Chemical constituents from Trillium camschatcense

Area of Science:

• Natural Product Chemistry
• Pharmacognosy
• Medicinal Chemistry

Background:

• Trillium camschatcense is a plant species with a history of traditional medicinal use.
• Steroidal saponins and resveratrol derivatives are classes of natural products known for diverse biological activities.

Purpose of the Study:

• To isolate and characterize chemical constituents from the roots and rhizomes of Trillium camschatcense.
• To evaluate the cytotoxic potential of the isolated compounds against the MCF-7 cell line.

Main Methods:

• Extraction of plant material using 70% ethanol.
• Isolation of compounds using chromatographic techniques.
• Structure elucidation through spectroscopic analysis (NMR, MS) and chemical degradation.
• Cytotoxicity assessment using MTT assay against MCF-7 cells.

Main Results:

• Two new polyacetylated 18-norspirostanol saponins (trilliumosides J and 21-deoxyepitrillenoside C) were identified.
• A novel resveratrol aneuploid, 3a,3b-dimethoxyhopeachinol B, was discovered.
• Four known steroidal saponins were also isolated and characterized.
• Compounds 1 (trilliumoside J), 3 (3a,3b-dimethoxyhopeachinol B), and 4 exhibited cytotoxic activity against MCF-7 cells with IC50 values of 86.38 ± 2.59 μM, 56.20 ± 1.57 μM, and 45.70 ± 0.63 μM, respectively.

Conclusions:

• The chemical investigation of Trillium camschatcense yielded novel saponins and a resveratrol derivative.
• Compounds 1, 3, and 4 demonstrate promising cytotoxic effects, warranting further investigation for potential anticancer applications.
