OBJECTIVE
The anticancer activity of shatavarins (containing shatavarin IV) isolated from the roots of Asparagus racemosus (Wild) was evaluated using in vitro and in vivo experimental models.
METHODS
The shatavarin IV was isolated from ethyl acetate insoluble fraction (AR-2B) of chloroform:methanol (2:1) (AR-2) extract of A. racemosus roots. The cytotoxicity (in vitro) of shatavarin IV and other shatavarins rich fraction was carried out using of MTT assay using MCF-7 (human breast cancer), HT-29 (human colon adenocarcinoma), and A-498 (human kidney carcinoma) cell lines. The in vivo anticancer activity of shatavarins (containing shatavarin IV) was evaluated against Ehrlich ascites carcinoma (EAC) tumor bearing mice.
RESULTS
The isolated shatavarin IV (84.69 %) along with shatavarins rich fraction, coded AR-2B containing 5.05% shatavarin IV showed potent cytotoxicity. Oral administration of AR-2B to tumor bearing mice at doses of 250 and 500 mg/kg body weight for 10 days, showed significant reduction in percent increase in body weight, tumor volume, packed cell volume, viable tumor cell count, and increased non-viable cell count when compared to the untreated mice of the EAC control group. The restoration of hematological parameters towards normalcy was also observed.
CONCLUSIONS
The result suggests that the shatavarins (containing shatavarin IV) rich fraction (AR-2B) exhibits significant anticancer activity in both in vitro and in vivo experimental models.
