Effect of Different Extracts and Monomers of Lepidium meyenii on Proliferation of Mouse Splenic Lymphocyte and Induction of IL-2 and TNF-α
To explore effects of different extracts and monomers of
Lepidium meyenii
(Maca) on the proliferation of mouse splenic lymphocytes and induction of interleukin-2 (IL-2) and tumor necrosis factor-
α
(TNF-
α
) by observing their immunomodulatory effects.
Method
2
An octadecylsilyl (ODS) column was used to enrich the methanol extract of
L. meyenii
in stages to obtain six fractions and three monomers. Different groups of extracts and monomers of
L. meyenii
at different doses were set up. Cell counting Kit-8 (CCK-8) was used to detect the effect on the proliferation of mitogen-free, concanavalin A (Con A)-induced, and lipopolysaccharides (LPS)-induced mouse splenic lymphocytes. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of IL-2 and TNF-
α
.
Result
2
L. meyenii
extracts Fr
3
and Fr
6
, and monomers
N
-benzyl hexadecanamide and 1,2-dihydro-4-carboxaldehyde-3-benzyl-
N
-hydroxypyridine slightly promoted the proliferation of Con A-induced T lymphocytes and LPS-induced B lymphocytes (
P
<
0.01) as compared with the conditions in the model group.
L. meyenii
extracts and monomers significantly induced the secretion of IL-2 and TNF-
α
by splenic lymphocytes (
P
<
0.01).
Conclusion
2
L. meyenii
extracts and monomers can achieve immunological enhancement by promoting the secretion of IL-2 and TNF-
α
, and facilitate the proliferation of splenic lymphocytes. The active components are presumedly macamides and pyridine alkaloids, and the specific mechanism still needs to be further explored.
