(Natural News) Tectaria coadunate is a species of fern that has attracted scientific interest in recent years. Also known by its local name, kali niyuro, it is a commonly consumed, nutritious vegetable in Nepal.

Quite a few studies have been conducted on this edible medicinal plant, owing to its wide ethnomedicinal usage. Investigations into its biological properties have revealed that T. coadunate has strong antioxidant, antibacterial and anti-cancer properties.

In a recent study, researchers from Nepal decided to look into the phytochemical composition and nutrient content of T. coadunate. They also compared the biological activities of T. coadunate leaf and rhizome extracts.

The researchers reported their findings in an article published in the International Journal of Herbal Medicine.

T. coadunate has antioxidant, antimicrobial and anti-diabetic properties

For their experiment, the researchers first obtained extracts from the leaves and rhizomes of T. coadunate using methanol and hexane as solvents. Phytochemical analysis revealed that they contained large amounts of alkaloids, polyphenols and tannins.

Some of the notable compounds present in T. coadunate include decanediol, dodecanoic acid (lauric acid), methyl stearate and palmitic acid.

The total phenolic and flavonoid contents of the methanol extract of T. coadunate rhizomes were 186.61 mg (gallic acid equivalent, GAE)/g and 143.72 mg (quercetin equivalent, QE)/g, respectively.

The researchers also found that fresh T. coadunate leaves contained:
