Limonene: A Potent Monoterpene with Diverse Applications and Benefits

Monoterpenes are a class of organic compounds that consist of two isoprene units and are found in various essential oils derived from plants. They play a vital role in the plant world, contributing to their aroma, flavor, and defense mechanisms. In recent years, monoterpenes have gained popularity due to their potential therapeutic benefits and uses in various industries. One such monoterpene that has garnered significant attention is Limonene.

Limonene: A Brief Overview

Limonene is a naturally occurring monoterpene that is primarily found in the rinds of citrus fruits such as oranges, lemons, and limes. It is responsible for the distinct citrus aroma and is widely used in the food, beverage, and cosmetic industries as a flavoring agent and fragrance. Beyond its pleasant scent, limonene has been the subject of numerous studies for its potential health benefits and therapeutic properties.
