Abstract

Abstract: Phytochemical investigations on the immature buds of Cinnamomum cassia (cassia buds) led to the isolation of fifteen compounds, including two phenylmethanol glycosides (1 and2 ), two phenylethyl glycosides (3 –5 ), two butanol glycosides (6 and7 ), a megastigmane sesquiterpenoid (8 ), a pair of isomeric monoterpenoids (9 ) and their glycosides (10 ), a monoterpenoid glycoside (11 ), a geraniol type monoterpenoid (12 ), two phenolic glycosides (13 and14 ), and cinnamic acid (15 ). Their structures were identified by spectroscopic analyses and comparison with literature data. Compounds1, 2, and4 –13 were isolated from Cinnamomum cassia for the first time, and compounds1, 2, 4 –7, and9 –11 were reported in the Lauraceae family for the first time. The chemotaxonomic significance of these compounds was discussed. Graphical abstract: Fifteen compounds belonging to seven structural types were isolated from the immature buds of Cinnamomum cassia. Their structures were identified by spectroscopic analyses and comparison with literature data. Compounds1, 2, and4 –13 were isolated from Cinnamomum cassia for the first time, and compounds1, 2, 4 –7, and9 –11 have not been reported in Lauraceae family. The chemotaxonomic significance of the isolated compounds was summarized. Highlights: Fifteen compounds1 –15 were isolated from the immature buds of Cinnamomum cassia. Compounds1, 2, and4 –13 were isolated from Cinnamomum cassia for the first time. Compounds1, 2, 4 –7, and9 –11 were isolated from the Lauraceae family for the first time. The chemotaxonomic significance of the identified fifteen compounds was discussed.
