Influence of growth stage on the chemical composition, antimicrobial, and antioxidant potential of <i>Cymbopogon martinii</i> (Roxb.) Wats. essential oil.

ABSTRACT:

Introduction

Cymbopogon martinii (Roxb.) Wats. essential oil (CMEO) exhibits significant variation in composition and bioactivity across different growth stages. Understanding these changes is crucial for optimizing its therapeutic and industrial applications.

Methods

CMEO was extracted at the vegetative, reproductive, and post-reproductive stages using hydro-distillation. Chemical composition was analyzed by GC-MS. Antimicrobial activity was assessed using disc diffusion and direct contact assays, while antioxidant potential was evaluated through DPPH, ABTS, and β-carotene bleaching assays. Correlation analysis was performed to link major bioactive compounds with biological activities.

Results

A total of 59 compounds were identified, with the reproductive stag
