“…In the methanolic extract of the seeds it was possible to suggest the presence of three compounds: linoleic acid (2, Rt = 66 min) at m/z = 279.59, palmitic acid (3, Rt = 68 min) at m/z = 281.27, and stearic acid (4, Rt = 71.5 min) at m/z = 283.72. These compounds have already been reported to be present in A. squamosa seeds according to the literature [11,31,33]. Chemical structures of the identified compounds are presented in Figure 1.…”

“…Studies by Huang and collaborators [16] found the vitamin C and carotenoids content in A. squamosa seeds was 10.8 ± 0.56 µmol/g DW and 6.6 ± 0.37 µg β-carotene/g DW, respectively, in the pulp the vitamin C content was 8.1 ± 0.16 µmol/g DW and carotenoids 6.4 ± 0.29 µg β-carotene/g DW; the values found for the seed in the present studies are higher. Some other works also quantified vitamin C and carotenoids in the pulp of A. squamosa with results of 29.6 ± 0.9 µmol/g dry weight, 21.43 ± 4.99 µmol/g dry weight, 31.22 ± 0.15 mg/100 mL for vitamin C and 2.97 ± 0.64 mg βcarotene/g dry weight for carotenoids [11,27,28].…”

“…In addition to nutritional benefits, A. squamosa pulp can be used as antioxidant, antidiabetic, hepatoprotective, and antitumor agents, including activities related to alkaloids, fixed oils, tannins, and phenolic compounds present in its chemical composition [10]. The highest nutritional value is in the seed, with high protein content, high oleic, and linoleic acid value, thus making it a possible nutritional implementation in human food [11]. The aim of the present study was to chemically evaluate methanolic extracts of the pulp and seeds of A. squamosa, their antioxidant effect, and their potential for acetylcholinesterase inhibition.…”

This study presents the chemical profile of extracts from the pulp and seed of Annona squamosa L., as well as the evaluation of their antioxidant and acetylcholinesterase inhibition activities. In the chemical prospection, qualitative assays were performed, and the contents of total phenols, flavonoids, vitamin C, and carotenoids were quantified. For the compounds identification, analyses of the extracts were performed by liquid chromatography coupled to mass spectrometry. Antioxidant evaluation was performed using the DPPH, ABTS, Fe3+ reduction, 2-DR protection, and β-carotene protection methods. The assay for inhibition of acetylcholinesterase activity was determined using the method described by Ellman. The secondary metabolites identified were anthocyanidins, flavones, flavonols, and alkaloids. Phenol analysis showed a higher quantitative value of total phenols and flavonoids for the seed extract, and the vitamin C content was higher in the pulp extract. There was no significant difference in relation to the carotenoids quantification. The best results obtained for antioxidant activity, for both seed and pulp extracts, were with the ABTS method with IC50 of 0.14 ± 0.02 and 0.38 ± 0.02 mg/mL, respectively. Compared to A. squamosa seed extract, the pulp extract demonstrates higher AChE inhibitory activity with IC50 of 18.82 ± 0.17 µg/mL. A. squamosa is a nutritious food source. The continuity of the studies is fundamental to relate the consumption of this food and its effects on neurodegenerative diseases.

“…The use of by-products originating from the food industry has naturally increased and is taking part in the supplementation of animal feed. To that end, soursop seed also has potential for this branch of the industry, since it has antinutritional compounds such as phytate, tannin, and cyanide, but at low concentrations [ 91 , 92 ].…”

The increased international interest in the properties of soursop (Annona muricata) alerts us to the sustainability of productive chain by-products, which are rich in phytochemicals and other properties justifying their industrial application in addition to reducing the environmental impact and generating income. Chemical characteristics of soursop by-products are widely known in the scientific community; this fruit has several therapeutic effects, especially its leaves, enabling it to be used by the pharmaceutical industry. Damaged and non-standard fruits (due to falling and crushing) (30–50%), seeds (3–8.5%), peels (7–20%), and leaves, although they constitute discarded waste, can be considered as by-products. There are other less cited parts of the plant that also have phytochemical components, such as the columella and the epidermis of the stem and root. Tropical countries are examples of producers where soursop is marketed as fresh fruit or frozen pulp, and the valorization of all parts of the fruit could represent important environmental and economic perspectives. Based on the chemical composition of the fruit as well as its by-products and leaves, this work discusses proposals for the valorization of these materials. Soursop powder, bioactive compounds, oil, biochar, biodiesel, bio-oil, and other products based on published studies are presented in this work, offering new ideas for opportunities for the regions and consumers that produce soursop.

“…Annona squamosa L. is a kind of tropical fruit, commonly known as Custard apple in English and Sharifa in Hindi, which belongs to Annonaceae family and introduces to China for centuries (Adam Yahya Abdualrahman et al, 2019). Like some other fruits, A. squamosa with high carbohydrate content was gradually ripened and softened with cracking and browning within a few days stored at room temperature (Baskaran et al, 2016; Ren et al, 2020).…”

In this study, the effects of postharvest treatment with 1% pullulan, 2% calcium chloride, and 1% chitosan on the physiological and biochemical properties, enzymatic activities and the differentially expressed genes (DEGs) with sucrose metabolism of Annona squamosa L. fruits stored at 15 ± 1°C for 12 days were investigated. Exogenous substances treatment retained a higher level of firmness, surface color, total soluble solids, organic acids, and tvolatile flavor substances compared to the control fruit. Exogenous substances treatments, particularly calcium chloride, enhanced sucrose phosphate synthase activity, whereas it inhibited acid invertase (AI) and neutral invertase (NI) activities. These changes in enzyme activities together resulted in a significantly higher sucrose content and lower glucose and fructose contents. The number (1550 genes), proportion (6.46%), and expression levels of DEGs in the calcium chloride‐treated fruit, which was enriched in the starch and sucrose metabolism pathways, were all significantly higher than in chitosan treatment. The findings indicated that exogenous calcium chloride might alter sucrose metabolism during fruit ripening by regulating the enzymatic activities and metabolism pathway. This will provide a theoretical basis for further research on the regulation of sugar metabolism by exogenous substances treatment to solve the problem of quality degradation in the storage of A. squamosa. Novelty impact statement This study indicated that the application of chitosan, pullulan, or calcium chloride, especially calcium chloride treatment, can effectively maintain the quality of Annona squamosa fruit during storage. It was found that exogenous calcium chloride might alter sucrose metabolism during fruit ripening by regulating the enzymatic activities and metabolism pathway. The results provided a theoretical basis for exploring the mechanism of exogenous substances for maintaining the postharvest quality and enhancing the shelf life of A. squamosa fruit in further research.
