ABSTRACT
The genus llex L. has been used as remedies in traditional Chinese medicine in Aquifoliaceae and beverages for thousands of years due to abundant pharmaceutical bioactivities. There are 600 species in genus Ilex L. containing various compounds such as terpenoids, saponins, glycosides, etc. Three species, I. cornuta, I. chinensis, and I. rotunda have been admitted in Chinese Pharmacopoeia 2015 to treat dyspepsia, stomatitis, and hyperactivity cough and protect the liver and kidney. Recent studies showed that several species have been daily drunk to promote human health and prevent cardiovascular diseases in the folk. Here we reviewed the genus Ilex L. in phytochemistry, ethnopharmacology, and pharmacology.
ABSTRACT
Objective: To investigate the chemical constituents in the leaves of Ilex kudingcha. Methods: Repeated column chromatography with silical gel, maroporous resin column, Sephadex LH-20, and preparative HPLC were used to isolate the chemical constituents, and their structures were elucidated on the basis of spectral data. Results: Eight compounds were isolated and identified as mateglycoside D (1), methyl caffeate (2), vanillin (3), gallic acid (4), caffeic acid (5), β-sitosterol (6), p-hydroxy-benzaldehyde (7), and ferulic acid (8). Conclusion: Compounds 2 and 7 are first obtained from the plants of Ilex L., and compounds 1,3,4, and 8 are first obtained from I. kudingcha.
