Schefflerins A-G, New Triterpene Glucosides from the Leaves of Schefflera arboricola

“…The 1-BuOH-soluble fraction was separated by means of various chromatographic procedures including column chromatography (CC) on a highly porous synthetic resin (Diaion HP-20), then normal silica gel and reversed-phase octadecyl silica gel (ODS) CC, droplet counter-current chromatography (DCCC), and high-performance liquid chromatography (HPLC) to afford 10 compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). The details and yields are given under Experimental.…”

3-Epicabraleahydroxylactone and Other Triterpenoids from Camellia Oil and Their Inhibitory Effects on Epstein-Barr Virus Activation

“…Identification of 5a was performed by 13 C-NMR comparison with data in the literature. 16) TPA was purchased from ChemSyn Laboratories (Lenexa, KS, U.S.A.). The cell culture reagents, n-butyric acid, and other reagents were purchased from Nacalai Tesque, Inc. (Kyoto, Japan).…”
