A new apigeninglycoside, apigenin 6-C-galactosyl-6"-O-beta-galactopyranoside (1), isoorientin, and a mixture of orientin and isovitexin were isolated from leaves of Cecropia lyratiloba by high-speed countercurrent chromatography using a solvent system containing ethyl acetate, butanol, methanol and water. The structural elucidation of 1 was based on NMR spectroscopy. 
Bioactive saponins and glycosides. XXVIII. New triterpene saponins, foliatheasaponins I, II, III, IV, and V, from Tencha (the leaves of Camellia sinensis).
TLDR
Among the new saponins isolated, foliatheasaponins II and III were found to inhibit release of beta-hexosaminidase, as a marker of antigen-induced degranulation, in RBL-2H3 cells.
Two new 11α,12α-epoxy-ursan-28,13β-olides and other triterpenes from Cecropia catharinensis
TLDR
Three new triterpenes, 2α-acetoxy-3β,19α-dihydroxy-11α,12α-epoxy-ursan-28,13β-olide and 2-O-acetyl-euscaphic acid together eight known triterPenes were isolated from the roots and stems of Cecropia catharinensis.
New features on the fragmentation and differentiation of C-glycosidic flavone isomers by positive electrospray ionization and triple quadrupole mass spectrometry.
TLDR
Some general guidelines and two new diagnostic product ions have been proposed for the differentiation of C-6- and C-8-flavonoid glycosides and mass spectra of a flavone di-C-glycoside detected in lemon juice have been studied and interpreted.
Strategies of solvent system selection for the isolation of flavonoids by countercurrent chromatography.
TLDR
This paper proposes strategies of solvent system selection for the isolation of flavonoids by CCC, based on data from the literature, plus incorporation of own practical experiences, to show the versatility of this technique.
