摘要
研究了从遮荫植物（珍珠网、红色网和蓝色网）和非遮荫植物中分离的鼠尾草（Salvia officinalis L.）精油的产量、化学性质和抗氧化活性。分析结果可以看出，从遮蔽的叶子样本中，鼠尾草精油（SEO）的含量略高，只有少数例外。在蓝色光选择网下培养的样品的SEO产量最高（1.97 mL/100 g p.m.）。从鼠尾草中鉴定出38种不同的成分，分为7组。SEO的主要成分为顺式图琼（32.9-35.2%）、樟脑（19.0-25.6%）、反式图琼（8.6-13.1%）和1,8-桉树脑（9.4-11.0%）。所有测试样品的抗氧化活性均显示，在蓝色光选择网下生长的遮荫鼠尾草叶片在所有孵育时间（20.00-37.28 mL/100 g p.m.）下具有较强的抗氧化活性。这些研究证实，鼠尾草通过增加次生代谢产物（如EOs）的产生，对蓝光遮光有积极的反应。
Does photoselective netting influence yield, chemical composition and antioxidant activities of essential oils in cultivated sage?
Yield, chemical profile and antioxidant activity of sage (Salvia officinalis 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%), trans-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.
期刊介绍：
In an ever changing world, plant science is of the utmost importance for securing the future well-being of humankind. Plants provide oxygen, food, feed, fibers, and building materials. In addition, they are a diverse source of industrial and pharmaceutical chemicals. Plants are centrally important to the health of ecosystems, and their understanding is critical for learning how to manage and maintain a sustainable biosphere. Plant science is extremely interdisciplinary, reaching from agricultural science to paleobotany, and molecular physiology to ecology. It uses the latest developments in computer science, optics, molecular biology and genomics to address challenges in model systems, agricultural crops, and ecosystems. Plant science research inquires into the form, function, development, diversity, reproduction, evolution and uses of both higher and lower plants and their interactions with other organisms throughout the biosphere. Frontiers in Plant Science welcomes outstanding contributions in any field of plant science from basic to applied research, from organismal to molecular studies, from single plant analysis to studies of populations and whole ecosystems, and from molecular to biophysical to computational approaches.
Frontiers in Plant Science publishes articles on the most outstanding discoveries across a wide research spectrum of Plant Science. The mission of Frontiers in Plant Science is to bring all relevant Plant Science areas together on a single platform.
