Abstract

OBJECTIVE

To study the chemical constituents of the n-BuOH fraction of 95% ethanolic extract of leaves of Neoalsomitra integrifoliola.

METHOD

The compounds were isolated with kinds of column chromatography. The structures were determined by MS and NMR spectroscopic techniques.

RESULT

Eight compounds were isolated from the n-BuOH fraction of 95% ethanolic extract and their structures were identified as 2-phenylethyl rutinoside (1), rutin (2), kaempferol-3-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (3), isorhamnetin-3-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (4), methyl chlorogenate (5), guanosine (6), adenosine (7), myo-inositol (8), respectively.

CONCLUSION

All compounds were isolated from this genus for the first time.
