应用
丹酚酸 B 也已被用于处理原代神经元细胞，以测试其对细胞活力的影响。
丹酚酸B(Sal B)已用于通过硫黄素T(ThT)荧光法测定丹酚酸B对α-突触核蛋白聚集动力学的抑制作用。它还用作参考化合物，用于通过指纹图谱分析确认myelophil（黄芪丹参混合物）的可重复性。
生化/生理作用
丹酚酸 B 是一种具有细胞保护作用的抗氧化剂和自由基清除剂，广泛用于治疗缺血性心脏病和阿尔茨海默病。已提出了几种作用机制，包括 EGFR、PDGF 和 MMP-9 抑制以及 TGF-β1/Smads 和 NF-κB 信号通路抑制。丹酚酸 B 作为活性氧的清除剂，减少白细胞对内皮细胞的粘附，抑制基质金属蛋白酶和炎症。它具有心脏保护作用，因为它能减少受损心脏组织中的脂质过氧化，并减少乳酸脱氢酶的漏出。

The degradation of lithospermic acid B (LAB) was investigated as a function of buffer concentration, pH and temperature. Stability tests were performed using a stability-indicating high-performance liquid chromatography (HPLC) with UV-vis detection. The degradation followed pseudo-first-order kinetics under all experimental
