In this study, two extracts from Fatsia japonica-Fatsiphloginum™ (extract of triterpene glycosides containing 45-50 % of fatsiosides (FS)) and purified triterpene-rich extract of saponins with code name PS-551 (PS) were administered in combination with methotrexate (MTX) and in monotherapy to rats suffering adjuvant arthritis (AA). The anti-inflammatory activities of extracts were evaluated as monotherapies in comparison with untreated AA. PS administered in higher dose showed on day 28 effective decrease of hind paw volume (HPV), decreased activity of gamma-glutamyl transferase (GGT) in joints, and also interleukin-17A was decreased significantly on day 14. The higher dose of PS was more effective than both doses of FS. Further, we evaluated the higher doses of PS and FS in combination with MTX. PS improved the effect of MTX in combination more effective than FS (HPV, body weight and activity of GGT in joint). However, FS was more effective in reducing the level of IL-17A on day 14 and activity of GGT in spleen than PS. In conclusion, our study showed that generally FS has higher anti-arthritic activity comparing to PS. Thus, the novel combination of Fatsiphloginum™ and methotrexate could be interesting for future clinical studies in patients suffering auto-immune diseases.
:"Fatsiflogin" is an original, nonsteroidal para-medical preparation from the leaves of Fatsia japonica with anti-rheumatic, anti-inflammatory and analgesic activities. Fatsioside D (tetraosid of hederagenin) as one of the major compound of "Fatsiflogin", was selected as a chemical markerfor the quantitative validation. The objective of this study is to develop a simple and reliable HPLC method for the determination of Fatsiosid D for quality control studies of "Fatsiflogin". FatsiosideD was purified by preparative HPLC and the structure of the compound was determined by NMR. HPLC separation was performed on an intertsil prep-ODS C18 column, with a solvent system water-acetonitrile. The UV detection is performed at 205 nm. The proposed HPLC method is linear in the range studied (r 2 > 0.999) for all the analytes. The method is precise with intra-and inter-day variations of less than 3.34%. The mean recoveries of the analytes range from 99.68 to 100.29%. The method is successfully applied to the quantification of Fatsioside D. The results indicated that developed HPLC method could be used for the quality control of "Fatsiflogin".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
