Water-soluble phenolic glycosides from the whole plant of Bulbophyllum odoratissimum.
OBJECTIVE
To investigate the water-soluble phenolic glycosides from the whole plant of Bulbophyllum odoratissimum.


METHODS
Column chromatography techniques were used to isolate the chemical constituents, physico-chemical constants and spectroscopic analysis were employed for structural elucidation.


RESULTS
Bulbophyllinoside (1), a new phenolic glycoside and three known compounds were isolated from the whole plant of Bulbophyllum odoratissimum Lindl. Their structures were determined as 3-hydroxyphenethyl alcohol 4-O-( 6'-O-beta-apiofuranosyl) -beta-D-glucopyranoside (1), 3-methoxyphenethyl alcohol 4-O-beta-D-glucopynanoside (2), 3, 5-dimethoxyphenethyl alcohol 4-O-alpha-D-glucopynanoside (3) and syringin (4).


CONCLUSIONS
Bulbophyllinoside (1) is a new compound.
