What specific phenolic compound isolated from the fruit has shown potent antioxidant capacity in DPPH assays?
Answer
methyl-4-O-galloylchrologenate
The fruit extract contains a wide array of antioxidant polyphenols, including tannins, flavonoids, and phenolic acids like gallic acid and quercetin. To pinpoint a highly specific compound demonstrating measurable potency, laboratory testing has focused on individual isolates. The text explicitly mentions that methyl-4-O-galloylchrologenate, a specific phenolic compound derived from the fruit, demonstrated a potent antioxidant capacity when evaluated using the DPPH assay, which is a standard method for measuring free radical scavenging activity.
