| Popis: |
The genus Cryptostegia comprises two species, C. madagascariensis (Bojer) and C. grandiflora (Roxb. Ex R. Br) that belong to the Apocynaceae family and are widely distributed in the tropics, as in Australia, New Zealand, India and Brazil, where they cause great socioeconomic and environmental damage, as they are invaders causing damage, mainly in the cultivation of carnaúba, a native plant of great importance in the wax and derivatives industry in Northeast Brazil. Both are perennial shrubs, native to the island of Madagascar, have abundant latex and are known as rubber vine. The plants have the potential for pharmacological, biological and industrial applications. This is due to a rich source of chemical compounds (proteins, phenols, flavonoids, steroids, triterpenoids, cardiac glycosides, etc.) resulting from primary and secondary metabolism. The plants of the Cryptostegia genus showed many activities against bacteria, fungi, insects, Ae. aegypti larvae, Shistosoma sp., as well as for human health as analgesic, anti-inflammatory, antioxidant and antitumoral, and for industrial purposes acting as fibrinogenolytic, hydrolytic, anticorrosive, coagulant and depilatory for leather. Nevertheless, the toxicity is a limitation for the plant use then in order to stand out the economic potential a detailed research on toxicity and management of growing conditions is necessary. |
