چکیده
Opuntia ficus-indica belongs to the Cactaceae family and is widespread in semi-arid and arid regions. Cactus pears are known for their health promoting properties which are due to a variety of bioactive molecules. This study aims to identify and quantify phenolic acids, flavonoids and betanin from spineless Opuntia ficus-indica fruits. Fresh mature samples were crushed, and extracted with 50% aqueous ethanol. The identification process was carried out using a Shimadzu high performance liquid chromagraph equipped with a quadrupole mass spectrum. Quantification was made using calibration curves of analytical standards. 9 phenolic acids, 1 flavan-3-ol, 2 flavanones, 3 flavonols, 6 flavones and 2 betacyanins were identified. Important levels of betanin, quinic acid, cirsiliol, acacetin, transcinnamic acid, rutin and naringin were calculated. Our results indicated that Opuntia ficus-indica fruits are an important dietary source of phenolic compounds and betalains with high antioxidant capacity.

Juices of edible fruits from Opuntia ficus-indica (L.) Miller, commonly named prickly pears or Indian figs, were analysed for amino acids using an automated amino acid analyser run in the high-resolution physiological mode. Emphasis was put on the detection of free taurine (Tau), but Tau could be detected neither in different cultivars of prickly pears from Italy, South Africa and the Near East...
