“…The percentage carbohydrate observed from the proximate analysis of the seed cotyledons was 67.65 % as displayed in table 4. The value is significantly higher than 60.39% previously reported by [27] but lower than 70.60% and 71.40% respectively reported [25,26]. These analysis shows that the C. albidum seed can serve as food and can also give energy as it is a very good source of carbohydrate.…”

The anti- microbial activity tests of the seed oil, NaOH and ash soaps of the seed oil, of C.albidum were carried out to determine their effectiveness against gram+, gram– bacteria and some fungi strains. The proximate analysis of C.albidum seeds was performed to determine its nutritional benefits to mankind. Agar diffusion tests using Disc diffusion for the pure oils and soaps while the cup plate test method for dilutions was used in the determination of in-vitro activities. Standard methods as described by AOAC, (1990); AOAC, (1984) and Kjeldahl method described by Chang (2003) were used for proximate determinations. The results show the activity of the oil against Klebsiella pneumonia at a concentration as low as 10 mg/ml. The ash-soap of the leaves shows the highest antimicrobial activities because its MIC is the closest to the standard, Streptomycin. It possesses activity against Escherichia coli and Klebsiella pneumonia at a concentration as low as 5mg/ml. The % proximate analysis composition shows Moisture content, Ash content, Crude Fibre, fat/Oil, Protein, Carbohydrates as follows (14.98, 1.90, 2.09, 2.38, 12.14 and 67.65)%. The study concluded by unleashing the great potential of Chrysophyllum albidum seeds as a useful raw material in food, cosmetics and pharmaceutical industries rather than being regarded as waste in the environment

Fruits, due to high moisture content, deteriorate quickly when not adequately preserved. Drying, a common preservation method, will affect quality of final product if not properly controlled. Pretreatments prior to drying have been established as a way of retaining product qualities. This study investigated the effect of pretreatments on the qualities of dried African star apple flesh. African star apple fleshes were sliced (2, 4, 6 and 8 mm) and subjected to pretreatments [blanching (80 ºC for 3 min), lime juice (100%), ascorbic acid and salt solution (1:25 w/v)]. Untreated samples served as control. Samples were dried in cabinet dryer (50, 55 and 60 ºC) at 2 m/s constant air flow-rate, monitored at intervals, until constant weight was obtained. Ascorbic acid and colour measurement of the fresh and dried sample were determined using standard method. The moisture contents of the African star apple flesh were observed to reduce from a mean value of 70.44%, 71.55% and 73.24% to 2.38%, 1.91% and 3.23% at temperatures of 50, 55 and 60 °C, respectively. The total drying time ranged between 7 to 8 h. Colour of the dried African star apple was significantly preserved by the pretreatments used, and low overall color change (ΔE) was obtained at the lowest drying temperature (50oC). The ascorbic acid and lime pretreatments however had better colour overall. Lime pretreatment for 2 mm thick at 50ºC gave the best result in terms of ascorbic acid retention. Hence, lime juice pre-treatment has potentials of retaining quality of dried fruits. Citation | Komolafe, O.M.; Hussein, J. B.; Adebayo, Q.; Abiona, O.O.; Oke, M.O. (2019).

This study sought to evaluate the added advantage of mediating ZnO nanostructures with a medicinal plant. The synthesized ZnO nanocrystalline structures were confirmed by Fourier transform infrared spectrometer and characterized through scanning electron microscope, transmission electron microscope, ultraviolet–visible spectroscopy, and energy-dispersive X-ray spectrometer. The antioxidant, anti-inflammatory, and antimicrobial activities of the ZnO nanostructure mediated with methanol extracts of the leaf, fruit, and seed of Chrysophyllum albidum were then evaluated using DPPH assay, egg albumin denaturation assay, and agar well diffusion methods, respectively. All the characterization analyses revealed high-purity hexagonal-shaped ZnO nanoparticles which were agglomerated. The mean diameter of the particles determined were 11.3 ± 1.7 nm , 20.4 ± 3.2 nm , and 27.3 ± 6.6 nm for C. albidum seed, fruit, and leaf extract-mediated ZnO NPs, respectively. The EC50 values recorded for the antioxidant activity of the extract-mediated ZnO NPs were 0.507 ± 0.015 , 0.255 ± 0.006 , 0.193 ± 0.003 , and 0.004 ± 0.000 mg/mL for leaf, fruit, seed, and ascorbic acid, respectively. From the antimicrobial analysis, C. albidum seed extract-mediated ZnO NPs recorded the highest zone of inhibition ( 24.33 ± 0.47 ) against S. aureus whereas C. albidum leaf extract-mediated ZnO NPs gave the lowest zone of inhibition ( 13.00 ± 1.41 ) against E. coli at a concentration of 50 mg/mL. Moreover, C. albidum fruit extract-mediated ZnO NPs presented the highest zone of inhibition ( 18.00 ± 0.82 ) against the fungus (C. albicans) also at a concentration of 50 mg/mL. The IC50 values recorded for the anti-inflammatory activity of the extract-mediated ZnO NPs showed inhibition in the order fruit > seed > leaf . Meanwhile, extracts of the samples showed the presence of flavonoids, alkaloids, saponins, and glycosides as phytochemical constituents in the leaf, fruit, and seed samples. In conclusion, the synthesized ZnO NPs from the extracts of C. albidum displayed significant antioxidant, anti-inflammatory, and antimicrobial activities against some selected microbes and fungi.
