• Purification of isolated compounds using chromatographic techniques.
• Structure elucidation using Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) spectral analyses.

Main Results:

• Two phenylpropanoid glucosides, 4-O-methyl guaiacylglycerol 9-O-beta-glucopyranoside (1) and 4-O-methyl guaiacylglycerol 8-O-beta-glucopyranoside (2), were isolated.
• Other compounds including syringin, benzyl alcohol glucoside, isorhamnetin-3-O-beta-glucopyranoside-7-O-alpha-rhamnopyranoside, and quercetin-3-O-beta-glucopyranoside-7-O-alpha-rhamnopyranoside were also identified.
• The structures of all isolated compounds were successfully determined through comprehensive MS and NMR analyses.

Conclusions:

• The aerial parts of Chrozophora obliqua are a source of unique phenylpropanoid glucosides.
• The identified compounds contribute to the phytochemical knowledge of the Chrozophora genus.
• Further studies are warranted to explore the potential biological activities of these isolated natural products.
