Asidi wa Vanillic CAS 121-34-6
Asidi ya Vanillic ndi kristalo yoyera ya acicular, yopanda fungo, imatha kusungunuka, siiwola. Malo osungunuka 210℃. Imasungunuka mu ethanol, imasungunuka mu ether, imasungunuka pang'ono m'madzi. Siiwonetsa mtundu ikagwiritsidwa ntchito ndi ferric chloride. Oxalic acid ndi imodzi mwa zigawo zothandiza za Coptis chinensis. Kapangidwe ka coptis officinalis kali ndi vanillic acid, ferulic acid ndi cinnamyl group motsatana, zomwe ndi vanillic acid, ferulic acid ndi cinnamic acid pambuyo pa hydrolysis. Vanillic acid ndi imodzi mwa zigawo za Coptis officinalis zotsutsana ndi mabakiteriya. Kuzindikira kuchuluka kwa vanillic acid kungagwiritsidwe ntchito ngati chizindikiro choyezera mtundu wa Coptis officinalis.
