Chemical Composition, Analgesic and Anti-Inflammatory Activity of Pelargonium peltatum Essential Oils from Eastern Cape, South Africa

species are native to South Africa, and they have a long history in medicinal use. This study aimed to extract essential oils from different parts of , determine the chemical composition of the essential oils, and assess the essential oils' biological potential as analgesic and anti-inflammatory agents. The essential oils were obtained by hydro-distilling different parts of , and the essential profile was determined by GC-FID and GC-MS. The analgesic activity of the essential oil was determined by using a tail immersion in hot water method in rats, whereas the anti-inflammatory activity of the essential oils was assessed according to right hind paw oedema induced by egg albumin; the three doses selected for each experiment were 100, 200, and 400 mg/kg. According to the GC-FID and GC-MS analysis, camphene (3.6-33.4%), α-terpineol (4.8-19.1%), α-thujone (1.5-15.6%), piperitone (0.9-12.2%), linalool (1.6-11.7%), myrcene (5.2-10.7%), germacrene D (3.7-10.4%), β-caryophyllene (1.2-9.5%), β-cadinene (3.4-6.7%), and β-bourbonene (4.2-6.2%) were some of the major compounds identified in the oil. essential oils demonstrated analgesic activity by increasing pain latency in hot water; furthermore, in an inflammation test, the essential oil reduced the egg-albumin-induced paw oedema in both the first and second phases. Therefore, the current findings suggest that essential oils have analgesic and anti-inflammatory properties.
