Abstract
Background: Rubus alceifolius Poir leaves are a widely distributed medicinal plant material in the Eastern Hemisphere. However, there has been no report regarding their chemistry until now. Methods: Fresh R. alceifolius leaves were treated using a set of experimental protocols to prepare a lyophilized aqueous extract. Subsequently, the extract was qualitative and quantitatively analyzed using the database-affinity ultra-high-performance liquid chromatography-quadrupole-Exactive- Orbitrap-tandem mass spectrometry (UHPLC-Q-Exactive-Orbitrap-MS/MS) technology. Results: Based on MS/MS elucidation and comparison with the database in UHPLC-Q-Exactive- Orbitrap-MS/MS apparatus, 33 compounds were qualitatively identified. Especially, 12 isomers were strictly distinguished, including apigenin vs. 2'-hydroxydaidzein, luteolin 7-O-glucuronide vs. scutellarin, (+) catechin vs. (-) epicatechin, 3-O-caffeoylquinic acid vs. 4-O-caffeoylquinic acid vs. 5-Ocaffeoylquinic acid, and 3,4-O-dicaffeoylquinic acid vs 3,5-O-dicaffeoylquinic acid vs 4,5-Odicaffeoylquinic acid. In addition, 21 non-isomeric compounds, such as ellagic acid and gallic acid, were also found under negative or positive ion models. The quantitative analysis suggested that ellagic acid was found to be of the highest level (133.00 ± 3.50 μg/g), while (+)-4-cholesten-3-one was calculated to be of the lowest level (0.035 ± 0.0050 μg/g). Conclusion: These findings will help to understand the substance basis of the traditional medicinal functions of R. alceifolius leaves and to find their suitable quality markers.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
