What medicinal compounds this plant contains?
This plant contains the medicinal compounds Trichosanthin, alpha-trichosanthin, trichosan A, trichosan B, and trichosan C. These specific chemical constituents are primarily classified as triterpenoid saponins. They are often studied for their significant biological activities, including potential anti-tumor and anti-inflammatory properties. Researchers focus on these molecules to understand how the plant interacts with human cellular processes. The diversity of these compounds contributes to the overall therapeutic profile of the species.
According to a study published by "Current medicinal chemistry", Trichosanthes kirilowii contains the famous type I ribosome inactivating protein known as trichosanthin (TCS), which has been known for around 30 years. This species also produces other promising ribosome inactivating proteins such as TAP29 and trichoanguin. These proteins function as toxic RNA N-glycosidases that cleave an adenine-ribose glycosidic bond at position adenine(4324) with the conserved ricin/α-sarcin loop in the eukaryotic 28S ribosomal RNA. Based on voluminous in vitro and in vivo investigations, TCS is considered a good candidate for the treatment of neoplasms and HIV/AIDS. Out of 145 families of plants, the genus Trichosanthes ranks among the top 5 genera with potential for the discovery of anticancer drugs.

According to a study published by "International journal of peptide and protein research", trichosanthin is a known abortifacient protein isolated from the root tubers of the Chinese drug, Tianhuafen, which comes from Trichosanthes kirilowii. This protein is part of the Cucurbitaceae family. Trichosanthin is used in medicinal preparations but differs from beta-trichosanthin in molecular weight, carbohydrate content, charge, and amino acid composition. While beta-trichosanthin is about twice as potent as trichosanthin in inducing mid-term abortion in mice, the two proteins are immunochemically identical.
The main herbal preparations of this plant are shown in the list below.
- Tianhuafen
- Trichosanthis Fructus
- Methanolic extract
- Aqueous extracts

What side effects this plant can have?
This plant can cause various adverse health effects including abortifacient properties, anti-tumor activities, immunosuppression, mosaic symptoms, and reduced body weight. The presence of abortifacient compounds means that consumption may lead to the loss of a pregnancy. Its anti-tumor mechanisms may interfere with normal cell growth, while its ability to cause immunosuppression weakens the body's natural defenses. Some individuals may experience mosaic symptoms, which manifest as irregular patterns or irregularities in bodily functions or skin. Finally, regular ingestion has been linked to significant reduced body weight in certain subjects.
According to a study published by "Transplantation proceedings", the extract trichosanthin from the root tuber of Trichosanthes kirilowii possesses abortifacient, anti-tumor, anti-HIV, and immunoregulatory functions. In a murine skin transplantation model, treatment of recipient mice with trichosanthin at doses of 0.25 or 1 mg/kg (IP) significantly delayed alloograft rejection. T cells from recipients treated with this extract showed a significantly reduced response when restimulated with donor-specific splenocytes. Following treatment, mRNA levels for interleukin (IL)-2 and interferon-gamma decreased, while levels of IL-4 and IL-10 increased in splenic T cells. These findings suggest that Trichosanthes kirilowii may have therapeutic value for transplantation rejection and other inflammatory diseases.
The main side effects this plant can have are shown in the list below.
- abortifacient
- anti-tumor
- immunosuppression
- mosaic symptoms
- reduced body weight
