目的
2
探讨柴胡皂苷类成分的肠吸收特性。
方法
2
基于大鼠外翻肠囊模型,以累积吸收量(
Q
)、吸收速率常数(
K
a
)为指标,以超高效液相色谱-串联质谱技术为手段,检测柴胡总皂苷提取液(8 g/mL,以生药量计)中柴胡皂苷A、B
2
、C、D、F在十二指肠、空肠、回肠中的吸收情况。
结果
2
柴胡皂苷A、B
2
、C、F在十二指肠、空肠、回肠中吸收回归方程的相关系数(
r
)均大于0.95,柴胡皂苷D在上述肠段中的
r
均小于0.95;与同成分在十二指肠中的吸收比较,柴胡皂苷A、C在空肠、回肠中循环120 min时的
Q
、
K
a
以及柴胡皂苷F在回肠中循环120 min时的
Q
、
K
a
均显著降低(
P
<0.05)。
结论
2
柴胡皂苷A等5种柴胡皂苷类成分在十二指肠、空肠、回肠中均有吸收,其中柴胡皂苷A、B
2
、C、F均为线性吸收,符合零级吸收特征;柴胡皂苷D为非线性吸收。
OBJECTIVE
2
To explore the intestinal absorption characteristics of saikosaponins.
METHODS
2
Based on everted intestinal sac model, using accumulative absorption
amount (
Q
) and absorption rate constant (
K
a
) as indexes, UHPLC-MS/MS technique as a method, the absorption of saikosaponin A, B
2
, C, D and F from total saponins of
Bupleurum chinense
(8 g/mL, by crude drug) in the duodenum, jejunum and ileum was detected.
RESULTS
2
The correlation coefficients (
r
) of the regression equations for the absorption of saikosaponins A, B
2
, C and F in the duodenum, jejunum and ileum were all higher than 0.95, while the
r
of saikosaponin D in the above intestinal segments was lower than 0.95; compared with the absorption of the same composition in the duodenum, the
Q
and
K
a
of saikosaponin A and C circulating in jejunum and ileum for 120 min, as well as the
Q
and
K
a
of saikosaponin F circulating in the ileum for 120 min were significantly decreased (
P
<0.05).
CONCLUSIONS
2
Saikosaponin A and the other 4 saikosaponins are all absorbed in the duodenum, jejunum and ileum; among them, saikosaponin A, B
2
, C and F are linearly absorbed, which conforms to the zero-order absorption characteristics, but saikosaponin D shows non-linear absorption.
