From the hook of Uncaria sinensis, a new alkaloid, isorhynchophyllic acid was isolated and its structure was elucidated by spectral data and chemical reaction.
A new iridoid, 6'-acetyl asperuloside was isolated from the whole plant of Hedyotis crysotrichae. Its structure has been elucidated by means of H-1-NMR and C-13-NMR spectra.
