Direct in vitro regeneration of Curculigo orchioides Gaertn., an endangered anticarcinogenic herb

摘要

Curculigo orchioides is an endangered medicinal herb belonging to the family Amayrllidaceae. The rhizome extract shows hypoglycemic, spasmolytic and anticancer activities. Its anticarcinogenic activity was observed against Sarcoma-180 in mouse. The tuberous roots are valued in both Indian and Chinese herbal remedies, and used as a tonic for health, vigour and vitality due to the presence of flavnone glycosides. The powdered rhizome applied to cuts is said to stop bleeding and dry up wounds. This monocotyledonous herb is popularly known as 'Kali Musli' in this part of the subcontinent. The total produce per year varies from 400 to 500 g per plant and the cost of produce is around Rs 200 per kg of root. Due to its significant medicinal properties, C. orchioides has been overexploited, which in turn has led to its inclusion in the list of threatened plant species.
