“…The nutritional properties of Cape gooseberry are shown in Table 1. These values showed some non-significant differences with P. peruviana cultivated in the southern African region and Argentina [4,26]. This research showed that cultivated Cape gooseberry from the Andean region of the Atacama Desert favored the content of calcium, sodium, and phosphorus, compared to other reports for the same fruit grown in producing countries [3,4].…”

Physalis peruviana L. belongs to the Solanaceae family and produces a spherical fruit used to treat various diseases. However, the chemical composition, nutritional characterization, and bioactive properties of the P. peruviana growing in the Andean region of the Atacama Desert have not been conducted so far. The results showed clear differences in the nutritional and bioactive characteristics of the fruits grown in arid environmental conditions, which were comparable to those from countries with a production tradition. The fruits studied showed a higher Ca, Cu, Mn, P, and Zn content and bioactive compounds such as flavonoids and tannins than those reported in the literature. UHPLC was performed to determine the main phenols. Gallic acid was identified as the predominant phenolic compound in this species (303.63 mg/100 g FW), of which to our knowledge no previous study has reported similar concentrations in this species. Moreover, Cape gooseberry extract has antioxidant and antimicrobial activity against Gram-positive and Gram-negative bacteria. Pseudomonas syringae (MIC 0.313 mg/mL and MBC 1.25 mg/mL) was the most susceptible bacterium. Meanwhile, Erwinia rhapontici was the most resistant bacterium (MIC and MIB 5.00 mg/mL). Furthermore, it was found to inhibit α-amylase activity with an IC50 value (39.28 µg/mL) similar to that of acarbose (35.74 µg/mL). These results expand the knowledge of the species cultivated in arid environmental conditions and suggest an alternative for the potential use of this fruit to manage chronic diseases such as diabetes.

“…Byrsonima crassifolia (254 mg gallic acid/100 g DFW) (Gordon et al, 2011). The total polyphenol content in Ripe H. edulis fruits (yellow fruits) was comparable to that found in Sclerocarya birrea (700 to 2500 mg gallic acid/100 g DFW) (Nitcheu et al, 2017), and lower than Pouteria macrophylla (2915 mg gallic acid/100 g DFW) (Gordon et al, 2011). The highest DPPH radical scavenging activity in Unripe fruits could be related with the highest total polyphenol concentration.…”

“…For example, in South Africa, the fruits are consumed by various ethnic groups. Besides, fruits are processed to make jam, jelly and other products and, are presented to be one product with a potential to be developed into new food or beverage products with high nutritional values in South Africa and Zimbabwe (Van Wyk, 2011; Ngadze et al, 2017;Nitcheu Ngemakwe et al, 2017;Mashile et al, 2019). This situation is the same in some countries like Nigeria and Botswana where fruits are, in addition, used to fight famine in rural areas and are presented to be a good candidate for introduction in the crop systems.…”

Background: Most of the people living in developing countries rely on local remedies from traditional medicines to take care of their healthcare needs. In recent years, the use of medicinal plants increased considerably. Consequently, studies on medicinal plants are necessary to produce more effective drugs with fewer side-effects. This work aims to compile the dispersal data on Strychnos spinosa Lam., a medicinal plant with great therapeutic potential in traditional medicine, on its ethnobotanical uses, chemical compounds, as well as its pharmacological and nutritional effects. Material and Methods: To achieve the aforementioned aim, electronic databases such as Pubmed, Science Direct, Google scholar, Scopus and SciFinder were scanned. Results: Literature survey revealed that S. spinosa is used in the treatment of microbial infections, malaria, trypanosomiasis, intestinal worms, tuberculosis, infertility, gastrointestinal disorders, snake bite, hypertension, and diabetes mellitus among other ailments. The plant is also used as food material. S. spinosa contains many chemical compounds, such as alkaloids, terpenes, sterols, fatty acids, flavonoids, saponin, and others. The fruits are a source of important nutrients such as carbohydrates, sugars, proteins, vitamins and fibres. Experimental studies have shown numerous pharmacological properties, including antimicrobial, antiplasmodial, anti-trypanosomal, anti-leishmanial, anti-nematicidal, anti-inflammatory, anti-oxidant, antidiabetic and other activities. Conclusion: This review article provides comprehensive information on S. spinosa and its various extracts. Due to the promising effects of the plant extracts on various diseases and its nutritional values, there is a need for toxicity studies and clinical trials to assess the effects of its identified bioactive compounds.
