Abstract

Every year, more than 50 million tons of Helianthus annuus L. are produced mainly for the sunflower oil industry. It is a plant consumed worldwide, due to its use in feeding and traditional medicine for the prevention of some cardiovascular diseases, as anti-inflammatory, antimicrobial, antioxidant and antihypertensive, among others. Sunflower has a great diversity of metabolites, being especially rich in terpene compounds with close to 400 different molecules reported, including volatile mono and sesquiterpenes. Among these terpenic components of sunflower, sesquiterpenes as helibisabonols, helianuols and heliangolides, diterpenes (ent-kaurenes or ent-trachylobanes and ent-atisarenes compounds) or apocarotenoids (ionone compounds and strigolactones) are worthy to be underlined. Many of these compounds have allelopathic activity. On the other hand, sesquiterpene lactones and diterpene compounds have strong insect antifeedant, antifungal and allelopathic activities. Additionally, the essential oil (rich in α-pinene) has antifungal properties. All these biological activities suggest that Helianthus annuus has great potential for natural crop protection. Since the main sunflower crop residue is the flower head, we have revised the plant-protection properties of flowerhead components to highlight the potential valorization of that residue for the production of biopesticides.

向日葵（Helianthus annuus L.）中萜类化合物的多样性及其在作物保护中的潜力

每年生产的 5 000 多万吨葵花籽主要用于葵花籽油工业。向日葵是一种世界性的食用植物，因为它可作为抗炎、抗菌、抗氧化和降血压等药物用于预防某些心血管疾病。向日葵的代谢物种类繁多，尤其富含萜烯化合物，据报道有近 400 种不同的分子，包括挥发性单萜和倍半萜。在向日葵的这些萜类成分中，值得强调的是倍半萜类化合物，如 helibisabonols、helianuols 和 heliangolides，二萜类化合物（ent-kaurenes 或 ent-trachylobanes 和 ent-atisarenes 化合物）或 apocarotenoids（离子化合物和 strigolactones）。其中许多化合物都具有等位病理学活性。另一方面，倍半萜内酯和二萜化合物具有很强的昆虫抗药性、抗真菌性和等位病理学活性。此外，精油（富含 α-蒎烯）具有抗真菌特性。所有这些生物活性表明，向日葵具有天然作物保护的巨大潜力。由于向日葵作物的主要残留物是花头，我们对花头成分的植物保护特性进行了修订，以突出该残留物生产生物农药的潜在价值。

期刊介绍： Phytochemistry Reviews is the sole review journal encompassing all facets of phytochemistry. It publishes peer-reviewed papers in six issues annually, including topical issues often stemming from meetings organized by the Phytochemical Society of Europe. Additionally, the journal welcomes original review papers that contribute to advancing knowledge in various aspects of plant chemistry, function, biosynthesis, effects on plant and animal physiology, pathology, and their application in agriculture and industry. Invited meeting papers are supplemented with additional review papers, providing a comprehensive overview of the current status across all areas of phytochemistry.
