Production of paeoniflorin and albiflorin by callus tissue culture of Paeonia lactiflora Pall
摘要
Abstract
In order to facilitate the preparation of paeoniflorin (PF) and albiflorin (AF)
two chief bioactive constituents in
Paeonia lactiflora
Pall (PL)
induction and culture of callus from PL were studied. With a modified woody plant medium supplemented with 0.5 mg·L
-1
6-benzylaminopurine
1.0 mg·L
-1
naphthylacetic acid
0.1 mg·L
-1
thidiazuron and 30 g·L
-1
sucrose
callus was induced from four kinds of explants: leaf
stems
petiole
and root. The potency to formcallus varies between different explants and leaf explants exhibits the highest capacity (100%). On the other hand
root-derived callus (R-callus) produces the highest level of total amount of PF and AF
31.8 mg·g
-1
dry mass
which is higher than the corresponding level in the root of field cultivated PL. Furthermore
the timeneeded is only 40 days
remarkably shorter than the cultivation timeof PL
about 4-5years. Higher accumulation levels of PF and AF with shorter production time indicate that callus culture of PL is a promising powerful tool for production of PF and AF in the future.
