Antimicrobial Activity of Tea and Agarwood Leaf Extracts Against Multidrug‐Resistant Microbes

Emerging multidrug‐resistant (MDR) strains are the main challenges to the progression of new drug discovery. To diminish infectious disease–causing pathogens, new antibiotics are required while the drying pipeline of potent antibiotics is adding to the severity. Plant secondary metabolites or phytochemicals including alkaloids, phenols, flavonoids, and terpenes have successfully demonstrated their inhibitory potential against the drug‐resistant pathogens. In quest of potential phytochemicals, we selected tea ( Camellia sinensis ) and agarwood ( Aquilaria malaccensis ) leaves for antimicrobial activity. Fresh tea leaves were collected in three varieties, namely, BT‐6, BT‐7, and BT‐8, including green tea (nonfermented tea), black tea (fully fermented tea), and agarwood leaves collected from Sylhet region of Bangladesh. This study is aimed at analyzing the phytochemical constituency…
