Two new cucurbitane-type triterpenoid saponins, 2,20,22-trihydroxy-16,23()-epoxycucurbita-1,5,24-triene-3,11-dione 2---D-glucopyranoside (), 2,20,22-trihydroxy-16,23()-epoxycucurbita-1,5,11,24-tetraene-3-one 2---D-glucopyranoside () were isolated from the fruit of (L.) Schrad. Their structures were elucidated by mass spectrometry, IR, 1D, and 2D NMR spectroscopy, etc. Besides, both of the compounds showed significant hepatoprotective activities at 10 M against paracetamol-induced HepG2 cell damage.

Article Synopsis
- The Cucurbitaceae family, known for its bioactive compounds, is being studied for its potential in preventing and treating colorectal cancer (CRC).
- Four different extracts from cucurbit leaves and seeds were tested on various CRC cell lines to evaluate their effects on tumor growth and cell health.
- Cold ethanolic extracts showed significant anti-cancer properties, such as inhibiting cell proliferation and angiogenesis, and were linked to specific cell cycle changes and gene expression modifications, suggesting they could enhance CRC treatment strategies.
