由于一些假定的促进健康的生物活动，人们越来越注意天然植物化学品，特别是那些经常进入人类饮食的化学品。硫代葡萄糖苷（Glucosinolates，GLs）是青花菜（Brassica oleracea L.）变种意大利语Plenck）。他们有规律的饮食假设与降低各种肿瘤（肺癌、结肠癌、胰腺癌、乳腺癌、膀胱癌和前列腺癌）、一些退行性疾病（如阿尔茨海默氏症）的风险以及降低心血管疾病的发病率有关。GL的合成途径和调控机制主要在拟南芥中得到阐明。然而，近56个推定的基因已被确定为参与B。oleracea GL途径。人们普遍认为，有几个收获前（基因型，生长环境，文化习俗，成熟阶段等）。和收获后（收获、收获后处理、包装、储存等）影响西兰花中GL合成、概况和水平的因素。了解这些因素如何作用和相互作用，推动GL积累的可食用部分是必不可少的，开发新的西兰花品种具有改善的健康促进生物活性。在这方面，还没有任何系统和全面的审查概述了收获前和收获后因素对西兰花中糖脂积累的影响。因此，本文的目标是通过对最相关和最新的文献进行概括性的概述来填补这一空白。GL含量在收获前因素和收获后操作中存在显著的品种间差异，并进行了强调和讨论。该文件还强调，需要为每个特定的基因型调整特定的收获前和收获后程序，以在整个西兰花价值链中保持营养，新鲜的质量。
Owing to several presumed health-promoting biological activities, increased attention is being given to natural plant chemicals, especially those frequently entering the human diet. Glucosinolates (GLs) are the main bioactive compounds found in broccoli (Brassica oleracea L. var. italica Plenck). Their regular dietary assumption has been correlated with reduced risk of various types of neoplasms (lung, colon, pancreatic, breast, bladder, and prostate cancers), some degenerative diseases, such as Alzheimer's, and decreased incidence of cardiovascular pathologies. GL's synthesis pathway and regulation mechanism have been elucidated mainly in Arabidopsis. However, nearly 56 putative genes have been identified as involved in the B. oleracea GL pathway. It is widely recognized that there are several pre-harvest (genotype, growing environment, cultural practices, ripening stage, etc.) and post-harvest (harvesting, post-harvest treatments, packaging, storage, etc.) factors that affect GL synthesis, profiles, and levels in broccoli. Understanding how these factors act and interact in driving GL accumulation in the edible parts is essential for developing new broccoli cultivars with improved health-promoting bioactivity. In this regard, any systematic and comprehensive review outlining the effects of pre- and post-harvest factors on the accumulation of GLs in broccoli is not yet available. Thus, the goal of this paper is to fill this gap by giving a synoptic overview of the most relevant and recent literature. The existence of substantial cultivar-to-cultivar variation in GL content in response to pre-harvest factors and post-harvest manipulations has been highlighted and discussed. The paper also stresses the need for adapting particular pre- and post-harvest procedures for each particular genotype in order to maintain nutritious, fresh-like quality throughout the broccoli value chain.
