Abstract
Betalains are characteristic vacuolar pigments that entirely replace anthocyanin in most plants in the Centrospermae family. They can be divided into two structural groups, yellow-orange betaxanthins and red-purple betacyanins, both of which have betalamic acid as their basic structure. However, most of the betalain-containing crops have certain drawbacks which affect the global use as a natural food colourant. The Portulacaceae members belonging to the order Caryophyllales are characterized by the accumulation of Betalains in flowers, fruits and occasionally in vegetative tissues. Talinum triangulare (Family: Portulacaceae) popularly known as waterleaf naturally produces the nitrogen-containing plant pigment in flowers and stems. Hence, the aim of the present study was to produce and estimate Betalains by adapting in vitro tissue culture strategies from the medicinal herb T. triangulare . The betacyanin and betaxanthin patterns were detected, analyzed and characterized by applying high performance liquid chromatography photo-diode array detection (HPLC-PDA) coupled with positive ion electro-spray mass spectrometry. In vitro assays including antimicrobial efficacy, antioxidant activity and cytotoxicity were investigated to analyse the efficacy of the Betalains samples. Furthermore, the storage, stability and viability of the pigment were determined for its applications in food products. Altogether, the findings of our study may open new opportunities for screening of betalainic plants such as T. triangulare as promising future sources for natural food colours
