Aim 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-β-apiofuranosyl)-β-D-glucopyranoside (1), 3-methoxyphenethyl alcohol 4-O-β-D-glucopynanoside (2), 3,5-dimethoxyphenethyl alcohol 4-O-β-D-glucopynanoside (3) and syringin (4). Conclusion Bulbophyllinoside (1) is a new compound.
