According to a study published by "Chemical & pharmaceutical bulletin", thirteen phenolic glycosides, which included six new compounds, were isolated from the seeds of Cassia tora. These new structures identified include rubrofusarin triglucoside (7), nor-rubrofusarin gentiobioside (9), demethylflavasperone gentiobioside (10), torachrysone gentiobioside (11), torachrysone tetraglucoside (12), and torachrysone apioglucoside (13). The antibacterial effects of related compounds such as torachrysone (15), toralactone (16), aloe-emodin (18), rhein (19), and emodin (20) were examined against various bacteria. These specific compounds showed noticeable antibacterial effects on four strains of methicillin-resistant Staphylococcus aureus. The minimum inhibitory concentration for these effects was measured at 2-64 micrograms/ml. However, the phenolic compounds tested did not show strong antibacterial effects on E. coli and P. aeruginosa.

What medicinal compounds this plant contains?
This plant contains the medicinal compounds auraunti-obtusin, chryso-obtusin, emodin, rhein, and physcion. These specific anthraquinones are responsible for the plant's significant biological activities. Many of these chemical constituents function as potent laxatives by stimulating intestinal motility. Additionally, the presence of these compounds contributes to the overall antioxidant and antimicrobial properties of the species. Researchers study these substances to better understand their therapeutic potential in treating various gastrointestinal issues.
According to a study published by "Parasites & vectors", the medicinal leguminous plant Cassia tora L. (Fabaceae) contains key anthraquinones identified as aurauntiio-obtusin and obtusin. These two anthraquinone isolates were identified using liquid chromatography-quadrupole time of flight mass spectrometry (LC-QtoF-MS). The compound aurauntiio-obtusin exhibited an LD50 value of 10 ppm, while obtusin showed an LD50 value of 10.2 ppm against larvae of A. gambiae (s.s.). These specific anthraquinones were four- and ~ six-fold less potent than the crude seed extract, which had an LD50 value of 2.5 ppm. The study also compared these results to azadirachtin, which had an LD50 value of 1.7 ppm.
The primary medicinal compounds of this plant are shown in the list below.
- aurantio-obtusin

What side effects this plant can have?
This plant can cause serious health issues such as DNA strand breaking, constipation, hypotension, laxative effects, and the development of plaque and caries. When consumed excessively, its potent laxative properties can disrupt normal bowel functions and lead to severe constipation if used improperly. The chemical compounds within the plant may also trigger hypotension by causing a dangerous drop in blood pressure. Research suggests that certain components have the potential for cellular damage, specifically through DNA strand breaking. Additionally, regular exposure to its residues may contribute to the formation of dental plaque and caries.
According to a study published by "Journal of agricultural and food chemistry", Cassia tora L. water extracts alone induced a slight strand breaking of DNA. In the presence of Fe(3+)/H(2)O(2), the extract accelerated DNA strand breaking at a concentration of 2 microg/mL, though this decreased at concentrations greater than 5 microg/mL. The extract also accelerated deoxyribose oxidation induced by Fe(3+)-EDTA/H(2)O(2) at a concentration of 0.2 mg/mL. Additionally, Cassia tora L. accelerated the oxidation of 2'-deoxyguanosine to form 8-OH-2'-dG. The prooxidant action on 2'-dG followed an order of unroasted, roasted at 150 degrees C, roasted at 200 degrees C, and roasted at 250 degrees C.
The main side effects this plant can have are shown in the list below.
- DNA strand breaking
- constipation
- hypotension
- laxative
- plaque and caries
