以原产于中国的牡丹品种牡丹（P. suffruticosa）及其与黄牡丹（P. lutea）、青牡丹（P. delavayi）的种间杂种为材料，通过花色素苷含量的测定，研究了日本牡丹品种的花色素苷含量的变化。在国际照明委员会（CIE）（L*，a*，B*）色坐标上，红蓝范围内分布着紫斑牡丹属植物。红紫色品种的蓝色和红色值均较高，而粉红色或白色品种的值较低。深红色或深紫红色品种的花瓣中含有大量的花色苷，而粉红色或白色品种的花瓣中含有少量的花色苷。因此，花瓣亮度与叶片颜色呈高度负相关，所有深红色或深紫红色的日本品种都含有6种花色苷，即芍药色素3，5-二葡萄糖苷（Pn 3G 5G）、芍药色素3-葡萄糖苷（Pn 3G）、矢车菊色素3，5-二葡萄糖苷（Cy 3G 5G）、矢车菊色素3-葡萄糖苷（Cy 3G）、天竺葵色素3，5-二葡萄糖苷（Pg 3G 5G）和天竺葵素3-葡萄糖苷（Pg 3G）。鲜红色品种缺乏Cy 3G/Cy 3G 5G，但含有大量的Pg 3G/Pg 3G 5G。部分粉红色品种缺少Pn 3G和Pg 3G以及Cy 3G/Cy 3G 5G。和P. suffruticosa var.美国种与法国种之间的杂种P. suffruticosa和P. lutea和P. delavayi缺乏Pg 3G和Pg 3G 5G。缺乏天竺葵素产生了深红色或猩红色的花朵杂交，但在存在的黄色查耳酮，芍药素和矢车菊素在一些品种产生了橙子或栗色的花朵。黄色素遗传自黄球藻（P. lutea）和红球藻（P. delavayi）。
Flowers of the tree peony, Paeonia suffruticosa, and its interspecific hybrids with P. lutea, and P. delavayi, which originated in China and which were introduced by American and French breeders, were assayed for anthocyanins to trace their development.Petal hues of all Japanese cultivars (Paeonia suffruticosa) were distributed within the blue-red scope on Commision Internationale de l'Eclairage (CIE) (L*, a*, b*) color coordinate. Reddish purple cultivars had high values of both blue and red, whereas pink or white cultivars had low values. Dark red or deep red-purple cultivars contained a large amount of anthocyanins in the petals, whereas pink or white cultivars contained a slight amount. Therefore, there was a high negative correlation between petal lightness (Hunter's L value) and petal anthocyanin contents.All dark red or deep red-purple Japanese cultivars contained 6 anthocyanins, peonidin 3,5-diglucoside (Pn3G5G), peonidin 3-glucoside (Pn3G), cyanidin 3,5-diglucoside (Cy3G5G), cyanidin 3-glucoside (Cy3G), pelargonidin 3,5-diglucoside (Pg3G5G) and pelargonidin 3-glucoside (Pg3G). Vivid red cultivars lacked Cy3G/Cy3G5G but contained large amounts of Pg3G/Pg3G5G. Some pink cultivars lacked Pn3G and Pg3G as well as Cy3G/Cy3G5G.Of the 6 anthocyanins present in the Japanese cultivars, the Chinese cvs. of P. suffruticosa and P. suffruticosa var. spontanea generally lack Pg3G, which may account for the absence of the vivid red color.American and French interspecific hybrids between P. suffruticosa and P. lutea and P. delavayi lack Pg3G and Pg3G5G. The lack of pelargonidins gave rise to hybrids with crimson or scarlet flowers; but in the presence of a yellow chalcone, peonidin and cyanidin in some cultivars gave rise to orange or maroon flowers. The yellow pigment is inherited from the P. lutea and P. delavayi.
