Lycium halimifolium leaves contain five flavonol glycosides and two genins, including quercetin and kaempferol derivatives. These compounds were identified using hydrolysis and spectral analysis, contributing to phytochemical knowledge.

Area of Science:

  • Phytochemistry
  • Natural Product Chemistry

Background:

  • Lycium halimifolium (Solanaceae) is a plant species with potential medicinal properties.
  • Flavonoids, particularly flavonol glycosides and genins, are known for their diverse biological activities.

Purpose of the Study:

  • To isolate and identify the chemical constituents from the leaves of Lycium halimifolium.
  • To characterize the identified flavonol glycosides and genins.

Main Methods:

  • Extraction of compounds from Lycium halimifolium leaves.
  • Acid and enzymatic hydrolysis for structural elucidation.
  • Spectroscopic data analysis (e.g., NMR, MS) for compound identification.

Main Results:

  • Isolation of five flavonol glycosides: quercetin 3-O-rutinoside-7-O-glucoside, kaempferol 3-O-rutinoside-7-O-glucoside, rutin, nicotiflorin, and isoquercitrin.

  • Isolation of two genins: quercetin and kaempferol.
  • Confirmation of compound structures through hydrolysis and spectral data.

    • Conclusions:

    • The phytochemical profile of Lycium halimifolium leaves is rich in various flavonol glycosides and their corresponding genins.
    • The identified compounds contribute to the understanding of the chemical diversity within the Solanaceae family.
