Heart tonic herbal teas were developed to select herbal teas to enhance cardiovascular health. The herbal teas were separated into 2 formulas: first Pleurotus ostreatus: Pandanus amaryllifolius: Oryza sativa cv. KDML 105 (brown rice): Oryza sativa cv. KDML 105 (leaves): Clitoria ternatea; 1: 1:1:1:1 (w:w:w:w;w) and second Ganoderma lucidum: Caesalpinia sappan: Aegle marmelos: Chrysanthemum indicum: Carthamus tinctorius; 1:1:1:1:1 (w:w:w:w;w) which were extracted with aqueous infusion. Phytochemical screening was used to examined flavonoid and phenolic acid compounds using High-Performance Liquid Chromatography (HPLC) and the total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were determined. The antioxidant activity was determined using 2 2-diphenyl-1-picrylhydrazy (DPPH) radical scavenging and Ferric reducing antioxidant Power (FRAP) assay. The results showed that the second formula contained significantly higher TPC TFC flavonoid compounds and phenolic compounds than the first formula. Antioxidant activities with DPPH and FRAP assay of the second formula (16.88 0.25 mgTE/g and 62.97 2.45 mM Fe� E/g respectively) was significantly higher than the first formula (5.41 0.03 mgTE/g and 13.57 1.10 mM Fe� E/g respectively). These findings indicated that the second formula of the heart tonic herbal tea has an inhibitory free radical effect and has the potential to improve cardiovascular health following its consumption.

Abstract

Heart tonic herbal teas were developed to select herbal teas to enhance cardiovascular health. The herbal teas were separated into 2 formulas: first Pleurotus ostreatus: Pandanus amaryllifolius: Oryza sativa cv. KDML 105 (brown rice): Oryza sativa cv. KDML 105 (leaves): Clitoria ternatea; 1: 1:1:1:1 (w:w:w:w;w) and second Ganoderma lucidum: Caesalpinia sappan: Aegle marmelos: Chrysanthemum indicum: Carthamus tinctorius; 1:1:1:1:1 (w:w:w:w;w) which were extracted with aqueous infusion. Phytochemical screening was used to examined flavonoid and phenolic acid compounds using High-Performance Liquid Chromatography (HPLC) and the total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were determined. The antioxidant activity was determined using 2 2-diphenyl-1-picrylhydrazy (DPPH) radical scavenging and Ferric reducing antioxidant Power (FRAP) assay. The results showed that the second formula contained significantly higher TPC TFC flavonoid compounds and phenolic compounds than the first formula. Antioxidant activities with DPPH and FRAP assay of the second formula (16.88 0.25 mgTE/g and 62.97 2.45 mM Fe� E/g respectively) was significantly higher than the first formula (5.41 0.03 mgTE/g and 13.57 1.10 mM Fe� E/g respectively). These findings indicated that the second formula of the heart tonic herbal tea has an inhibitory free radical effect and has the potential to improve cardiovascular health following its consumption.
