According to a study published by "Pakistan journal of pharmaceuticaal sciences", the ethanolic extracts of Eucalyptus tereticornis leaves demonstrate antibacterial activity against Gram-positive and Gram-negative bacteria. To obtain these extracts, 20 g of leaf powder was mixed with 200ml of ethanol and centrifuged at 4000 rpm for 10 min. The antibacterial effectiveness was measured using 100μl of test microorganism, with zones of inhibition for S. aureus PCSIR-83 and E. coli PCSIR-102 ranging from 0-28mm, and B. subtilis PCSIR-05 ranging from 15-26mm. A combination involving 20mg/μl of E. tereticornis was found to be most effective at pH 9.0 and a temperature of 35°C. These results indicate that Gram-positive bacteria showed more sensitivity than Gram-negative bacteria.
The primary pharmacological activities of this plant are shown in the list below.
- antibacterial
- antimicrobial

What medicinal compounds this plant contains?
This plant contains the medicinal compounds ursolic acid, eucalyptol, alpha-pinene, camphene, and limonene. Ursolic acid is particularly noted for its significant anti-inflammatory and potential anti-tumor properties. The essential oil component eucalyptol provides potent antimicrobial and decongestant effects when inhaled or applied. Additional terpenes like alpha-pinene and camphene contribute to the plant's overall antiseptic and soothing characteristics. Limonene further enhances these biological activities by offering antioxidant support to the body.
As discussed in a study, the leaves of Eucalyptus tereticornis were chemically investigated and resulted in the isolation of ursolic acid (UA) as a major constituent. This anti-filarial agent was found to be lethal to microfilariae with an LC100 of 50 and an IC50 of 8.84 µM, while female adult worms showed an LC100 of 100 and an IC50 of 35.36 µM. UA exerted 86% inhibition in the MTT reduction potential of adult parasites and achieved a LibDock score of -8.6. In an in vivo model, the compound showed 54% macrofilariciidal activity and 56% female worm sterility.
The primary medicinal compounds of this plant are shown in the list below.

What health conditions is this plant used for?
This plant is used for managing alcohol-induced hepatocyte toxicity, ethanol toxicity, ethanol-induced toxicity, hyperglycemia, and inflammation. Its bioactive compounds demonstrate significant protective effects against liver damage caused by excessive alcohol consumption. Research indicates that the extracts can effectively mitigate the cellular stress associated with ethanol-induced toxicity. Furthermore, the plant possesses properties that help regulate blood sugar levels to combat hyperglycemia. It also functions as a potent agent to reduce systemic inflammation in various biological models.
According to a study published by "Phytotherapy research : PTR", ursolic acid isolated from the leaves of the Eucalyptus hybrid E. tereticornis protects against ethanol toxicity in isolated rat hepatocytes. Ethanol alone resulted in a 48%-54% decrease in hepatocyte viability and a 42%-54% reduction in the biochemical parameters of the cells. The simultaneous presence of ursolic acid in the cell suspension preserved viability and reversed the ethanol-induced loss in the levels of all studied marker enzymes, specifically AST, ALT and AP. Ursolic acid demonstrated a concentration dependent preventive effect ranging from 12%-76% on alcohol-induced hepatocyte toxicity when used at concentrations of 1-100 microg/mL.
The main health conditions this plant is used for are shown in the list below.
