Passiflora plants are strategic in the context of biodiversity for food and nutrition. We applied the procedures of a systematic review protocol to study the state of the art on identification of phenolic compounds from Passiflora plants. An automated literature search was conducted using six databases and a combination of seven keywords. All the analytical, chromatographic, and spectroscopic methods were included. The studies were classified according to their method of identification, phenolic classes, and method of extraction. In total, 8,592 abstracts were found, from which 122 studies were selected for complete reading and 82 were selected for further analysis. Techniques of extraction, evaluated parts of the plant and methods of identification were systematized. Studies with leaves were most conspicuous (54.4%), 34 species of Passiflora were evaluated and orientin, isoorientin, vitexin, isovitexin were commonly found structures. A High Performance Liquid Chromatography-diode array detector was the technique most applied, with which the same structures were identified all through the studies, although other unknown structures were detected, but not elucidated. The use of Nuclear Magnetic Resonance and Mass Spectrometry, which are more sensitive techniques, needs to be intensified, to identify other unconventional compounds detected in Passiflora, to enhance the comprehension of the bioactive compounds in these plants.
西番莲植物在生物多样性方面对于食物和营养具有战略意义。我们应用系统评价方案的程序来研究鉴定西番莲植物中酚类化合物的最新技术。使用六个数据库和七个关键词的组合进行了自动化文献搜索。包括了所有的分析、色谱和光谱方法。根据鉴定方法、酚类化合物类别和提取方法对研究进行了分类。总共发现了 8592 篇摘要，其中有 122 篇研究被选择进行全文阅读，82 篇被选择进行进一步分析。提取技术、植物评估部分和鉴定方法得到了系统化。以叶片为研究对象的研究最为显著（54.4%），评估了 34 种西番莲，发现Orientin、Isoorientin、Vitexin 和 Isovitexin 是常见的结构。高效液相色谱-二极管阵列检测器是应用最广泛的技术，通过这些研究鉴定出了相同的结构，尽管检测到了其他未知结构，但未进行阐明。需要加强使用更敏感的技术，如核磁共振和质谱，以鉴定在西番莲中检测到的其他非常规化合物，从而增强对这些植物中生物活性化合物的理解。
