Medicinal plants have been used since antiquity to cure illnesses and injuries. In the last few decades, natural compounds extracted from plants have garnered the attention of scientists and the species are no exception. Several species and cultivars are widespread in Asia, namely in China, Japan, Vietnam and India, being also identified in western countries like Portugal. Tea and oil are the most valuable and appreciated subproducts extracted from and , respectively. The economic impact of these species has boosted the search for additional information about the genus. Many studies can be found in the literature reporting the health benefits of several Camellia species, namely , and . These species have been highlighted as possessing antimicrobial (antibacterial, antifungal, antiviral) and antitumoral activity and as being a huge source of polyphenols such as the catechins. Particularly, epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and specially epigallocatechin-3-gallate (EGCG), the major polyphenols of green tea. This paper presents a detailed review of species' antioxidant properties and biological activity.
药用植物自古以来就被用于治疗疾病和损伤。在过去的几十年中，从植物中提取的天然化合物引起了科学家的关注，[植物名称]也不例外。有几个品种和栽培品种在亚洲广泛分布，特别是在中国、日本、越南和印度，在葡萄牙等西方国家也有发现。茶和油是从[植物名称]中提取的最有价值和最受赞赏的副产物。这些物种的经济影响促使人们对[植物属名]进行了更多的信息搜索。许多研究报告了几种山茶属植物的健康益处，特别是[植物中文名]、[植物中文名]和[植物中文名]。这些物种具有抗菌（抗细菌、抗真菌、抗病毒）和抗肿瘤活性，是多酚的重要来源，如儿茶素。特别是表没食子儿茶素（EC）、表没食子儿茶素没食子酸酯（EGCG）、表儿茶素-3-没食子酸酯（ECG），特别是表没食子儿茶素-3-没食子酸酯（EGCG），是绿茶中的主要多酚。本文详细综述了[植物属名]的抗氧化特性和生物活性。
