Isoquercitrin (Isoquercitroside) is an effective antioxidant and an eosinophilic inflammation suppressor.
Isoquercitrin occurs widely in plants.10 μM of Isoquercitrin of the seven compounds partially but significantly blunt the negative effect of H2O2 on RGC-5 cells, as the viability of cells in the presence of H2O2 is increased from approximately 63% to 83% and 90% at 10 and 50 μM, respectively. Indeed, 50 μM Isoquercitrin is more effective as a neuroprotectant than the same concentration of EGCG[1].
In animals receiving Isoquercitrin, eosinophil counts are lower in the BALF, blood and lung parenchyma. Neutrophil counts in blood and IL-5 levels in lung homogenate are lower only in Isoquercitrin-treated mice. No alterations in mononuclear cell numbers were observed[2].

Animal experiment: |
Mice[2]BALB/c mice are immunized (ovalbumin/aluminum hydroxide, s.c.), followed by two intranasal ovalbumin challenges. From day 18 to day 22 after the first immunization, the mice receive daily gavages of Isoquercitrin (15 mg/kg) or quercetin (10 mg/kg). Dexamethasone (1 mg/kg, s. c.) is administered as a positive control. Leucocytes are analyzed in bronchoalveolar lavage fluid (BALF), blood and pulmonary parenchyma at 24 h after the last ovalbumin challenge. Interleukin-5 (IL-5) is analyzed in BALF and lung homogenates[2]. |

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
