Despite widespread use of herbal remedies for treating arthritis and osteosarcoma, many plants are still not pharmacologically evaluated for their efficacy. Contrary to many non-steroidal, immunosuppressants, antibiotics, and antineoplastic drugs that have adverse effects, phytotherapeutic compounds have promising benefits with fewer complications. In this study the unexplored Northeastern India indigenous plant Trevesia palmata (Roxb. ex Lindl.) Vis. used in traditional medicine to cure bone fractures is chosen for studying anti-proliferative and anti-rheumatic properties.This study designed to explore the polyphenolic composition, antioxidant, anti-inflammatory and anti-arthritic potential of T. palmata leaf extracts. Further, the cellular activity was studied using MG 63 osteoblast cell lines and pharmacologically evaluated using Complete Freund's Adjuvant (CFA) induced arthritic rat model.In vitro free radical scavenging activity, anti-inflammatory and anti-arthritic activities of extracts were analyzed using standardized methods. The polyphenolic profiling and apoptosis inducing ability of T. palmata ethyl acetate (TPEA) extract on MG 63 osteoblast cell lines were analyzed. The in vivo pharmacological studies were carried out with low dose 250 mg/kg and high dose of 500 mg/kg of T. palmata. The biochemical and haematological parameters and in vivo antioxidant activity were evaluated for the control and treated groups. Radiological and histological study were done to understand the impact and penetration of inflammatory arthritis from tissues to joint bones.TPEA showed highest free radical scavenging activity (DPPH - 4.72 ICThe potential treatment of polyphenolic compounds in the T. palmata extract on osteosarcoma and arthritis was demonstrated from this study. Thus, cellular inflammatory infiltrates are significantly reduced in bone and joint tissues as well. |
