Estimation of total phenolic, total flavonoid content and evaluation of anti-inflammatory and antioxidant activity of Ixora coccinea Linn. stems
Abstract: Ixora coccinea Linn.
(Rubiaceae) has mentioned in Ayurveda as Paranti and traditionally stems used
in inflammatory diseases like sprains, eczema, contusions and boils. Present study deals with evaluation of
anti-inflammatory and antioxidant activity of extracts of I.coccinea stem.
Anti-inflammatory activity was studied in vivo by carrageenan-induced paw edema
in rat and in vitro by human red blood cell membrane stabilization method.
Total tannin and flavonoid content of extracts was determined by using the
Folin- Ciocalteu method and aluminum chloride method, respectively. Antioxidant
activity was evaluated by in vitro assay involving nitric oxide scavenging,
hydrogen peroxide scavenging, 2,2-
diphenylpicrylhydrazyl (DPPH) radical scavenging, and ion chelating
activity. Chloroform extract showed significant reduction in carrageenan
induced rat paw edema (p<0.05) and protection of HRBC in hypotonic solution.
Methanol extract contain more total tannin and flavonoid content as compared
with petroleum ether and chloroform extract. All extracts showed concentration
dependant free radical scavenging activity. Methanol extract and chloroform
extract have shown better antioxidant activity and due to this antioxidant
nature might be responsible for its anti-inflammatory activity. These activity
supports to use of I.coccinea extract in traditional used in treatment of
various inflammatory disaeses.
