  • Title: Quantitative analysis of tiliroside and other flavonoid glycosides in Hippophae salicifolia D. Don leaves by HPLC-PDA.

    Journal: Nat Prod Res; 2024 Apr; 38(8):1445-1450. PubMed ID: 36445311.
    Abstract:
    A new HPLC-PDA method was developed and validated for simultaneous determination of five phenolic compounds (trans-and cis- isomers of tiliroside, quercetin-3-O-β-D-glucoside, ellagic acid, kaempferol-3-O-β-D-glucoside and isorhamnetin-3-O-glucoside) in the leaves of Hippophae salicifolia D. Don. Of the five compounds, three (tiliroside, quercetin-3-O-β-D-glucoside and ellagic acid) were isolated and characterised by spectroscopy techniques. The developed HPLC method provided a selective, sensitive and rapid analysis with good linearity (r2> 0.999), accuracy and precision. Also, the leaves of H. salicifolia were extracted by three different extraction techniques viz. reflux, microwave and ultrasound. Methanolic extracts prepared by reflux method showed the highest content of all the five compounds.
