  • Title: Profiling of components and validated determination of iridoids in Gardenia Jasminoides Ellis fruit by a high-performance-thin-layer- chromatography/mass spectrometry approach.

    Journal: J Chromatogr A; 2014 Jan 17; 1325():221-6. PubMed ID: 24365117.
    Abstract:
    A novel method was set up with the aim to obtain a simultaneous cross comparative evaluation of different Gardenia Jasminoides Ellis fruits by the HPTLC fingerprint approach. The main components among the iridoid, hydroxycinnamic derivative and crocin classes were identified by TLC-MS ancillary techniques. The iridoids geniposide, gardenoside and genepin-1-β-d-gentiobioside were also quantitated by densitometric scanning at 240nm. LiChrospher HPTLC Silica gel 60 RP-18 W F254, 20cm×10cm plates with acetonitrile: formic acid 0.1% (40:60 v/v) as the mobile phase was used. The method was validated giving rise to a dependable and high throughput procedure well suited to routine applications. Iridoids were quantified in the range of 240-1140ng with RSD of repeatability and intermediate precision between 0.9-2.5% and accuracy with bias 1.6-2.6%. The method was tested on six commercial Gardenia Jasminoides fruit samples.
