What medicinal compounds this plant contains?
This plant contains several medicinal compounds including patuletin 3-O-(4''-O-acetyl-α-L-rhamnopyranosyl)-7-O-(3'''-O-acetyl-α-L-rhamnopyranoside), patuletin 3-O-α-L-rhamnopyranosyl-7-O-L-rhamnopyranoside, polyphenols, sterols, and triterpenes. These diverse chemical constituents contribute to the biological activities observed in Kalanchoe crenata. The presence of specific glycosylated flavonoids like the patuletin derivatives suggests potential antioxidant properties. Furthermore, the concentration of sterols and triterpenes provides a complex structural foundation for its therapeutic profile. These various organic molecules work together to define the plant's medicinal potential.
According to a study published by "Molecules (Basel, Switzerland)", the aqueous extract of Kalanchoe crenata contains specific chemical markers. The main compounds identified in the extract are patuletin 3-O-(4''-O-acetyl-α-L-rhamnopyranosyl)-7-O-(3'''-O-acetyl-α-L-rhamnopyranoside) (1) and patuletin 3-O-α-L-rhamnopyranosyl-7-O-L-rhamnopyranoside (2). Additionally, the extract contains trans-caffeoyl-malic acid (3). Compounds 1 and 2 serve as the chemical markers for this species. The study utilized 6 groups of 10 animals each to investigate these effects.

What health conditions is this plant used for?
This plant is used for treating adriamycin-induced renal impairment, kidney dysfunction, nephropathy, glucosuria, and proteinuria. Research suggests that extracts from Kalanchoe crenata may offer protective effects against damage caused by chemotherapy agents. These bioactive compounds help mitigate the severity of nephropathy by stabilizing kidney function. The plant's properties are also studied for their ability to reduce proteinuria and manage glucosuria in compromised subjects. Through these mechanisms, it serves as a potential therapeutic agent for various forms of kidney dysfunction.
According to a study published by "Indian journal of pharmacology", the methanolic fraction of Kalanchoe crenata was used to treat adriamycin-induced renal impairment in rats. After receiving three intravenous injections of 2 mg/kg body weight of adriamycin, rats were treated with doses of 0, 50, and 68 mg/kg b.w. of the extract for 6 weeks. The K. crenata extract significantly decreased proteinuria and the urinary excretion of creatinine, glucose, and urea. It also decreased serum levels of creatinine, urea, potassium, alkaline phosphatase, conjugate bilirubin, and alanine transaminase, while increasing plasma sodium (P < 0.05) and decreasing urinary sodium and potassium (P < 0.01). These results suggest that K. crenata may improve proteinuria and symptoms of nephropathy while potentially ameliorating kidney and liver functions better than 10 mg/kg b.w. of losartan.
