The chemical composition of the different plant parts of green (Hibiscus cannabinus L. cv. Jangdae) and purple (H. cannabinus L. cv. Jeokbong) kenaf cultivars were investigated using high-performance liquid chromatography. Ten carotenoid and phenolic compounds were quantified in the different parts of green and purple kenaf. The accumulation of carotenoids and phenolic compounds in the different parts of both cultivars was slightly different. The total carotenoid content in all parts of purple kenaf was higher than that in green kenaf. In particular, lutein, β-carotene, and 9Z-β-carotene were found in all the plant parts of both purple and green kenaf. Most levels of these 3 carotenoids were higher in all parts of the purple cultivar than those found in the green cultivar. According to the detected phenolic compound content, the leaves of the green cultivar contained a higher level of total phenolics, even though the most levels of the individual phenolic compounds were higher in the purple cultivar due to the level of kaempferitrin, a major compound found in kenaf, being much higher than the levels observed for the other phenolic compounds. However, the flowers and stems of the purple cultivar had a higher level of total phenolics. Among the 10 different phenolic compounds, 7 (4-hydroxybenzoic acid, chlorogenic acid, p-coumaric acid, ferulic acid, benzoic acid, rutin, and kaempferol) were present in all the plant parts of both kenaf cultivars. Purple kenaf leaves contain higher levels of 4-hydroxybenzoic acid, chlorogenic acid, and rutin, whereas the purple cultivar flowers have higher levels of p-coumaric acid, ferulic acid, and benzoic acid. This study provides valuable information on the chemical composition of different plant parts of green and purple kenaf cultivars.

绿色（芙蓉大麻L. cv。Jangdae）和紫色（H.大麻）不同植物部分的化学组成。L.简历 Jeokbong）洋麻品种使用高效液相色谱法进行了研究。在绿色和紫色洋麻的不同部位定量了十种类胡萝卜素和酚类化合物。两个品种不同部位的类胡萝卜素和酚类化合物的积累略有不同。紫色洋麻各部位的总类胡萝卜素含量高于绿色洋麻。特别是在紫麻和绿麻的所有植物部位都发现了叶黄素，β-胡萝卜素和9Z-β-胡萝卜素。这三种类胡萝卜素的大部分水平在紫色品种的所有部位都高于绿色品种。根据检测到的酚类化合物含量，绿色品种叶片中的总酚类含量较高，即使紫色品种中大多数酚类化合物的含量较高，这是由于山麻铁素（一种在洋麻中发现的主要化合物）的含量远高于其他酚类化合物的含量。但是，紫色品种的花和茎中总酚含量较高。在10种不同的酚类化合物中，有7种（4-羟基苯甲酸，绿原酸，对麻香酸，阿魏酸，苯甲酸，芦丁和山ka酚都存在于两个洋麻品种的所有植物部分中。紫色洋麻叶含有较高含量的4-羟基苯甲酸，绿原酸和芦丁，而紫色栽培品种花具有较高含量的对香豆酸，阿魏酸和苯甲酸。这项研究为绿色和紫色洋麻品种不同植物部分的化学组成提供了有价值的信息。
