The presence of betacyanin pigments and their isoforms has been detected in the fruit of Hylocereus polyrhizus, a vine cactus native to South America. Along with the known betanin and phyllocactin (6'-O-malonylbetanin), a new betacyanin was structurally elucidated as betanidin 5-O-[6'-O-(3"-hydroxy-3"-methyl-glutaryl)-beta-D-glucopyranoside] (proposed trivial name hylocerenin) by means of electrospray MS/MS, HPLC, and NMR techniques.
在原产于南美洲的藤本仙人掌多花量天尺的果实中，已检测到甜菜色素及其异构体的存在。除了已知的甜菜红素和仙人掌果红素（6'-O-丙二酰基甜菜红素）外，通过电喷雾串联质谱、高效液相色谱和核磁共振技术，一种新的甜菜色素在结构上被鉴定为甜菜配基5-O-[6'-O-(3''-羟基-3''-甲基-戊二酰基)-β-D-吡喃葡萄糖苷]（暂定名称为量天尺红素）。
