Research articles related to Pandanus odoratissimus:
Anti – inflammatory action: This study examined the anti – inflammatory activity of Pandanus odoratissimus. The anti – inflammatory activity was estimated by carrageenan – induced acute and formalin – induced chronic paw edema models in rats. The methanolic extract of Pandanus odoratissimus was given in the doses of 25, 50 and100 mg kg – 1. The plant extract at the dose of 100 mg kg – 1 showed significant anti – inflammatory activity peaked at 3 h where, it caused inhibition for the increase in carrageenan – induced acute (68%) and for the increase in formalin – induced chronic (64.2%) paw edema models in rats. The standard drug was used as diclofenac sodium. As a result methanolic extract of Pandanus odoratissimus was shown to have an anti – inflammatory activity.
In this study, several neuropharmacological effects of methanolic leaf extract of Pandanus odoratissimus (PO) (family; Pandanaceae) were studied in albino mice using various experimental models. The methanolic leaf extract (50,100 and 200 mg/kg i. p.) produced a reduction in spontaneous motor activity, motor coordination and prolonged Pentobarbital sodium sleeping time. Preliminary qualitative chemical studies indicated the presence of steroids, saponins, terpinoids, glycosides, tannins, flavonoids and phenolics in the extract. These observations suggest that the leaf of Pandanus odoratissimus contains some active principles which possess potential CNS – depressant action.
Anti – cancer study: The objective of the present study was to explore the dose – dependent in vitro anticancer effects of the extracts of Pandanus odoratissimus. The dried parts of roots and leaves were extracted with methanol (MEPO) and water (AEPO). The extracts were then subjected to in vitro cytotoxic and antimitotic screening by brine shrimp lethality assay and onion root tip method, respectively. AEPO showed significant cytotoxic and antimitotic activities. It showed 100% lethality of brine shrimps at 80 ?g/ml and an LC50 of 33.33 ?g/ml, which was eightfold higher than that of synthetic standard podophyllotoxin (4.16 ?g/ml). The plant has the potential to be used in anticancer therapy, and this study scientifically validated the folklore use of this plant.
Hepato – protective action: The pupose of the study was to investigate the hepato – protective activity of methanol extracts of peduncles, flowers and spathes of Pandanus odoratissimus inflorescence in acetaminophen – induced hepatotoxicity in guinea pigs. The methanol extract of the peduncle alleviated the liver damage induced by APAP as evident by the improved histopathology picture similar to that of silymarin which presented with only mild hydropic and fatty changes. The extract also reduced the liver enzymes – AST, ALT and ALP – by 42, 50 and 59 %, respectively (p < 0.05), but the reduction (32 %) in total bilirubin was not significant 32 %. On the other hand, the flower extract only lowered AST and ALP by 31 and 48 % (p < 0.05), respectively, while the reduction in ALT and total bilirubin by 33 and 18 % respectively, was not significant.
