Study on characteristic chromatogram of Yao medicine Kadsura longipedunculata and its anwulignan content and anti-inflammatory activity
To establish characteristic chromatogram of Yao medicine
Kadsura longipedunculata
and the method for the content determination of its main component anwulignan, and evaluate the anti-inflammatory activity of anwulignan.
METHODS
2
HPLC method was performed with acetonitrile-0.5% phosphoric acid solution as the mobile phase for gradient elution. The characteristic chromatogram of
K. longipedunculata
was established and similarity was evaluated by
Similarity Evaluation System for Chromatographic Fingerprint of TCM
(
2012 edition
). The content of anwulignan in
K. longipedunculata
was determined. Lipopolysaccharide induced RAW264.7 macrophages were selected as inflammatory cell model to investigate the effects of anwulignan on the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6.
RESULTS
2
The similarities of characteristic chromatogram for 10 batches of
K. longipedunculata
ranged 0.901-0.994, and 9 common peaks were determined; 3 components were identified, such as changnan schisantherin E, kadsulactone A, anwulignan. The contents of anwulignan were (0.72±0.05)-(1.21±0.03) mg/g(
n
=3). Anwulignan of 0.125-0.5 μg/mL greatly decreased the levels of TNF-α, IL-1β and IL-6 in the supernatant of inflammatory model cells (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
HPLC characteristic chromatogram of
K. longipedunculata
and the method for the content determination of anwulignan are all established, and anwulignan may be the active ingredient of anti-inflammatory effect in
