Comparison and correlation analysis of flavonoids and chlorogenic acid contents in different strains of Acer truncatum

Abstract

The morphological characteristics, total flavonoid content (TFC) and chlorogenic acid (CGA) contents of leaves from different strains of Acer truncatum were analyzed with the goal of providing guidance for the development and utilization of Acer truncatum leaves (ATLs) and a selection system for the medicinal cultivar of Acer truncatum species. The morphological characteristics of the ATLs were determined using conventional methods, and TFC and CGA were used to determine the ATL extract by UV spectrophotometry and HPLC. The results showed that most traits significantly differed among the ATL morphologies of different strains and that considerable variability was found between different strains in both TFC (15.04 to 35.18 mg/g) and CGA (0.17 to 0.77 mg/g). The CGA content of ATLs could be improved by selecting for leaf lobe length (Pearson correlation coefficient of 0.551*). Principal component analysis showed that the variations in the ATLs were primarily determined by four comprehensive factors: shape, TFC, angle, and petiole. The TDPSOS method was used to obtain the quality of medicinal Acer truncatum resources: Clone No. '1-6' , Clone No. '1-7' and Clone No. '5-4' .

Structural Characterization of the Acer ukurunduense Chloroplast Genome Relative to Related Species in the Acer Genus

“…Acer L. species have been used for several thousand years in China, have gained high economic value, and are now among the most important timber trees ( Wu et al, 2008 ; Saeki and Murakami 2009 ; Dormontt et al, 2020 ). Flavonoids, tannins, terpenoids, sterols, alkaloids, diarylheptanoids, diarylheptanoids, and others have been isolated from Acer , possessing high bioactivity and exerting pharmacological effects ( Tang et al, 2012 ; Ren and Feng, 2018 ; Yang et al, 2018 ; Hou et al, 2019 ; Liang et al, 2019 ; Piao et al, 2020 ; Kausar et al, 2021 ). Additionally, in Chinese folk medicine, Acer has also been widely used to treat angina pectoris, coronary artery cirrhosis, and cardiac–cerebral vascular disease .…”

Comparison of Seasonally Adaptive Metabolic Response Strategies of Two Acer Species

“…In addition to excellent landscape applications, maple species are valued as primary raw materials for wood, maple sugars and syrups, and medicinal or bioactive compounds [28][29][30]. The ecological role [31,32] of Acer L. plants and the physiological functions [33,34] of particular species are now widely studied. However, the comparison of the life processes of different species of plants within the same genus has not been studied in detail.…”
