SPICES Biology, History, Production, Uses Janice Ott
“He who controls the spice, controls the universe.” from Dune by Frank Herbert
Food for birds, mammals Sassafras albidum
Beverage, tea Exported by colonists (second to tobacco) Learned from Iroquois tonic after labor topical for rhematism colds, fevers FilE used for thickening gumbo from dried, ground leaf Root beer Soaps, perfumes
1970s safrole liver damage Precursor to MDMA (ecstasy) Safrole is a weak carcinogen in rats Banned by FDA Roots dont’s have safrole Analgesic, antiseptic, fungicide
What “Aromatic natural products that are the dried seeds, buds, fruit, flower parts, bark, or roots of plants, usually of tropical origin.”
All spices are edible. Herbs are not spices, usually leaves. When dried, herbs can be a spice.
HERBIVORY Herbivory is Predation
Defoliators Leaf miner Sap sucker, gall makers
I. PlantsProblem • Decrease fitness • Decrease vigor, biomass • Decrease competitive edge • Decrease reproduction
1. thorns II. Plants Solution Prickly Rose
2. Secondary compounds • Primary compounds are proteins, sugars, starches needed for growth • When herbivory is high produce toxins
Secondary compounds Blackpepper nicotine cinnamon
a. Secondary compounds discourage herbivores • 1) tannins • 2) phenols (aromatics) • 3) terpenes (volatiles)
Alkaloids (affect nervous system) act as insecticides 1. Morphine 2. Cocaine (coca leaves) 3. Caffeine allelopathy chocolate, tea 4. Nicotine 5. Mescaline (Peyote) 6. Nutmeg 7. Morning Glory 8. Nightshades
II. Terpenoids all plants, volatile 1. Essential oils fragrance to deter pathogens deter herbivores humans use for aromatherapy humans use for topical medicine 2. Taxol treat ovarian and breast cancer from fungus on European yew 3. Rubber
Phenols • attract pollinators • Flavonoids, Flavins • 1. Anthocyanins • Grapes, berries • Color depends on pH • Human – protect against heart disease, diabetes, cancer, aging
Salicylic Acid • Willow tree, aspirin, skin care • Hippocrates • Lignin • adds strength to cell walls • Waterproof • Fungal attacks
Secondary are toxic Usually in specific vacuoles Not every plant can produce every product Only produced when needed
Plants response to overgrazing • Fast growing plants protect juvenile parts • Slow growing plants defend entire life
Secondary compounds • b. suppress competitors • c. expensive only for valuable tissue (young) defense only when needed withdraw when no longer needed
d. coevolution • Hares 10 year • Voles 3-4 year • Moose 10-30 year Response: heavier shoots longer sprouts overgrowth at growing tips no flowers this year
III. Herbivory • Most eaten: young, tender tips (papyriferic acid 2x in shoots) high carbon areas birch, willow, aspen, poplar • Least eaten: alder, spruce, old wood
Coevolution Milkweed is toxic
History Accidently –Who???? Used to mask unpleasant Money cardamon = years wages peppercorns = several slaves
