Scutellaria (skullcap) are important medicinal plants. Scutellaria baicalensis and S.barbata have been used in Chinese traditional medicine, while S. incana and S. lateriflora were used as herbal medicines by Native Americans. In this work, the essential oils of Scutellaria baicalensis Georgi, Scutellaria barbata D. Don, Scutellaria incana Biehler, and Scutellaria lateriflora L. were obtained from plants cultivated in south Alabama and analyzed by gas chromatographic techniques, including chiral gas chromatography. The most abundant components in the Scutellaria essential oils were 1-octen-3-ol (31.2% in S. incana), linalool (6.8% in S. incana), thymol (7.7% in S. barbata), carvacrol (9.3% in S. baicalensis), (E)-β caryophyllene (11.6% in S. baicalensis), germacrene D (39.3% in S. baicalensis), (E)-nerolidol (10.5% in S. incana), palmitic acid (15.6% in S. barbata), phytol (19.7% in S. incana), and linolenic acid (8.0% in S. barbata). These analyses of the essential oil compositions and enantiomeric ratios of predominant aromatic molecules add to our understanding of the medicinal phytochemistry of the genus Scutellaria.

黄芩（skullcap）是重要的药用植物。Scutellaria baicalensis和S.barbata已被用于中药，而S. incana和S. lateriflora则被美洲原住民用作草药。在这项工作中，黄芩、Scutellaria barbata D. Don 、Scutellaria incana Biehler 和Scutellaria lateriflora L. 的精油是从阿拉巴马州南部种植的植物中提取的，并通过气相色谱技术（包括手性气相色谱）进行分析。黄芩中含量最多的成分精油是 1-octen-3-ol（S. incana 中的31.2% ）、芳樟醇（S. incana 中的6.8% ）、百里酚（S. barbata 中的7.7% ）、香芹酚（S. baicalensis 中的9.3% ），（E )-β 石竹烯（11.6% 在S. baicalensis 中）、germacrene D（在S. baicalensis 中39.3% ）、（E）-橙花醇（在S. incana 中为10.5% ）、棕榈酸（在S. barbata 中为15.6% ）、植醇（S. incana 中的19.7% ）和亚麻酸（S. barbata 中的8.0%））。这些对精油成分和主要芳香分子的对映体比率的分析增加了我们对黄芩属药用植物化学的理解。
