To investigate the scientific connotation of harvest period for Prunella vulgaris L. (P vulgaris, known as Prunellae Spica), the triterpenoids and phenols of Prunellae Spica in developmental stages were quantified by high performance liquid chromatography, and the antiinflammatory and anti-breast cancer properties of which were investigated. Furthermore, Grey correlation and Pearson correlation analysis were used to screen the anti-inflammatory and anti-breast cancer-related effective ingredients, and a multidimensional network of "ingredient-target-pathway" through network pharmacology was constructed. The results showed that the harvest time of Prunellae Spica was closely related to its chemical composition and pharmacological activity. Phenols, such as salvianic acid A, caffeic acid, and salviaflaside, mainly accumulated in late development, while rosmarinic acid showed the opposite. Triterpenes, such as oleanolic acid and ursolic acid, mainly accumulated in early development, while betulinic acid accumulated during ripening. The anti-breast cancer activity of Prunellae Spica in early development was stronger than that in the later, but the anti-inflammatory activity in late development was stronger than that in the early stage. Significantly associated with anti-inflammatory activity in Prunellae Spica was salviaflaside, which may regulate TNF and NOD-like receptor signaling pathways by acting on targets such as CASP7, CASP8, CASP3, NOD2, and CASP1. Significantly associated with anti-breast cancer activity were oleanolic acid and ursolic acid, which may regulate Ovarian steroidogenesis and Prolactin signaling pathways on targets such as PTGS2, CYP19A1, ESR2, CYP17A1, and MAPK3. These results suggest that P vulgaris could be harvested before ripening for its antibreast cancer use, and after ripening for its anti-inflammatory use. [ABSTRACT FROM AUTHOR] |
