ABSTRACT

Objective:

To study the chemical constituents from the branches and leaves of Viburnum sargentii collected at Mountain Tai.

Methods:

The chemical constituents were isolated and purified by chromatographic methods, including silica gel, ODS, Sephadex LH-20 columns, and RP HPLC. The structures of the isolated compounds were identified by ESI-MS, 1D-NMR, and 2D-NMR data analyses, and compared with the literature data.

Results:

Thirteen compounds were obtained from the 95% ethanol extract of branches and the leaves of V. sargentii, and determined as α-amyrin (1), uvaol (2), 3α-ursolic acid (3), 11,12-dehydroursolic acid lactone (4), 3-O-acetyloleanolic aldehyde (5), oleanolic acid (6), betulinic acid (7), magnolin (8), (+)-eudesmin (9), (-)-epieudesmin (10), vibsanol (11), 3,4'-dimethoxylvibsanol (12), and α-asarone (13), respectively.

Conclusion:

Compound 12 (3,4'- dimethoxylvibsanol) is a new natural product, and compounds 1-11 and 13 are isolated from V. sargentii for the first time.
