[Isolation and characterization of phenylethanoid glycosides from Clerodendron bungei]
1School of Pharmaceutical Sciences, Peking University, Beijing 100083, China.
Aim:
To study the chemical constituents from Clerodendron bungei Steud.
Methods:
The compounds were isolated and purified by various chromatographic techniques and identified by their physicochemical properties and spectral data.
Results:
Ten phenylethanoid glycosides were isolated and identified as clerodendronoside (1), acteoside (2), isoacteoside (3), cistanoside C (4), jionoside C (5), leucosceptoside A (6), cistanoside D (7), campneoside I (8), campneoside II (9), cistanoside F (10).
Conclusion:
Compound 1 is a new phenylethanoid glycoside, while compounds 4-10 are obtained from this plant for the first time.
