[Study on antitumor effect of wutousan]

Area of Science:

• Pharmacology
• Natural Products Research
• Oncology

Background:

• Traditional Chinese medicines (TCMs) are increasingly investigated for therapeutic potential.
• Aconiti Radix and Phellodendri Chinensis Cortex are commonly used TCMs with diverse pharmacological properties.
• Understanding the cytotoxic effects of TCM extracts is crucial for developing novel anticancer agents.

Purpose of the Study:

• To screen and identify active extracts from selected traditional Chinese medicines.
• To evaluate the in vitro antiproliferative effects of these extracts on various cancer cell lines.

Main Methods:

• Extraction of Unprocessed Aconiti Radix, Aconiti Radix Cocta, and Phellodendri Chinensis Cortex using 70% alcohol and water.
• Assessment of cell proliferation using the MTT assay.
• Testing on human cancer cell lines: SMMC7721, MCF7, A549, Hela, and SGC7901.

Main Results:

• 70% alcohol extracts of Unprocessed Aconiti Radix, Aconiti Radix Cocta, and Phellodendri Chinensis Cortex exhibited significant, dose-dependent inhibition of A549 and Hela cell proliferation.
• Water extract of Phellodendri Chinensis Cortex also showed inhibitory effects on A549 and Hela cells.

Conclusions:

• Alcohol extracts of Unprocessed Aconiti Radix, Aconiti Radix Cocta, and Phellodendri Chinensis Cortex possess notable cytotoxic activity against A549 and Hela cancer cells.
• The water extract of Phellodendri Chinensis Cortex demonstrated inhibitory effects on these cell lines.
• A synergistic antiproliferative effect was observed when Aconiti Radix and Phellodendri Chinensis Cortex were combined against Hela cells.
