Histological Study and Chemical Composition of Apium graveolens: In Vivo Antimicrobial Activity

The purpose of the current investigation is to evaluate the methanolic extract from Apium graveolens seeds for chemical composition and in vivo antimicrobial activity, supported by a histological study. The chemical profile of the methanolic extract was identified using high-performance liquid chromatography diode array detector analysis. The toxicity and antimicrobial effects of the methanolic extract were examined through in vivo experiments on rats weighing 220 ± 5 g. The histological study was conducted using the rats’ ileum. The methanolic extract (80%) contained sinapic acid (49.9%), ascorbic acid (25.4%), butylated hydroxyanisole acid (6.1%), and quercetin (8.2%), with a yield ratio of 11.74%. The dose of 50 mg/kg of the methanolic extract did not lead to animal lethality or toxicity symptoms. Two days after treatment, the blood cultures of all females treated with the methanolic extract at 50 mg/kg showed sterility (100%). The same result appeared on the fifth day after treatment in all males of the same group. Histopathological examination revealed normal and well-preserved architecture of the ileum in both sexes. The study concludes that the methanolic extract of Apium graveolens possesses significant antimicrobial capacity. KEYWORDS Anatomopathology, celery, chemical compounds, enteric infection, HPLC, rats
