5a-Rosy Periwinkle, Flashcards
what is the source of morphine
Seed pods of several species of opium poppy
what are the growing conditions for morphine
Warm humid conditions
susceptible to frost and wet weather
what is morphine used for
pain reliever
source of Quinine
Bark of evergreen tree
growing conditions for Quinine
humid conditions with average temp ( 20C)
susceptible to frost
what is quinine used for
kills malaria parasite in blood
what type of plant is the Rosy Periwinkle
small evergreen shrub native to tropical regions eg: Madagascar
what growing conditions are needed for the Rosy Periwinkle
Warm tropical climate
slightly acidic and well drained soils ( but hold moisture)
international trade of Rosy Periwinkle
Commercially grown in tropical regions - Madagascar
sold to Pharmaceutical companies(Eli Lilly) for high amounts of money
why is the rosy periwinkle important in battling disease
contains 70 known alkaloids of significant value:
- Vincristine used in chemotherapy = increased survival rates by 90%
give an example of a strategy used for sustainable growth of the Rosy Periwinkle
Reducing deforestation and the destruction of the habitats that it grows and reinvesting profits to local groups and tribes to encourage conservation
what percentage of the developing world population relies on traditional medicines (made from wild plants)
80%
about 5 billion people
give 2 issues arising from the international trade of medicinal plants
Overharvesting of wild plants
Habitat destruction- pharmaceutical companies exploiting rainfaroest
Explain the problem of overharvesting medicinal plants
reduces plant populations and biodiversity
may lead to extinction of some species = estimated 4000 plants are threatened
How many plants are threatened from over-harvesting Medicinal plants
4000
What percentage of all terrestrial plant species are held in the rainforest and what percentage of the rainforest has been screened for potential medical use -
70%
1% - could be lots of potential major drugs
Habitat destruction could affect future by taking away potential life saving drugs
How many potential major drugs are estimated to be lost every 2 years due to deforestation
1 every 2 years
What is the alkaloid “Vincristine” found in Rosy periwinkle used in
Chemotherapy
Increased survival rates to 90%
What’s the main pharmaceutical company that uses/buys Rosy periwinkle
Eli Lilly
Major US company that has global sales worth hundreds of millions
How can large pharmaceutical companies try to be more sustainable and help out the locals who cultivate medicinal plants
Diverting profits from sales to local communities = rewards indigenous to help rainforest flourish
Targets problem of Biopiracy = pharmaceutical industry makes huge profit while indigenous pop make very little
What is the name of the drug found in Samoan Rainforest were part of profits were retuned to Samoa + locals in 1980s -
example of a sustainable solution
Prostialin - drug for HIV
Money acts as compensation for protecting rainforest + ensuring future development
