向日葵属植物包括52种以及许多亚种，全部都是起源于北美洲，但有许多种已经作为食物或花卉被引进到世界各地种植。向日葵约100种，大部产北美，我国引入栽培的有向日葵 H. annuus L. 等4种，各地多有栽培，果供食用或榨油。
本论文对向日葵根中化学成分进行了深入研究，并对向日葵属植物的化学成分、生物活性和药理作用做了简要综述。
In these paper, the chemical constituents in the root of sunflower were studied further, the progress in chemical compositions and pharmacological research were overviewed.
植物至少有两个学名———一个属名，是总称，用大写，另一个是小写字母的种名，更加专属，比如，洋姜jerusalem artichoke就是向日葵属菊芋helianthus tuberosus。
Plants have at least two names - a genus name, which is general and capitalised, and a lower-case species name that is more specific, for example, the Jerusalem artichoke is Helianthus tuberosus.
