In a study published in the Journal of Essential Oil Research, researchers from Vietnam Academy of Science and Technology and Phu Yen University evaluated the bioactivity and physicochemical characteristics of the essential oils obtained from the leaves and flowers of calamondin. They found that the oils have antioxidant, anti-microbial, and anti-fungal properties.
The essential oil obtained from calamondin flower is dominated by monoterpene hydrocarbons including limonene. Meanwhile, the main compounds found in the leaf essential oil are sesquiterpenes and elemol.
The researchers also evaluated the antioxidant activity of both calamondin flower and leaf essential oils using DPPH and ABTS radical scavenging methods. They found that the antioxidant activities of both are higher than that of vitamin C.
The researchers also tested calamondin flower and leaf essential oils against microbial and fungal strains. The results showed that the leaf essential oil exhibited inhibitory effects against six microbial strains, while the flower essential oil inhibited only one fungus strain, which was Aspergillus niger.
Taken together, the results of the study suggested that both calamondin flower and leaf essential oils have antioxidant, antimicrobial, and antifungal properties. (Related: Calamansi fruit from the Philippines found to be a powerful anticancer food.)
The calamondin plant is an evergreen shrub that bears small, juicy lime-like fruits, dark green foliage, and white flowers. Calamondin fruit is extremely sour in taste. You can use it to make juice or use it as a condiment. The plant grows up to 25 feet tall. Like most citrus trees, calamondin grows readily from seed. You can also find calamondin saplings or cuttings at a plant nursery and plant it in pots or your yard. Calamondin grows in a warm tropical and subtropical climate. It thrives outdoors in the U.S. Department of Agriculture plant hardiness zones 9 through 11. Here is a guide on how to grow your own calamondin using calamondin saplings or cuttings:
