CBS 86, 13-15 (2001). HPTLC on silica gel (prewashed with methanol) with THF - toluene - formic acid - water 16:8:2:1 for flavonoids and toluene - ethyl acetate 9:2 for diterpenes. Detection of flavonoids by dipping in natural products reagent followed by dipping in PEG 6000 solution. Detection of diterpenes by dipping in anisaldehyde reagent. Evaluation with video technology.
Indian Drugs 41 (1), 46-47, 2004. HPTLC on silica gel plates with n-propanol - formic acid - water 90:1:9. Rf of berberine was 0.39. Quantification by densitometry at 348 nm via linear regression in the range of 40-220 ng. Limit of quantification and limit of detection were found to be 30 ng and 10 ng, respectively. The herbal extract was found to contain 0.402 % w/w of berberine. The percentage of berberine in formulations I, II, III and IV were 0.0886 %, 0.0123 %, 0.0283 % and 0.0091 % w/w, respectively. The standardized method was found to be reproducible, accurate, precise and selective.
