Red-fleshed dragon fruit offers an array of bioactive compounds. Its cultivation is gaining
momentum in India, including in arid and semi-arid conditions. Among various factors, the fruit
developmental stages and climatic conditions of locations greatly influence the biosynthesis and
actual contents of different bioactive compounds and mineral contents of the fruit. The changes in
physical attributes, and bioactive and mineral content in red-fleshed dragon fruit grown in semi-arid
conditions in India were assessed and quantified at six developmental stages. Significant changes
occurred in the physical attributes of the fruit and the bioactive compounds and mineral content
during the fruit maturation stages of the red-fleshed dragon fruit. The fruit physical characteristics,
such as fruit size, fruit and pulp weight gain, peel thickness, and fruit firmness, along with eating
quality parameters, such as soluble solids, sugars, acidity and soluble proteins, were observed at
optimum at 35 days after anthesis (DAA). The decrease in total phenolics (29.96%), total flavonoids
(41.06%), and vitamin C (75.3%) occurred throughout the fruit development stages, whereas the
content of betalains, which was detected initially at 25 DAA, increased (48.6%) with the progression of
the fruit development stages. However, the antioxidant capacity and free radical scavenging activity
demonstrated variable trends throughout the fruit maturation period. There was an increasing trend
in all the minerals up to 35 days, followed by a slight decrease, except for phosphorus content,
which increased until the last stage of evaluation. The colour characteristics, in conjunction with
the bioactive and antioxidant potential determined in the present study, suggest that red-fleshed
dragon fruit can be harvested at 35 DAA for long-distance transportation, and from 35 to 40 DAA for
local marketing.
