Anti-angiogenesis properties of Crocus pallasii subsp. haussknechtii, a popular ethnic food

Background and objectives: Angiogenesis is essential for tumor survival. Inhibiting angiogenesis could be a mechanism for hindering tumor development. Numerous studies have now been focused on agiogenesis inhibitors and many of such studies have targeted plant materials. In the present study, Crocus pallasii subsp. haussknechtii has been evaluated for anti-angiogenesis properties. Methods: Anti-angiogenesis activity of the plant extracts and fractions has been investigated through wound healing assay in HUV-EC-C cells. The cytotoxic activity has also been evaluated by MTT assay. Results: The methanol extract and the methanol fraction of the corm along with the chloroform fraction of the aerial parts demonstrated to be cytotoxic to HUV-EC-C cells with IC50 values of 27.2, 74.1 and 60.0 μg/mL, respectively while the chloroform fraction of the corm showed the most considerable anti-angiogenesis property among the samples in wound healing assay. Conclusion: Regarding the results of the present study, Crocus pallasii subsp. haussknechtii is suggested for further studies in cancer research evaluations.
