摘要

墨西哥可可豆果实中含有多酚、类黄酮和花青素,而叶片中的羽扇豆醇、α- 和 β-amyrin已被 HPLC 鉴定。然而,高效液相色谱法对五环三萜类化合物(PTs)的分辨率较低,这是一个局限。此外,C. uvifera 果实的挥发性特征仍然未知。因此,本研究旨在通过 CG-MS 分析鉴定 C. uvifera 叶和果提取物中的 PTs,并通过顶空固相微萃取确定 C. uvifera 果肉的挥发性特征。结果显示,标准羽扇豆醇、α- 和 β-amyrin的三甲基硅烷化化合物表明硅烷化反应是合适的。这些三甲基硅烷基化化合物在叶片和果实提取物中得到了鉴定。果实挥发性特征显示存在 278 种酯、20 种萜烯、9 种醛、5 种醇和 4 种酮。果实中的酯类和萜烯含量较高。由于具有调味特性,酯类是食品、化妆品和制药业的必需品。此外,果实中的萜烯,如薄荷酮、β-榄香烯、杜松烯和β-石竹烯,具有抗癌和植物病原体制剂的潜力。研究结果表明,气相色谱-质谱法可替代高效液相色谱法鉴定 PTs。此外,鉴定果实中的挥发性化合物将提高这种植物的价值并扩大其应用范围。鉴定墨西哥枸橘中的 PTs 和挥发性化合物有助于更好地了解这种植物的潜在益处。这将增加墨西哥枸橘的新鲜消费量,或作为营养保健品或药品中的功能成分。

Mexican Coccoloba uvifera L. Leaf and Fruit Extracts: Identification of Pentacyclic Triterpenes and Volatile Profile by GC-MS.

Mexican Coccoloba uvifera fruit contains polyphenols, flavonoids, and anthocyanins, while in the leaves, lupeol, α- and β-amyrin have been previously identified by HPLC. However, the low resolution by HPLC of pentacyclic triterpenes (PTs) is a limitation. Moreover, the volatile profile of C. uvifera fruit is still unknown. Therefore, this study aimed to identify PTs in C. uvifera leaf and fruit extracts by CG-MS analysis and to determine the volatile profile of C. uvifera pulp by headspace solid-phase microextraction. The results showed trimethylsilylated compounds of standards lupeol, α- and β-amyrin, indicating that the silylation reaction was suitable. These trimethylsilylated compounds were identified in leaf and fruit extracts. The fruit volatile profile revealed the presence of 278 esters, 20 terpenes, 9 aldehydes, 5 alcohols, and 4 ketones. The fruit showed a high content of esters and terpenes. Due to their flavour properties, esters are essential for the food, cosmetics, and pharmaceutics industries. Moreover, terpenes in the fruit, such as menthone, β-elemene, junipene, and β-caryophyllene have the potential as anticancer and phytopathogen agents. The results indicated that GC-MS is an alternative to HPLC approaches for identifying PTs. Besides, identifying volatile compounds in the fruit will increase the value of this plant and expand its application. Identifying PTs and volatile compounds in Mexican C. uvifera leads to a better understanding of the potential benefits of this plant. This would increase the consumption of Mexican C. uvifera fresh or as functional ingredients in nutraceutical or pharmaceutical products.
