[Glycosides from Periploca forrestii]

Area of Science:

• Phytochemistry
• Natural Product Chemistry
• Pharmacognosy

Context:

• Periploca forrestii is a plant species with potential medicinal applications.
• Understanding the chemical constituents of medicinal plants is crucial for drug discovery and development.
• Previous phytochemical investigations of Periploca forrestii may have been limited.

Purpose:

• To isolate and identify chemical constituents from the n-BuOH fraction of Periploca forrestii stems.
• To characterize the structure of the isolated compounds using physico-chemical properties and spectral data.

Summary:

• Six glycosides were successfully isolated and identified from the n-BuOH fraction of Periploca forrestii stems.
• The identified compounds include emodin-8-O-beta-D-glucopyranoside, physcion-8-O-beta-D-glucopyranoside, kaempferol-3-O-beta-D-galactopyranoside, kaempferol-3-O-alpha-L-arabinopyranoside, quercetin-3-O-beta-D-glucopyranoside, and quercetin-3-O-alpha-L-arabinopyranoside.
• These six glycosides represent novel findings, being reported from this plant for the first time.

Impact:

• Establishes a foundational phytochemical profile for Periploca forrestii, specifically regarding its glycosidic constituents.
• Provides valuable data for researchers interested in the ethnopharmacology and potential therapeutic uses of Periploca forrestii.
• Contributes to the broader knowledge base of natural product chemistry and the diversity of plant secondary metabolites.
