Methanol pulls the most healing compounds from this medicinal shrub's leaves
Medicinal Plants
If you grow Vitex negundo (chaste tree relative) as an ornamental or windbreak, this study confirms the folk remedies your neighbors might swear by have real chemical backing, and shows which kitchen-cabinet solvent (alcohol vs. water) would actually extract the good stuff.
Scientists took leaves from Vitex negundo, a shrub used in traditional medicine for pain, fever, and skin problems, and soaked them in three different liquids: methanol (a type of alcohol), water, and chloroform. The alcohol pulled out the widest variety of plant chemicals, including compounds known for fighting inflammation and germs, while water and chloroform each grabbed a narrower, different set. This tells us that if you want to extract the most medicinal compounds from this plant, alcohol-based methods work best.
Key Findings
Methanolic extract showed the richest phytochemical profile, testing positive for most compounds screened including alkaloids, flavonoids, tannins, and terpenoids
Aqueous (water) extract contained a moderate range of predominantly polar compounds
Chloroform extract had comparatively fewer constituents, mainly non-polar compounds like terpenoids and steroids

Researchers tested three different solvents to pull chemical compounds out of the leaves of Vitex negundo, a plant long used in traditional medicine, and found that methanol extracted the widest range of potentially healing compounds like flavonoids, tannins, and alkaloids.

Vitex negundo, commonly known as the Chinese chaste tree, five-leaved chaste tree, or horseshoe vitex, or nisinda is a large aromatic shrub with quadrangular, densely whitish, tomentose branchlets. It is widely used in folk medicine, particularly in South and Southeast Asia.
