蘑菇的明亮的橙红色是由于benzotropolone色素aurantricholone（1）。所述化合物至少部分以钙盐形式存在。次要色素为黄色2 H-呋喃并[3，2-B]苯并吡喃-2-酮衍生物橙内酯A（7 a）和B（7 B），其显示出强绿色荧光。通过全合成确定了它们的结构。
The bright orange-red color of the toadstool Tricholoma aurantium is due to the benzotropolone pigment aurantricholone (1). The compound is at least partially present as the calcium salt. Minor pigments are the yellow 2H-furo[3,2-b]benzopyran-2-one derivatives aurantricholides A (7a) and B (7b), which exhibit strong green fluorescences. Their structures have been established by total syntheses.
