Stems thiab nplooj muaj triterpenes, malic acid thiab succinic acid. Tshauv muaj 24 feem pua poov tshuaj carbonate.
1. Cov nyhuv poob: cactus muaj cov khoom hu ua propanedioic acid, uas tuaj yeem cuam tshuam kev loj hlob ntawm cov rog; cactus muaj triterpenoid saponins, triterpenes yog cov khoom tseem ceeb rau tib neeg lub cev, lawv tuaj yeem ncaj qha tswj kev ua haujlwm ntawm tib neeg lub cev thiab tswj cov rog Cov kev ua haujlwm ntawm cov enzymes txhawb kev tawg sai ntawm cov rog dhau, thiab tuaj yeem tiv thaiv kev nqus ntawm cov rog hauv lub cev. plab hnyuv, inhibit synthesis ntawm cov rog nyob rau hauv lub siab, tiv thaiv cov deposition ntawm cov cholesterol nyob rau hauv lub puab phab ntsa ntawm cov hlab ntsha, thiab maj mam poob phaus. Tsis tsuas yog nws tsis ua kev puas tsuaj tseem ceeb, tab sis hloov kho cov as-ham thiab ua rau tib neeg lub zog; malic acid yog digested thiab plab, thiab tuaj yeem txhawb txoj hnyuv motility, uas muaj kev ua haujlwm ntawm moistening cov hnyuv thiab laxatives.
2. Cov nyhuv hypoglycemic: Cactus muaj ntau yam flavonoids, xws li quercetin-3-glucoside, uas muaj cov nyhuv hypoglycemic pom tseeb thiab tuaj yeem txhim kho cov piam thaj metabolism hauv cov neeg mob ntshav qab zib hom II. Cactus extract muaj cov khoom hu ua propanedioic acid, uas tuaj yeem cuam tshuam kev loj hlob ntawm cov rog. Cactus tseem muaj ntau yam flavonoids, uas muaj cov teebmeem hypoglycemic pom tseeb thiab tuaj yeem txhim kho cov piam thaj metabolism hauv cov neeg mob ntshav qab zib hom II.
3. Antibacterial thiab anti-inflammatory teebmeem: Cactus muaj inhibitory cuam tshuam rau Staphylococcus aureus, Proteus, Escherichia coli, Bacillus subtilis, thiab Bacillus cereus.
