Abstract

Context: Eugenia jambolana Lam. (Myrtaceae) is a medicinal plant used in folk medicine for the treatment of diabetes, inflammation, and pain. Objective: We investigated the antinociceptive effect of kaempferol-7-O-α-l- rhamnopyranoside]- 4'-O-4'-[kaempferol-7-O-α-l-rhamnopyranoside (EJ-01), isolated from the E. jambolana leaves. Materials and methods: EJ-01 (3, 10, and 30mgkg-1, orally) was assessed for peripheral (formalin-nociception and acetic acid-writhing) and central (hot plate and tail flick test) analgesic activity in mice and the in vitro anti-inflammatory activity (25, 50, and 100μgmL-1) in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Results and discussion: EJ-01 (10 and 30mgkg-1) significantly inhibited mean writhing counts (37.74 and 36.83) in acetic acid writhing and paw licking time (55.16 and 45.66s) in the late phase of the formalin test as compared with the respective control (60.66 and 104.33s). EJ-01 did not show analgesic activity in central pain models. Significant reduction in the tumor necrosis factor (TNF)-α (295.48, 51.20, and 49.47pgmL-1) and interleukin (IL)-1β (59.38, 20.08, and 15.46pgmL-1) levels were observed in EJ-01-treated medium (25, 50, and 100μgmL-1) as compared with vehicle-treated control values (788.67 and 161.77pgmL -1), respectively. Significant reduction in total nitrite plus nitrate (NOx) levels (70.80nmol) was observed in the EJ-01-treated medium (100μgmL-1) as compared with the vehicle-treated value (110.41nmol). Conclusion: EJ-01 is a valuable analgesic constituent of E. jambolana leaves and this study supports the pharmacological basis for the use of this plant in traditional medicine for curing inflammatory pain.
