生化/生理作用
Sparstolonin B（SsnB）是一种从黑三棱和荆三棱中分离得到的异香豆素，是一种有效的TLR2和TLR4拮抗剂，具有抗炎和抗病毒（抗HIV）特性。Sparstolonin B在3T3- L1脂肪细胞中可抑制LPS诱导的炎症，并降低高脂饮食喂养的大鼠体重。Sparstolonin B可减轻小鼠模型中非酒精性脂肪性肝炎（NASH）的炎症。
Sparstolonin B（SsnB）是一种多酚。它具有类似于氧杂蒽酮和异香豆素的结构特征。 SsnB对小鼠和人类巨噬细胞具有抗炎效果。 SsnB可通过阻断细胞外信号调节蛋白激酶（ERK1/2）和c-jun N端激酶（JNK）信号通路而显著降低缺氧-再氧合诱导的心肌炎。因此，SsnB可作为治疗心肌缺血再灌注（MIR）损伤的一种有效疗法。
