| Summary: | Recently, antioxidants derived from natural sources have gained wide interest worldwide due to their
high medicinal values and industrial applications. Various factors have been reported to affect the
antioxidant content in plants. This study aimed to analyze the effect of seedling size and flowering
time on quality attributes and bioactivity of pineapple fruits, Ananas comosus L. var. Yankee. Free
radical scavenging activities of the fruits produced from seedlings of different sizes (grades A, B and
C), produced either through natural flowering or artificially induced flowering were investigated using
DPPH, ABTS and FRAP assays. The methanolic extract of fruits from grade A seedlings showed the
lowest IC50 value of ABTS radical and the highest FRAP value, indicating good scavenging activity.
However, DPPH assays showed that fruits from grade C seedlings (either naturally produced or
artificially induced) exhibited the highest scavenging activity against DPPH, compared to fruits from
other seedling grades. Moreover, fruits from grade B seedlings produced from natural flowering
showed significantly better antioxidant potential than fruits that were artificially induced. Other quality
attributes such as fruit weight and length, total titratable acidity (TTA), amount of total soluble solid
(TSS) and pH were also observed to be not significantly different among fruits produced from
different seedling sizes, and their phytochemical constituents were also similar. These results
suggested that A. comosus L. var. Yankee fruits contain various pharmacologically important
phytoconstituents which can be further exploited for various uses. |
