“…Spinach leaves (Spinacia oleracea) had β-carotene in the range of 2966-3967 µg/100 g with the average value 3468 ± 296 µg/100 g. In Indian Food Composition Tables (IFCT) [7], the β-carotene content of spinach has been reported as 2605 ± 521 µg/100 g. The results of the present study were similar to the previously reported results ranging from 3000 to 5000 µg/100 g [8][9][10][11][12][13]. However, higher amounts of β-carotene in spinach leaves have also been reported ranging from 5000 µg/100 g to 152100 µg/100 g [14][15][16][17][18][19].…”

Most of the vitamin A in the diet comes from plant food sources in developing countries. This study was designed with an objective of determining β-carotene content of a total of 26 types of green leafy vegetables, tubers, other vegetables and fruits obtained from four wholesale markets in Delhi, India using HPLC. There was a wide variation in β-carotene content of green leafy vegetables, with means ranging from 2199 µg/100 g in Basella rubra to 7753 µg/100 g in Amaranthus gangeticus. A large variation was observed in β-carotene content of fruits and the mango varieties tested, ranging from undetectable levels in strawberry and 808.60 µg/100 g in totapuri mango up to 11789 µg/100 g in alphonso mango. Approximately 65 g and 100 g of a green leafy vegetable would meet daily requirement of a preschooler and older child/adult respectively. Mango has considerable amount of β-carotene, and consuming a medium-sized bowl by preschool children would meet 99% of Recommended Dietary Allowances (RDA). The information generated is useful in identifying types of fruits and vegetables with higher concentration of the provitamin A in low income economies where fruits and vegetables are expensive. Individuals need to consume only small quantities of these vitamin A rich foods to meet daily requirement.

“…Charoensiri et al [40] reported only 471 μg/100 g edible portions. Tee and Lim [41] in the study on carotenoid composition and content of Malaysian vegetables and fruits reported 228 μg /100 g edible portions of beta carotene in ripe papaya. Malaysian papaya has almost equivalent beta carotene value to that of Thai Food (1043 μg/100 g edible portions) [40].…”

This study aimed to characterize the different parts of Carica papaya (ripe and unripe papaya, leaves and seed), through their proximate composition, total antioxidant activity, and in vitro antiproliferative activities. Both macronutrients and micronutrients were determined using standard AOAC methods of analysis, while vitamin analyses were determined by High Performance Liquid Chromatography (HPLC). Results showed that the ripe papaya had the highest antioxidant activity (84.04%) followed by unripe papaya (81.35%), leaves (78.03%) and the least was seed (75.35%).The phenolic content was in the order of leaves>unripe papaya>ripe papaya>seed. HPLC analysis showed that papaya leaves exhibited the highest ascorbic acid and β-carotene content (85.60 and 3.86 mg/100 g respectively), while the seeds had the highest Vitamin E content (4.09 mg/100 g). Results obtained from cytotoxic activities showed that MCF-7 (hormone dependent breast cancer) and MDA-MB-231 (non-hormone dependent breast cancer) cell cultures were significantly inhibited by the extract. The antioxidant and antiproliferative activities of different parts papaya extracts indicate that the consumption of the whole fruit, ripe and unripe papaya, leaves and the seed supplies the important quantities of numerous necessary nutrients for human diet which includes vitamins A, C and E.

Current knowledge on the basic radionuclide tolerance indicates that plants may develop mechanisms preventing the damaging effects of radionuclide stress. The radionuclides content was determined in the Mediterranean coastal black sand soil and in the edible portions of the four food crop plant species, viz., Eruca sativa, Lycopersicon esculentum, Pasidium guajava and Mangifera indica. Biochemical and nutritional constituents were assessed to elucidate the possible effect of radionuclides on the edible portions of the plants. The ability of the four study plant species to accumulate Uranium and Thorium in their edible portions from the coastal black sand soil is higher than that absorbed from the inland agricultural soils. The nutritional constituents were affected by the high concentrations of Uranium and Thorium in the plant tissues. The total protein, moisture content, total phenolic compounds, total chlorophyll, total carotenoids, β-Carotene and Lycopene were positively correlated with Uranium and Thorium concentrations in the plant tissues, while the mineral content, vitamin C and total flavonoids were suppressed by high concentrations of Uranium and Thorium in the plant tissues. The fluctuations in the biochemical or nutritional constituents of the plant edible portions are considered an important defense mechanism to control the redox state of the cells accumulating radionuclides with high levels.
