In vitro Anti Inflammatory Activity of Abies webbiana Using Albumin Denaturation Assay

Background: In ayurveda, many natural plant components are used to treat inflammatory conditions for centuries with less side effects. Different parts of Abies webbiana plant are used in ayurveda for many diseases. However, very few studies have been conducted to evaluate pharmacological effects of Abies webbiana.

Aim: The objective of this in vitro study was to analyse and compare the anti-inflammatory properties of A. webbiana at various concentrations using albumin denaturation assay.

Methodology: A ready made powder of A. webbiana was mixed with 100 ml of distilled water and boiled for 10 mins the extract was obtained by filtration. The anti-inflammatory activity was done using albumin denaturation assay and Diclofenac sodium was used as a positive control. Serial dilution from 10 µL, 20 µL, 30 µL, 40 µL and 50 µL was performed for A. webbiana and the reference drug reaction mixture was prepared for albumin denaturation assay. All the data was analysed statistically using SPSS version 23 (IBM). Unpaired t test was used for comparison with the positive control and one-way Anova followed by Tukey’s post hoc test were used for the comparison between different concentrations.

Results: The current study revealed that A. webbiana extract had potent anti-inflammatory activity at all the tested concentrations but was significantly lesser when compared to the standard (p<0.05). It was also evident that the absorbance rate of A. webbiana significantly increased with the increase in concentration of the extract (p<0.05). However, the absorbance rate at 50 µL of both standard and A. webbiana were almost similar.

Conclusion: It can be concluded from the present findings that the leaves of A. webbiana possess concentration-dependent anti-inflammatory property but is comparatively lesser than Diclofenac sodium.
