- Abstract: To research the intestinal toxicity of n-BuOH fraction in Phytolacca Radix before and after being processed with vinegar. Toxic n-BuOH fractions were separated from Phytolacca Radix. In the animal model, the level of intestinal edema, water content of intestine and stool, IC₅₀ values of HT-29 and IEC-6 were detected with MTT method to compare the changes in toxicity of n-BuOH fractions from Phytolacca Radix before and after being processed with vinegar. n-BuOH fractions of Phytolacca Radix could cause intestinal edema in mice, increase the edema of duodenum, jejunum and the water content in stool, inhibit the proliferation of HT-29 cells and IEC-6 cells, indicating its intestinal toxicity, with HT-29 IC₅₀ at 14.59 mg•L⁻¹ and IEC-6 IC₅₀ at 43.77 mg•L⁻¹. After being processed with vinegar, the level of intestinal edema, edema of duodenum and jejunum and the water content in stool and inhibition ratio of cells line were reduced, with HT-29 IC₅₀ at 58.51 mg•L⁻¹ and IEC-6 IC₅₀ at 84.37 mg•L⁻¹. After being processed with vinegar, the toxicity of n-BuOH fractions from Phytolacca Radix decreased obviously.
