Triterpenoids from with anti-hyaluronidase activities.

Phytochemical study on 90% ethanol extract from the green walnut husks of Maxim. resulted into the isolation of three undescribed triterpenoids, juglansmanoids A-C (-). Structural elucidation of all the compounds were performed by spectral methods such as 1D and 2D (H-H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass spectrometry.
