Objective:To study chemical constituents of Mosla chinensis'jiangxiangru'.Method:Silica gel column chromatography

Sephadex LH-20 gel column chromatography and MPLC were employed for the isolation and purification.The structures were identified on the basis of spectral data and chemical methods.'Result:'Twelve compounds were identified as follows:β-D-Glucopyranosyl indole-3-carboxylic acid (1)

carvacrol(2)

thymoquinol-2-O-β-glucopyranoside(3)

thymoquinol-5-O-β-glucopyranoside(4)

thymoquinol-2

5-O-β- diglucopyranoside(5)

luteolin(6)

negletein(7)

syringic acid(8)

p-hydroxybenzoic acid(9)

dibutyl terephthalte(10)

oleanolic acid(11)

β-sitosterol(12). Conclusion:these compounds were isolated for the first time from Mosla chinensis[WTBZ] 'jiangxiangru'. Among them

3-carboxyindole-β-glucopyranosid

thymoquinol-2-O-β-glucopyranoside

thymoquinol-5-O-β-glucopyranoside

thymoquinol-2

5-O-β-diglucopyranoside have not been previously described in genus Mosla .
