Objective:
The study was conducted to develop and validate a high performance thin-layer chromatography (HPTLC)-densitometric method for the quantitative analysis of morin in Maclura cochinchinensis heartwood collected from different locations in Thailand.
Methods:
HPTLC analysis was performed on an aluminium sheet of silica gel 60 F254 using toluene: ethyl acetate: formic acid (36:12:7, volume percent) as a mobile phase. The densitometric scanning was performed at the wavelength 410 nm. HPTLC method was validated according to ICH guideline.
Results:
The proposed HPTLC method showed acceptable validation parameters. The content of morin in M. cochinchinensis heartwood collected from eight different provinces in Thailand were in the ranges of 1.53%-2.73%.
Conclusion:
The simple and sensitive HPTLC method was successfully developed and validated for determination of morin in M. cochinchinensis heartwood. The proposed HPTLC method was found to be simple, fast and inexpensive, and can be used for the routine quality control of raw materials.
