruit extract of Lagenaria siceraria (Molina) Standl. against Plasmodium berghei infected mice. Heliyon 2023; 9:e15453. [PMID: 37151678 PMCID: PMC10161574 DOI: 10.1016/j.heliyon.2023.e15453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/28/2023] [Accepted: 04/10/2023] [Indexed: 05/09/2023] Open
Abstract
Background Malaria is a public health menace. Resistance to therapeutic armamentarium is impeding its control. Therefore, research targeting the discovery of novel antimalarial drug arsenals is a priority. The important point to begin the search for such drugs is the folkloric medicinal plants. Ripe fruit of Lagenaria siceraria is bored, rinsed with cold water, and one glass is used as a drink early in the morning for the treatment of malaria in Ethiopian folk medicine. In vivo antimalarial efficacy of the plant was not affirmed scientifically, though. Consequently, the present study was conducted to assess the in vivo antiplasmodial effect of Lagenaria siceraria in P. berghei infected mice. Methods The fruits were extracted using 80% methanol in water. Acute toxicity test was conducted on the extract. Secondary phytochemicals were assessed. The four day suppressive test was employed in mice infected with P. berghei. Thirty mice were grouped in to five and inoculated with P. berghei. After 3 h, three of the groups received the extract at doses 100, 200 and 400 mg/kg. The remaining groups served as negative (2% Tween80) and positive control (chloroquine). Parasitemia, packed cell volume, weight, temperature and survival time were monitored. SPSS version 22 was used for data analysis. Results No toxicity was seen in mice. The crude extract elicited significant suppression (p < 0.05) of the parasite compared to the negative control. The highest parasite suppression (77.37%) was measured at the upper dose. Furthermore, the crude extract significantly (p < 0.05) prevented body weight loss, anemia, reduction in temperature and prolonged the survival time compared to the negative control. Conclusion This study asserted that the fruit of Lagenaria siceraria is enriched with in vivo antimalarial activity. Hence, further in depth antimalarial investigations on the plant is strongly recommended.

Tropical Vegetable Oils Do Not Alter Growth Performance in African Catfish through a High n-6 Polyunsaturated Fatty Acids Biosynthesis Capacity. Lipids 2019; 54:329-345. [PMID: 31006877 DOI: 10.1002/lipd.12145] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 02/14/2019] [Accepted: 03/01/2019] [Indexed: 01/03/2023]
Abstract
The main objective of this study was to determine the best vegetable oils (VO) for nutrition of African catfish by assessing the effects of a complete replacement of fish oil (FO) by different VO sources on its growth performance, fatty acid composition, and elongase-desaturase gene expression levels. Fish (16.2 g of initial body weight) were fed with five experimental isonitrogenous, isolipidic, and isoenergetic diets in which FO was totally replaced by cottonseed oil (CO), palm oil (PO), desert date oil (DO), or Shea butter (SB). Complete replacement of FO with VO did not affect growth performance except for low values in fish fed SB diet. Muscle n-3 LC-polyunsaturated fatty acids (PUFA) were significantly reduced in fish fed VO-based diets when compared with FO fed fish. However, the muscle arachidinic acid (ARA) levels in phospholipid class were 1.4 to 1.6 times higher in fish fed CO and DO diets than FO fed fish despite the lower ARA suppliers from these VO-based diets, suggesting endogenous LC-PUFA biosynthesis from PUFA precursors in fish fed these VO. The fads2 and elovl5 gene expression levels in liver of fish fed DO were also higher compared to FO controls. Therefore, all the results support the hypothesis that African catfish has higher biosynthesis capacity to convert vegetable n-6 PUFA precursors like linoleic acid (LNA, 18:2n-6) into n-6 LC-PUFA of the ARA type, compared to the conversion of vegetable α-linolenic acid (ALA, 18:3n-3) into n-3 LC-PUFA of the eicosapentanoic acid (EPA) or docosahexanoic acid (DHA) type. The results also indicate that DO can be recommended as the best alternative to FO replacement in African catfish nutrition.
