- Peppermint has anti-microbial and antifungal properties
- A new study explores the chemical composition of peppermint grown in African region
- The chemical composition of essential oil varies due to climate, maturity, etc. of plant
- Research finds the similarity of components in oil derived from Turkish and African peppermints.
African peppermint is a type of peppermint that has been cultivated in the African regions. The scientific name of Peppermint is ‘MenthaPiperita,’ and it has been considered as a cross hybrid of watermint and spearmint.
The peppermint is cultivated widely in Mediterranean region and can be used as herbal medicine. The essential oil processed from peppermint have incredible features.
A new study, conducted by a team of professionals from Sidi Mohamed Ben Abdellah University, Fez, Morocco, North Africa, analyzed the features and molecular structure of essential oil from African grown Peppermint.
Usually, the molecular composition of essential oil taken from Peppermint varies according to geography, climate, plant’s age and maturity, species, etc. The recent study evaluated the composition of essential oil from the peppermint plants nurtured and cultivated in various regions of Africa.
As a part of the research, fresh aerials of Peppermint were subjected to Hydro-distillation, process to derive essential oil from the plant. After the process, the essential oil was kept at 4 degree Celsius and in the dark in order to avoid any chemical changes in the oil.
The effect of essential oil on seven isolates of different bacteria and one fungus were tested for the study. The major constituents of the essential oil were Menthol, Menthofuran, Menthyl Acetate, Menthone, and Cineole. Two bacteria M. luteus and B. subtilis were too sensitive to the essential oil while the growth of S. aureus and B. cereus bacteria were stopped completely.
The essential oil also exhibited anti-fungal properties barring the fungal growth in higher concentration.
According to the researchers, the chemical composition of essential oil from African Peppermint was similar to that of peppermint from Turkey. Methanol is the major component in both and other studies had proved it.
The study revealed that presence of Oxygenated Monoterpenes was the reason for anti-bacterial and antimicrobial properties of essential oils. It also added that anti-microbial property of essential oil from Peppermint could be due to the synergy between the constituent components.
