Identification and determination of organic acids in some selected medicinal plants grown in Sudan.

The aim of this study is to determine acetic acid, ascorbic citric oxalic acid and tartaric in Sudanese medicinal plants (Adansonia digitata fruit pulp, Hibiscus sabdriffa calyx, Hyphaene thebaica pulp Tamarindus indica pulp) by RP-HPLC-UV method. method used based on using an ultrasonic bath for extracting organic acids. investigation showed that concentrations (1.65 mg/g ±0.099), (56.00 ±0.22), (1.35 ±0.039). highest values Adansonia compared other study. higher concentration (23.75 ± 0.0.36) compare plants, Hypheane lower (0.02 ±0.242). These are recommended as a promising source the above mentioned acids; could contribute considerably towards meeting human nutritional requirements normal growth protection against several diseases.
