– Antimicrobial Activity: Results showed that crude leaf extracts of Eupatorium triplinerve has antibacterial and antifungal properties.
– Antimicrobial Activity: Study of extracts of leaves of Eupatorium ayapana showed the petroleum ether extract to have higher antibacterial and antifungal activity than the methanolic extract.
– Essential Oil / Thymohydroquinone: Study investigated the leaf oil composition. Three essential oil samples showed a high percentage of the aromatic compound thymohydroquinone dimethyl ether.
– Hepatoprotective / Antioxidant: Study of methanol extract of E ayapana leaves in Wistar albino rats showed decrease of the activity of serum enzymes, bilirubin, uric acid and lipid peroxidation. Results suggest that MEEA possess hepatoprotective and antioxidant properties.
– Anthelmintic: Essential oil from the flowers of Eupatorium triplinerve has been shown to possess good efficacy against Ascaris lumbricoides and Taenia solium (Garg, S.C., Nakhare, S., 1993. Studies on the essential oils from the flowers of Eupatorium triplinerve. Indian Perfumer 37, 318-323).
– Anthelmintic / Comparative Study: Eupatorium triplinerve exhibited a dose dependent anthelmintic activity against both Pheritima posthuma and Ascardia galli in vitro models. Alpinia galanga showed no activity against P. posthuma but exhibited potent dose dependent activity against A. galli.
– Anti-Melanogenesis / 7- Methoxycoumarin / Skin Whitening: A methanol extract of leaves of E. triplinerve showed antimelamogenesis activity in a melanin biosynthesis assay. 7-methoxycoumarin was isolated as an active compound. The results validated the traditional use of the plant by the Dayak tribe in East Kalimantan.
– Antinociceptive / Antioxidant / Neurobehavioral Effects: Study evaluated the putative effects of E. triplinerve on the central nervous system. Results showed mild sedative, anxiolytic, and antidepressive effects on the CNS. Antinociceptive effects not related to the opioid system and antioxidant activity were also observed.
– Antioxidant Mediated Antiulcer Effect / Induced Ulcerative Colitis: Study evaluated the effect of a methanolic extract of fractions of E. triplinerve on acetic acid induced ulcerative colitis in male adult mice. Results showed an antiulcer effect against UC at colon specific area through its radical scavenging activity.
– Anticoagulant Effect: Ayapana leaves contain naturally occurring coumarins with its blood thinning and anti-coagulant effect. A patient on blood thinning medications should avoid the concomitant use of ayapana and should consult a physician.
