The presence of 14 betalain pigments have been detected by their characteristic spectral properties in flower petals of Christmas cactus (Schlumbergera x buckleyi). Along with the known vulgaxanthin I, betalamic acid, betanin and phyllocactin (6'-O-malonylbetanin), the structure of a new phyllocactin-derived betacyanin was elucidated by various spectroscopic techniques and carbohydrate analyses as betanidin 5-O-(2'-O-beta-D-apiofuranosyl-6'-O-malonyl)-beta-D-glucopyranosid e. Among the more complex betacyanins occurring in trace amounts, the presence of a new diacylated betacyanin ¿betanidin 5-O-[(5"-O-E-feruloyl)-2'-O-beta-D- apiofuranosyl-6'-O-malonyl)]-beta-D-glucopyranoside¿ has been ascertained. Furthermore, the accumulation of betalains during flower development and their pattern in different organs of the flower has been examined.
通过圣诞仙人掌（Schlumbergera x buckleyi）花瓣中甜菜色素的特征光谱特性，检测到了14种甜菜色素的存在。除了已知的紫黄质I、甜菜醛酸、甜菜红苷和叶仙人掌苷（6'-O-丙二酰基甜菜红苷）外，还通过各种光谱技术和碳水化合物分析，阐明了一种新的源自叶仙人掌苷的花青素的结构，即甜菜苷5-O-(2'-O-β-D-阿吡喃糖基-6'-O-丙二酰基)-β-D-吡喃葡萄糖苷。在痕量存在的更为复杂的花青素中，已确定存在一种新的二酰化花青素——甜菜苷5-O-[(5"-O-E-阿魏酰基)-2'-O-β-D-阿吡喃糖基-6'-O-丙二酰基)]-β-D-吡喃葡萄糖苷。此外，还研究了甜菜色素在花发育过程中的积累情况及其在花的不同器官中的分布模式。
