Chemical composition of medicinal ingredients and the formulation of a healthsupporting tea from red jujube, goji berries, ginger, and cinnamon

Abstract

The herbal tea in this study was prepared from several natural medicinal ingredients to protect and enhance health. The main medicinal ingredients combined to produce the tea include: red jujube (Ziziphus jujuba), goji berry (Lycium barbarum), ginger (Zingiber officinale), and cinnamon (Cinnamomum verum). The chemical composition of these medicinal ingredients was determined by the gas chromatography - mass spectrometry (GC-MS) method. The composition of natural medicinal herb extracts contains compounds that have anti-inflammatory, antibacterial, antioxidant, cancerpreventive, digestive, cardiovascular-support properties, blood pressure regulation, and blood lipid reduction effects, and does not contain substances harmful to health. The nutritious tea is made in two forms: instant tea and tea bags. The tea preparation formula is determined through a survey to determine the ratio of medicinal ingredients. Instant tea has the best quality and flavour when combining herbal extracts in the ratio: 45% red jujube + 20% goji berry + 15% ginger + 5% cinnamon + 15% isomalt. Tea bags have the best quality and flavour when processed from finely ground herbs, dried to a moisture content of <10%, and combined in the ratio: 60% red jujube + 25% goji berry + 5% ginger + 5% cinnamon + 5% isomalt.
