Abstract: Rosemary and sage are common spices used in food. In our recent
search of cancer chemopreventive agents from spices, the alcohol extracts of
rosemary and sage showed strong antumorigenic activities. Rosemary and sage
extracts contain active antioxidative factors such as phenolic diterpenes,
flavonoids and phenolic acids. Here we discuss chromatographic methods used to
separate and purify compounds from these spices and MS and NMR spectrometry to
identify the isolated compounds. Several new compounds isolated from sage were
determined to be
6-O-caffeoyl-\beta-D-fructofuranosyl-(2
\rightarrow 1)-\beta-glucopyranoside,
1-O-caffeoyl-\beta-D-apiofuranosyl-(1
\rightarrow 6)-\beta-D-glucopyranoside,
1-O-p-hydroxybenzoyl-\beta-D-apiofuranosyl-(1
\rightarrow 6)-\beta-D-glucopyranoside,
1-O-(3-methyl-2,3,4-trihydroxybutyl)-6-O-feruloyl-\beta-D-glucopyranoside,
4-hydroxyacetophenone
4-O-[5-O-(3,5-dimethoxy-4-hydroxybenzoyl)-\beta-D-apiofrunosyl]-(1
\rightarrow 2)-\beta-D-glucopyranoside
and
1-O-[2-hydroxy-5-(2-hydroxyethyl)phenyl]-6-O-trans-caffeoyl-\beta-D-glucopyranoside.
