1. Eight kinds of flowers were selected including Lily, Honeysuckle, Globe amaranth, Tribute Chrysanthemum, tea plant flower, Rose, Hibiscus sabdariffa and Saffron.
    选用八种常见饮用花卉，如百合花、金银花、千日红、贡菊、茶花、玫瑰花、玫瑰茄、藏红花，分别采用电感耦合等离子体发射光谱法和三氯化铝比色法检测其微量元素和黄酮类化合物的舍量。

2. Hibiscus protocatechuic acid, a simple phenolic compound, isolated from Hibiscus sabdariffa L.
    原儿茶酸（protocatechuic acid，PCA）是一简单多酚类化合物，经由乾燥的洛神花萃取而来的。

3. In our previous studies, we explored that both protocatechuic acid and the aqueous extract of its original plant, Hibiscus Sabdariffa, showed strong inhibitory effects on the negative charge increasing of protein moiety in oxLDL and on the lipid peroxidation of lipid moiety in oxLDL. At present, we further investigate the effects of PCA and HSE on LDL oxidation.
    在先前的研究中，我们已经发现原儿茶酸和洛神花水萃取物对於氧化型LDL所表现的负电荷增加及脂肪酸氧化有抑制氧化的作用，在本实验中我们以PCA和HSE进一步探讨其对抗LDL氧化的作用强弱。
