Butterfly pea flowers have a beautiful blue colour and are frequently used as colourants in organic skincare. We even used them as an example in one of our natural gel scrubs! Butterfly pea flowers contain anthocyanins, as well as p-coumaric acid and ferulic acid. Apart from anthocyanins, C. ternatea petals contain a lot of flavonoid compounds such as p-coumaric acid and ferulic acid. The anthocyanins of blue butterfly pea petals are derived from an anthocyanidin form called delphinidin.
