What medicinal compounds this plant contains?

This plant contains the medicinal compounds catechin, catechins, epicatechin, epigallocatechin, and tannins. These polyphenolic substances are primarily responsible for the plant's significant antioxidant and anti-inflammatory properties. The presence of various catechins helps in neutralizing free radicals within the body. Specifically, epicatechin and epigallocatechin contribute to cardiovascular health and cellular protection. Additionally, the high concentration of tannins provides astringent qualities that can assist in treating various ailments.

According to a study published by "Journal of agricultural and food chemistry", the medicinal plant Acacia catechu contains predominant catechins including catechin, epicatechin, epicatechin-3-O-gallate, and epigallocatechin-3-O-gallate. Other major secondary products identified in the plant include caffeine, flavanol dimers, and flavonol glycosides. For the four investigated catechins, the method obtained good linearities with r2 > 0.99 for each calibration curve. Validation showed an accuracy ranging from 1.06 to 11.76% for these analytes. The precision, expressed as relative standard deviation, varied between 1.60 and 9.36% for these four substances. This research represents the first quantitative determination of all predominant catechins in the heartwood and leaves of Acacia catechu.
