Efficacy and Material Basis of Shuangjin Sanjie Granules in Treatment on Hyperplasia of Mammary Gland / 中国实验方剂学杂志

ABSTRACT

Objective:The SD rat model of hyperplasia of mammary gland（HMG） and the ultrahigh-performance liquid chromatography and mass spectrometry (UHPLC-LTQ-Orbitrap MS) technology were used to explore the pharmacological material basis of Shuangjin Sanjie granules (SJSJG) for the treatment on HMG.Method:SD rat models of HMG were administered in groups, and the nipple height and the diameter were measured; the levels of estradiol (E2), progesterone (P) and prolactin (PRL) in serum were detected, pathological examination was conducted for the hyperplasia of breast tissue. Histochemical methods were used to detect the expressions of estrogen receptor α (ERα), androgen receptor (AR), progesterone receptor (PR), tumor necrosis factor-α (TNF-α) proteins. Finally, UHPLC-LTQ-Orbitrap MS technology was used to detect the main chemical constituents of SJSJG, and the pharmacodynamic substance basis was analyzed based on the pharmacological effect.Result:The results of animal experiments showed that compared with the normal group, nipple height and diameter of the model group increased remarkably (P<0.01), serum E2 significantly increased (P<0.01). Pathological examination showed abnormal hyperplasia of breast tissue， expressions of ERα, AR, PR and TNF-α increased， compared with the model group, the nipple height and diameter of the SJSJG group decreased remarkably (P<0.01), serum E2 was decreased significantly (P<0.01)， pathological examination showed weakened abnormal hyperplasia of breast tissue, ERα, AR, PR and TNF-α protein expressions were significant decreased (P<0.01). The results of basic material study showed that 85 chemical components were identified from SJSJG, including 16 alkaloids, 7 flavonoids, 15 terpenes, 9 phenolic acid compounds, 3 coumarin compounds, 10 esters and lactone compounds, 7 fatty acids compounds, 4 amino acids compounds, and 14 other types of ingredients， among them, alkaloids and terpenoids chemical drug substances were closely related.Conclusion:SJSJG can effectively improve the condition of breast hyperplasia, and its medicinal substance basis may include saikosaponin A, Saikosaponin D, verticinone, peimine.
