Camehakosides A–E, Five Undescribed Acylated Oleanane Saponins From the Leaves of <i>Camellia hakodae</i> With Their α‐Glucosidase Inhibitory Activity
Five undescribed acylated oleanane saponins (1-5), together with five known compounds (6-10) were isolated from the leaves of Camellia hakodae. Their chemical structures were determined by infrared, high-resolution electrospray ionization mass spectrometry, and one-dimensional and two-dimensional nuclear magnetic resonance spectra. Compounds 1-10 significantly inhibited α-glucosidase with IC<sub>50</sub> values ranging from 2.11 ± 0.18 to 10.42 ± 0.41 µM.
