LC-MS/MS determination of bakkenolide D in rats plasma and its application in pharmacokinetic studies.[Pubmed:23723093]
Biomed Chromatogr. 2013 Sep;27(9):1200-7.
A sensitive and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for determination of Bakkenolide D (BD), which was further applied to assess the pharmacokinetics of BD. In the LC-MS/MS method, the multiple reaction monitoring mode was used and columbianadin was chosen as internal standard. The method was validated over the range of 1-800 ng/mL with a determination coefficient >0.999. The lower limit of quantification was 1 ng/mL in plasma. The intra- and inter-day accuracies for BD were 91-113 and 100-104%, respectively, and the inter-day precision was <15%. After a single oral dose of 10 mg/kg of BD, the mean peak plasma concentration of BD was 10.1 +/- 9.8 ng/mL at 2 h. The area under the plasma concentration-time curve (AUC0-24 h ) was 72.1 +/- 8.59 h ng/mL, and the elimination half-life (T1/2 ) was 11.8 +/- 1.9 h. In case of intravenous administration of BD at a dosage of 1 mg/kg, the AUC0-24 h was 281 +/- 98.4 hng/mL, and the T1/2 was 8.79 +/- 0.63 h. Based on these results, the oral bioavailability of BD in rats at 10 mg/kg is 2.57%.
Anti-allergic effects of total bakkenolides from Petasites tricholobus in ovalbumin-sensitized rats.[Pubmed:20625987]
Phytother Res. 2011 Jan;25(1):116-21.
The anti-allergic effect of total bakkenolides from the rhizome of Petasites tricholobus (BAPT) was evaluated in an ovalbumin-induced allergic rhinitis model in male Wistar rats. The major components of the bakkenolide fraction are bakkenolide-D, bakkenolide-B, bakkenolide-IIIa and bakkenolide-IVa, which account for 60.04% of the total. The rats were treated with 40 mg/kg, 20 mg/kg, 10 mg/kg or 5 mg/kg BAPT, and 0.942 mg/kg loratadine and 0.5% gum tragacanth were used as positive and negative controls, respectively. The frequency of nose rubbing and sneezing was observed, the number of eosinophils infiltrating into the nasal tissue was counted, and serum levels of IL-4 and histamine were determined by ELISA. The results showed that BAPT had a beneficial effect on allergic rhinitis in ovalbumin-sensitized Wistar rats, which was evidenced by a significant decrease in the frequency of sneezing, the number of eosinophils infiltrating into the nasal tissue, and the serum levels of IL-4 and histamine. BAPT may therefore be a potential antiallergic drug.
