Phytochemical characteristics from Phaleria macrocarpa and its inhibitory activity on the peritoneal damage of endometriosis

Abstract

Background: Endometriois represents a gynecological disease that still becomes an issue in community. Phaleria macrocarpa is a plant native to Indonesia that contains an antioxidant substance, which may serve as apoptotic modulator and useful for angiogenesis. Objective: This study aims to evaluate the effects of flavonoid isolates from P. macrocarpa (PM) on the development of granulomas, apoptosis, proliferation, and angiogenesis of the disease. Material and methods: Total thirty mice (Mus musculus) were categorized into six groups, including the normal group (without any treatment), EMT (endometriosis) group, and EMT group treated with PM flavonoid isolates. Identification of the active compounds of P. macrocarpa was done using LC-HRMS. Measurement of granuloma scores and vascular density was done histologically. Apoptosis and proliferation analysis was performed by immunohistochemical techniques. Results: There was an increase in granulomas, proliferation, and apoptosis in the peritoneal tissues of the endometriosis model. This change can be normalized by extract of P. macrocarpa. Conclusion: We concluded that the flavonoid isolates from P. macrocarpa can suppress the growth of endometriosis lesions through normalization of proliferation and apoptosis. Thus, the P. macrocarpa flavonoid can be used as an alternative to inhibit the development of endometriosis.
