染料紫檀，紫檀木的一种。原产地非洲，因其颜色较深，为紫红色或褐色，市场上几种染料紫檀，国内俗称非洲血檀，也被叫做“血檀”。 典型特征是木纹较清晰，剖面上紫色中带有大面积血色斑条，许多时候如手抹状，呈无规则分布。这种紫檀在刚刚剖开木料之时，血状分布及色泽赫然显现，观者无不唏嘘。 木材不管新切面还是久置都没有显著的气味，水浸液荧光从不明显至明显的现象均存在，木材密度在0.75-1.30克/立方厘米不等。木材宏观特征是散孔材，管孔弦向直径从250微米至40微米变化，轴向薄壁组织离管细带状和聚翼状，局部星散聚合或环管束状。微观下观察，木射线均为同形单列叠生，少数可见2列和对列出现，是紫檀属木材的典型特征。 The Pterocarpus tinctorius is a kind of rosewood.
