Abstract

Tiliacora triandra (TT), native to Southeast Asia, has been widely used as folk medicine and in cuisines in many areas. Although little scientific evidence supports the health benefits of TT leaves, the juice extracted from TT leaves has become popular for consumers among all socioeconomic classes. Thus, this study aims to evaluate the phytochemical profile and anti-inflammatory properties of juice extracted from TT leaves. The result revealed that, the highest total phenolic contents (199.92 mg GAE/g), total flavonoid contents (29.76 mg RUE/g), and extraction yield (61.2%) of the lyophilized TT leaves juice powder were found in the solvent mixture of ethanol, water, and acetone extracts. The highest DPPH radical scavenging value (90.95%) of the lyophilized TT leaves juice powder was found in hot water extract. By HPLC analysis, total phenolic compounds of the lyophilized TT leaves juice powder was 3,938.1 mg/kg. Tannic acid, gallic acid, and rutin are the major phenolic compound and the juice is a rich source of chlorophyll compound (3,551.6 mg/kg). The lyophilized TT leaves juice down-regulated the induction of inflammatory iNOS and COX-2 proteins in LPS-stimulated macrophages. The results suggest that intake of TT leaves juice, providing various phenolic and chlorophyll compounds, has great potential for reducing the inflammatory process.
