[Chemical constituents from flower of Lonicera fragrantissima].

ABSTRACT

OBJECTIVE: To study the chemical constituents from the flower of Lonicera fragrantissima. METHODS: The chemical constituents were isolated and purified by means of several chromatographic techniques, and their structures were elucidated by spectroscopic methods. RESULTS: Nine compounds were isolated and identified as chlorogenic acid (1), caffeic acid (2), secologanoside (3), secoxyloganin(4), loganin (5), sucrose (6), myo-inositol (7), rutin (8), and chrysoeriol-7-O-ß-D-glucoside (9). CONCLUSION: Compounds 2-9 are obtained from this plant for the first time.
