摘　　要：目的:研究三七紫、绿茎植株营养器官花色苷和皂苷在不同生长阶段的积累量特征。方法:以一、二和三年生三七紫、绿茎植株为材料,用分光光度法检测其叶、茎和根状茎及其不定根的总花色苷和总皂苷含量。结果:从一年生到三年生,紫茎植株叶、茎和总营养器官(包括叶、茎和根状茎及其不定根)的总花色苷含量,茎总花色苷含量占总营养器官总花色苷含量的百分率,紫、绿茎植株叶和茎总皂苷含量占总营养器官总皂苷含量的百分率,绿茎植株叶总花色苷含量占总营养器官总花色苷含量的百分率均下降;绿茎植株叶和总营养器官总花色苷含量,紫、绿茎植株根状茎及其不定根的总花色苷含量,各营养器官总皂苷含量,根状茎及其不定根总皂苷含量占总营养器官总皂苷含量的百分率,紫茎植株根状茎及其不定根总花色苷含量占总营养器官总花色苷含量的百分率均上升;紫茎植株茎和总营养器官的总花色苷含量,茎、根状茎及其不定根和总营养器官的总皂苷含量的增长速率均一直高于绿茎植株,但叶总皂苷含量的增长速率却一直低于绿茎植株,紫、绿茎植株营养器官总花色苷和总皂苷的含量变化呈不同的相关性。此外,三年生时,紫茎植株各营养器官的总皂苷含量均高于绿茎植株,但叶和根状茎及其不定根的总花色苷含量却低于绿茎植株。结论:三七紫茎植株营养器官的皂苷积累能力强于绿茎植株。Objective： To study the accumulation characteristics of total anthocyanins and saponins in the vegetative organ of Panax notoginseng with purple and green aerial stems at different growth stages. Methods： The contents of the total anthocyanins and saponins of the leaves,aerial stems,rhizomes and the adventitious roots of one-,two-and three-year-old Panax notoginseng with purple and green aerial stems were determined by spectrophotometry. Results： From one-year-old to three-year-old Panax notoginseng,the total anthocyanin contents（ TACs） of the leaves,aerial stems and all vegetative organs and the percentages of the aerial stems TACs to those of all vegetative organs of purple aerial stemmed Panax notoginseng plants,the percentages of the total saponin contents（ TSCs） of the leaves and aerial stems to those of all vegetative organs of the purple and green aerial stemmed plants and the percentages of the leaves TACs to those of vegetative organs of the green aerial stemmed plants all decreased; the TACs of the leaves and all vegetative organs of the green aerial stemmed plants,the TACs of the rhizomes and their adventitious roots,the vegetative organ TSCs and the percentages of the TSCs of the rhizomes and their adventitious roots to those of all vegetative organs of the purple and green aerial stemmed plants,and the percentages of the TACs of the rhizomes and their adventitious roots to those of all vegetative organs of the purple aerial stemmed plants increased,the increasing rates of the TACs of the aerial stems and all vegetative organs and the TSCs of the aerial stems,rhizomes and their adventitious roots and all vegetative organs of the purple aerial stemmed plants were always higher than those of the green aerial stemmed plants,but the increasing rates of the leaves TSCs were lower than those of the green aerial stemmed plants,and the content changes of the vegetative organ TACs and TSCs of the purple and green aerial stemmed plants exhibited different correlations. Additionally,the three-years
