The issues such as how to avoid growing old and how to strengthen the anti-oxidant are therefore in prevailing. Malignant tumour, cerebrovascular disease, cardiovascular disease, and diabetes are among ten major death causes in Taiwan. Current researches verified that these diseases not only related to aging structure, but also showed that they may all had something to do with the injury of oxidizing the human body caused by the free radical or the active oxygen. 　 　　The purpose of this research is therefore to probe into anti-oxidant composition and activation included in the following four kinds of folk prescription, namely: Chrysanthemum morifolium, Hibiscus sabdariffa, Lycium chinese, and Ziziphus jujube. In the meantime, they were also reconfigured as the drink of formula (compound prescription) according to the statistical methodology in order to investigate their optimal result of anti-oxidizing effects. 　 　　In this regard, this research examined separately four kinds of folk prescriptions and formula mentioned above; and analyzed their scavenging capacity of DPPH, total antioxidant activity, reduction ability, flavonoid contents, and phenol contents. In addition, the relation among flavonoids, phenol, and anti-oxidant ability with SPSS were also analyzed. Analysis results showed that: 1. In the order of flavonoid contents, they were Chrysanthemum morifolium (12.38), Hibiscus sabdariffa (11.60), formula (5.41), Ziziphus jujube (1.59), and Lycium chinese (0.77 mg quechitin/g dw); 2. In the order of phenol contents, they were Chrysanthemum morifolium (25.83), Hibiscus sabdariffa (23.05), formula (11.54), Lycium chinese (5.22), and Ziziphus jujube (2.83 mg gallic acid /g dw). 　 　　Their flavonoid contents and phenol contents had linear relations with the anti-oxidant activation in separate. Moreover, the scavenging capacity of DPPH, total antioxidant activity and reduction ability of all samples were raised with the increase of their concentrations. 　 　　Chrysanthemum morifolium, hibisus, and formula had better anti-oxidant efficiency: 1. In the order of their effective concentrations (EC50) in scavenging capacity of DPPH, they were Chrysanthemum morifolium (0.09), Hibiscus sabdariffa (0.90), and formula (0.94 g/L). 2. In the order of the effective concentrations in reduction ability (OD1.0), they were Chrysanthemum morifolium (0.81), formula (1.18), Hibiscus sabdariffa (1.21), and Lycium chinese (1.25g/L). 3. In the order of effective concentrations (EC50) in total anti-oxidant ability, they were Chrysanthemum morifolium (0.75), Hibiscus sabdariffa (0.93), and formula (1.37 g/L). Based on the above research results, the Chrysanthemum morifolium, hibiscus, and formula had better anti-oxidant efficiency because they had more flavonoids and total phenol compositions. Although Ziziphus jujube didn’t have too much anti-oxidant efficiency, it could increase the flavor in the drink of formula; nevertheless, it has the functions of mixing with hundreds of other Chinese herbal medicines. The Hibiscus sabdariffa had very good color and luster, which not only can beautify the appearance of the formula drink, but also sometimes produce amazing effects and make it additional curative. If the Hibiscus sabdariffa could be further processed, it would be helpful for developing the mechanism of natural food. Furthermore, it would elevate the economic benefits and application value of the Chinese herbal medicine. The Hibiscus sabdariffa will notably play a major role in developing its anti-oxidant efficiency to prevent people from growing old and to promote human health.
