Total Vitamin C, Ascorbic Acid, Dehydroascorbic Acid, Antioxidant Properties, and Iron Content of Underutilized and Commonly Consumed Fruits in Sri Lanka

Syzygium jambos L. belonging to the family Myrtaceae has a long history of using as a dietary fruit and folklore medicine. Investigation of this fruit was carried out to evaluate the different chemical properties and biological activities. The moisture and ash content of the fruit sample were calculated as 86.88 ± 0.61% and 0.29±0.02%, respectively. Dried powder of the fruit was extracted successively with nhexane, dichloromethane (DCM) and methanol (MeOH). UV-Visible and FT-IR spectral analyses confirmed the presence of unsaturated carboxylic acid in n-hexane, unsaturated ester in DCM and a diketone in MeOH extracts. Cytotoxicity assay of different extracts was carried out against HeLa and Vero cell lines and no extract was found to be cytotoxic. Total phenolic contents of the n-hexane, DCM and MeOH extracts were 15.39 ± 0.24, 31.32 ± 0.25 and 42.19 ± 0.16 mg gallic acid equivalent per gram of dry extract, respectively and total flavonoid content of n-hexane, DCM and MeOH extracts were 6.52 ± 0.18, 15.55 ± 0.16 and 8.36 ± 0.16 mg quercetin equivalent per gram of dry extract, respectively. This study establishes that S. jambos fruit can be a potential source of natural antioxidants. Bangladesh Pharmaceutical Journal 24(2): 111-116, 2021

“…Evaluation of vitamin C synthesis: To determine the presence of Vitamin C AOAC titrimetric method was used as explained by Nielsen. Five milliliter of fungal extract was titrated with DCPIP reagent, appearance of distinct light pink color for more than 5 seconds confirms the presence of vitamin C, experiment was performed in triplicates and ascorbic acid expressed as mg of L-ascorbic acid equivalents (AAE) per 100 g of fresh weight of the fungus (Abeysuriya 2020). Metal chelating activity: Metal chelating activity was determined by method described by Chew et al 2009.…”

is one of the versatile and important mushroom funguses, used in numerous applications. This study Schizophyllum commune explored the occurrence and molecular identification of in ravine soils and their potential applications with Schizophyllum commune pharmaceutical importance. During cultivation studies the mushroom isolate exhibited moderate growth in used compost. The fungal isolate produces alkaloids, flavonoids and vitamin C which are useful in various applications, Fe metal Chelation and DPPH free radical scavenging activities were also investigated. The maximum Fe metal chelation activity was 69.32% whereas the maximum inhibition of free radical was 41.86%. Extracellular bioactive molecules of this strain under stationary phase were identified by Gas chromatography Mass Spectroscopy (GCMS). Polysiloxanes are the major compounds out of which cyclohexasiloxane is the major contributor with 57.17% of total. Through this study it could be concluded that the isolated fungal strain ns29 has many medicinal properties that could be a base Schizophyllum commune for further studies and cyclohexasiloxane made this isolated industrial potable because it is used in various cosmetic formulations.

“…About 29 locally grown Minor fruits (MFs) were used in this study (Table 1). For comparison of the selected parameters, three Common fruits (CFs) were used which were chosen based on our previous study (19). Carica papaya, Mangifera indica and Psidium guajava were selected as the top three CFs.…”

“…Some studies on underutilized fruits for their antioxidant capacity are highlighted by several authors (10−18). Recently, we have reported a comparative study on total vitamin C contents, antioxidants capacities and iron content of some underutilized fruits, with commonly consumed fruits (19). However, no adequate scientific reports are available on Sri Lankan minor fruits for their nutritional and biochemical properties especially on iron content, total vitamin C, dehydroascorbic acid HORIZON e-Publishing Group contents and antioxidant capacities.…”

Sri Lanka is a habitat of diverse fruit varieties; nevertheless 95% of them are underutilized by people due to unawareness of their nutritional values and health aspects, and hence become ‘minor fruits’. This study was aimed on revealing vitamin C, iron and antioxidant contents of 29 varieties of minor fruits (MFs) with the comparison of the same with three best commonly consumable fruits (CFs), namely Carica papaya, Mangifera indica and Psidium guajava. Ascorbic acid (Asc), dehydroascorbic acid (DAsc), vitamin C (TC), phenolic (TP), flavonoid (TF), iron (Fe) contents and antioxidant capacities (AOCs) of fruits were determined using standard methods. The results of mean Asc, DAsc, TC, TP, TF and Fe contents in 100 gm of MFs ranged from 3.1 to 121.5 mg, 1.2 to 70.7 mg, 6.6 to 136.1 mg, 24.9 to 1613.3 mg Gallic acid equivalent, 6.2 to 228.0 mg Quercetin equivalents and 0.2 to 4.9 mg respectively. DPPH and Ferric Reducing Antioxidant Power (FRAP) assays were used for AOCs and variation of IC50 values in a DPPH assay was 1.2 to 245.4 mg/ml whereas FRAP values ranged from 9.6 to 486.7 ?mol FeSO4/gm. Among the studied minor fruits, Melastoma malabathricum (Maha bovitiya/ Malabar melastome) is found as the best respect to all considered parameters. As a conclusion, it can be stated that, the Sri Lankan minor fruits are good alternatives to the common fruits as they are recognized as good source of vitamin C, iron and higher content of antioxidants. As an outcome, Sri Lankan minor fruits can be promoted as alternatives to common fruits and as source of revenue for national economy.
