A novel homosesquiterpenoid from the stems of Cinnamomum burmanii.

A novel homosesquiterpenoid, burmanol (1), along with 16 known compounds, including one triterpenoid, one quinol, two chlorophylls, two coumarins, two steroids, three lignans and five benzenoids were obtained from the stems of Cinnamomum burmanii (Lauraceae). The structures of these compounds were determined on the basis of spectroscopic analysis.

Amides from the stems of Cinnamomum burmannii.

A novel amide, cinnabutamine (1), along with five known amides, cinnaretamine (2), N-trans-caffeoyl-5-hydroxytyramine (3), N-trans-feruloyltyramine (4), N-trans-feruloyl-5-methoxytyramine (5) and N-cis-feruloyl-5-methoxytyramine (6), were isolated from the stems of Cinnamomum burmannii (Lauraceae). Their structures were characterized and identified by spectral analysis.

Isolation of a new monoterpenic ester from the leaves of Michelia compressa (Maxim.) Sargent var. formosana Kanehira (Magnoliaceae).

Pressafonin A (1) and pressafonin B (2), two new Michelia monoterpenic esters, have been isolated from Michelia compressa (Maxim.) Sargent var. formosana Kanehira (Magnoliaceae), and their structures are determined on the basis of spectroscopic analysis.
