[Alkaloids from cervi cornu pantotrichum and its effect on murine splenocytes proliferation]
Objective:
To study the alkaloids of Cervi Cornu Pantotrichum and its effect on murine splenocytes proliferation.
Methods:
The constituents isolation and purification from Cervi Cornu Pantotrichum was carried out by reported column chromatography including Sephadex LH-20 and MCI (CHP20P) and their structures were elucidated on the basis of spectral compounds. The method of MTT was used to examine the effects of eight alkaloids and total alkaloids content (TAC) of Cervi Cornu Pantotrichum on murine splenocytes proliferation.
Results:
Eleven compounds were isolated from Cervi Cornu Pantotrichum, and their structures were identified as follows: uracil (1), hypoxanthine (2), uridine (3) inosine (4), guanosine (5), 2'-deoxyguanosine (6), guanine (7), thymidine (8), thymine (9), cytidine (10) and adenosine (11). By the experiment of murine splenocytes proliferation activity in vitro, the results showed that the total alkaloids, uracil and adenosine had significantly promoted the proliferation of mouse spleen cells.
Conclusion:
Compounds 4 - 11 are isolated from Cervi Cornu Pantotrichum for the first time. The total alkaloids is one of the material basis of immunomodulatory effects of Cervi Cornu Pantotrichum, and uracil and adenosine are the most active.
