Isolation and characterization of phenylethanoid glycosides from Clerodendron bungei

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.
