Yield, chemical profile and antioxidant activity of sage ( L.) essential oils (SEOs) isolated from shaded (pearl, red and blue color nets) or non-shaded plants have been investigated. Analysis of the results can be seen a slightly higher amount of sage essential oil (SEO) from the shaded leaves samples, with minor exceptions. The highest yield of SEO was obtained from the samples cultivated under the blue photo-selective nets (1.97 mL/100 g p.m.). A total of 38 different components were identified in sage and divided into 7 groups. The main components of SEO were cis-thujone (32.9-35.2%), camphor (19.0-25.6%), -thujone (8.6-13.1%) and 1,8-cineole (9.4-11.0%).The strong antioxidant activity of all tested samples showed SEO from shaded sage leaves grown under the blue photoselective net for the all incubation times (20.00-37.28 mL/100 g p.m.).These researches confirmed that sage responded positively to blue light shading through increased production of secondary metabolic products such as EOs.
对从遮荫（珍珠色、红色和蓝色网）或未遮荫植物中分离出的鼠尾草（L.）精油（SEOs）的产量、化学组成和抗氧化活性进行了研究。结果分析表明，除少数例外情况外，遮荫叶片样品中的鼠尾草精油（SEO）含量略高。在蓝色光选择网下种植的样品中，SEO的产量最高（1.97 mL/100 g干物质）。在鼠尾草中总共鉴定出38种不同成分，并分为7组。SEO的主要成分是顺式侧柏酮（32.9 - 35.2%）、樟脑（19.0 - 25.6%）、α-侧柏酮（8.6 - 13.1%）和1,8-桉叶素（9.4 - 11.0%）。在所有孵育时间（20.00 - 37.28 mL/100 g干物质）下，所有测试样品中，来自在蓝色光选择网下生长的遮荫鼠尾草叶片的SEO表现出较强的抗氧化活性。这些研究证实，鼠尾草通过增加诸如精油等次生代谢产物的产量，对蓝光遮荫做出了积极反应。
