Abstract

Phyllostachys glauca McClure leaves (PML), as economical natural product material, contain abundant phenols, particularly flavonoids, with significant biological activities that contribute to their widespread applications in food, pharmaceutical, and cosmetic industries. To study the significant phenols in PML, an ultrasound-assisted deep eutectic solvent extraction method with high efficiency and low toxicity was established for extracting the phenols from PML and the bamboo leaves of 17 other bamboo species. Using the Ultra Performance Liquid Chromatography (UPLC) method, the content of phenols in the leaves of the 18 bamboo species was determined. PML were found to contain neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isoorientin, and orientin at contents of 0.793 ± 00.17 mg/g, 0.491 ± 0.0081 mg/g, 0.485 ± 0.0043 mg/g, 0.465 ± 0.0021 mg/g, and 0.044 ± 0.0005 mg/g, respectively, with a total content of 2.278 mg/g. These contents were significantly higher than those found in the leaves of 17 other bamboo species. Additionally, the significant phenols, neochlorogenic acid, chlorogenic acid, and cryptochlorogenic acid were found simultaneously in the leaves of 15 bamboo species, especially in PML. Therefore, PML can be viewed as the natural product material with considerable application values, owing to its abundant phenols, and can exhibit its importance in utilizing neochlorogenic acid, chlorogenic acid, and cryptochlorogenic acid as resources.
