Ib nrab hauv nruab nrab rau kev ua siab phem li cas los. Nws tseem yog qhov nruab nrab ntawm kev kuaj mob tshuaj wbiquitin tshiab (xhoo ray sib piv tus neeg sawv cev); Nws tseem siv los ua ke los ntawm cov tshuaj tshiab cov tshuaj uas yog PDE IV inhibitor glycolinic acid; Nws kuj yog siv rau hauv nruab nrab rau kev ua siab dub (xiav azo dyes).
Hnov cov txiv lws suav sulfuric acid (104.3ml, 1.92Mol) tau ntxiv rau 60 ℃, tuav tau ntxiv, 40s, 0.36Mol) tau ntxiv los tswj cov degret nrawm. Ntxiv nws hauv 2 teev. Tom qab ntxiv, tiv thaiv kom sov kom tiv thaiv thaum 60 ℃ rau 2 teev. Txias rau hauv qab no 50 ° C, tom qab ntawd ntxiv 100ml ntawm dej. Cov khoom siv tau txias rau chav sov, nchuav rau cov khib nyiab, ua kom cov roj ntsha tau ntxuav, thiab cov khoom siv lim dej yog 34.6 grams, cov txiaj ntsig yog 68.4%.
