Article 1,3-Benzothiazole–oxalic acid (2/1)
It is an excellent work. In our study, we noticed the ability of oxalic acid to form co-crystals with cholesterol and also with sodium ions. Oxalic acid is found in many medicinal plants. But the question is that What is ithe role of oxalic acid to co- precipitate many phytochemicals , especially terpinoids/ steroids/ alkaloids. phenolics or even flavonoid compounds that may have emmense pharmaceutical relevance.Generally we Botanists consider it as an excretary product. But I firmly believe that the oxalic acid in oxalidacea, Aracea etc has a crucial role to release pharmaceutically relavant phytochemicals slowly to the biosystem. In otherwards it also has a chelating property to bind certain metal ions (Na + etc) and in excess concentration may lead to form calcium oxalate.
There is a possibility to form co-crystals with cholesterol but with sodium it is just a salt being formed during acid base reactions!
