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.

对西番莲植物中的酚类化合物的系统评价：探索生物多样性的食品，营养和流行药物

西番莲植物在粮食和营养生物多样性方面具有战略意义。我们应用了系统评价方案的程序来研究鉴定西番莲酚类化合物的最新技术植物。使用六个数据库和七个关键字的组合进行了自动文献检索。包括所有分析，色谱和光谱方法。根据研究的鉴定方法，酚类和提取方法对研究进行分类。总共发现了8592个摘要，从中选择了122个研究以进行完整阅读，并选择了82个进行进一步分析。系统地提取了植物的提取技术，评估部位和鉴定方法。叶研究最为突出（54.4％），西番莲有34种进行了评估，通常发现了Orientin，Isoorientin，Vitexin，Isovititexin。高效液相色谱-二极管阵列检测器是最常用的技术，尽管研究发现了其他未知结构，但并未阐明，但整个研究过程中都使用了相同的结构。需要加强对更敏感技术的核磁共振和质谱的使用，以鉴定西番莲中检测到的其他非常规化合物，以增强这些植物中生物活性化合物的理解。
