Fig 6. Total phenolic, flavonol and flavonoid contents of 10 mg/ml solutions of MCP, MCF and charantin.

(A) phenolic content was determined using the Folin-Ciocalteau method calibrated using gallic acid standards with the results expressed as mg/g of gallic acid equivalents, (B) flavonol content was determined using the AlCl₃ method where the method was calibrated using rutin and results expressed as mg of rutin per g of extract and (C) flavonoid contents of the ethanolic MCP, MCF and charantin extracts determined by a colorimetric method calibrated using rutin and the results expressed as mg of rutin per g of extract. The results are presented as mean ± SD (n = 3). *: p < 0.05, **: p < 0.01.
