Key Findings

  • Researchers at The University of Jordan found that ginger extracts have strong anticancer effects on colorectal cancer cells
  • Ginger extracts, especially those with high quercetin content, significantly inhibited the growth of HT-29 colorectal cancer cells
  • The study supports ginger's potential as a natural treatment for colorectal cancer due to its rich flavonoid and phenolic content
Colorectal cancer (CRC) is the fourth leading cause of death from malignant tumors, emphasizing the urgent need for more effective treatments. Recent research conducted at The University of Jordan explored the potential anticancer properties of Zingiber officinale, commonly known as ginger, which is believed to possess significant anticancer properties due to its rich content of flavonoids and phenols[1]. The study aimed to evaluate the amounts of specific bioactive compounds—quercetin, gallic acid, rutin, naringin, and caffeic acid—in ginger capsules using Soxhlet (SOXT) and maceration (MACR) extraction techniques. High-performance liquid chromatography (HPLC) paired with ultraviolet detection was employed for the separation and quantitation of these compounds. Additionally, the study assessed the in vitro toxicity of ginger capsules on the HT-29 colorectal adenocarcinoma cell line to determine their anticancer efficacy. The findings revealed that ginger herbal supplement extracts, at dosages of 200 and 100 μg, exhibited strong cytotoxic effects on HT-29 CRC cells, with IC50 values (the concentration required to inhibit cell growth by 50%) of less than 50 μg/mL for both MACR and SOXT extracts. Notably, the quercetin content was the highest among the extracts, as indicated by the HPLC data. These results align with previous studies highlighting the anticancer potential of ginger. For instance, an earlier study demonstrated that ethanolic ginger extract (GE) had significant antiproliferative activity against HCT-116 colon cells and could induce apoptosis through both extrinsic and intrinsic pathways[2]. The study also showed that GE could alleviate the harmful effects of dimethylhydrazine (DMH)-induced colorectal tumors in rats more effectively and safely than cisplatin, a commonly used chemotherapy drug[2]. The antioxidant properties of ginger, which contribute to its anticancer effects, have also been well-documented. Research on the phytochemical profile and antioxidant activity of ginger and garlic in Uganda found that ginger extracts, particularly those obtained using ethanol, exhibited high total phenolic and flavonoid content, which correlated strongly with their free radical scavenging activity[3]. These antioxidant properties are crucial as they help neutralize free radicals, potentially reducing cancer risk. Moreover, the current study's findings are consistent with the observed cytotoxic and apoptotic properties of ginger essential oils on colorectal cancer cell lines. Previous research demonstrated that ginger essential oil had one of the lowest IC50 values among various tested essential oils, indicating strong cytotoxic activity against HT-29 cell lines[4]. This further supports the potential of ginger as a natural anticancer agent. In summary, the study conducted at The University of Jordan underscores the significant anticancer activity of ginger herbal supplements against CRC. Both the MACR and SOXT extraction methods yielded potent extracts with high quercetin content, which exhibited strong cytotoxic effects on HT-29 CRC cells. These findings, together with earlier research, suggest that ginger's rich flavonoid and phenolic content contribute to its efficacy as a natural anticancer agent. This research paves the way for the development of novel, more effective treatments for colorectal cancer, leveraging the bioactive compounds in ginger.
