Abstract

The aim of this work was to quantify the total phenolic (TPC) and flavonoid contents (TFC) of Cassia tora and laptadeniahastata vegetables consumed in Kano state, Nigeria. Presence of TPC in the leaves of cassia tora and Laptadiniahastata from different sampling areas are as follows: Bebeji sample had 4.41±0.02 mg/g gallic acid equivalent (GAE) and 15.69 ±0.01mg/g GAE, Chalawa sample had 3.41±0.09 mg/g GAE and 6.479±0.036 mg/g GAE, Minjibir sample had 4.72±0.07 mg/g GAE and 7.33±0.03 mg/g GAE, Tudun Wada sample had 5.16±0.09 mg/g GAE and 2.583±0.036mg/g GAE, Garun Malam sample had 5.39±0.03 mg/g GAE and 5.33±0.07 mg/g GAE,Kura sample had 4.5±.01 mg/g GAE and 7.542±0.072 mg/g GAE),Tiga sample had 5.62±0.01mg/g GAE and 14.00±0.132 mg/g GAE respectively whereas, TFC are :Bebeji sample had 17.68±0.01mg/g rutin equivalent (RE) and 6.725±0.06 mg/g RE, Chalawa sample had 10.35±0.04 mg/g RE and 6.392±0.034 mg/g RE ,Minjibir sample had 11.23±0.09 mg/g RE and 5.42±0.03 mg/g RE, Tudun Wada sample had 9.96±0.07 mg/g RE and 6.35±0.02 mg/g RE, Garun Malam sample 16.82±0.04 mg/g RE and 6.52.0.04 mg/g RE, Kura sample had 14.37±0.07 mg/g RE and 6.56±0.03 mg/g RE), Tiga sample had 22.64±0.09 mg/g RE and 5.88±0.42 mg/g RE respectively. Based on the results of this investigation, it can be concluded that Cassia tora and Laptadeniahastata are rich sources of phenolic compounds which are natural antioxidant of high value.
