英文原文阅读The Perfume Hunters
Sniffing out new smells for use in cosmetics and household products involves blood, sweat and plenty of insect repellent.
Tired, scratched and soaked in sweat, the hunters begin to think of turning back. Time is running out. Dusk is falling and they still haven't caught sight of their quarry. Suddenly they stop. One of the men lifts his head and sniffs. He knows they are close. He scans the undergrowth in the deepening gloom--and suddenly he spots what they have been looking for. There, hidden beneath some leaves at nose height is a tiny spike of flowers, the whole bunch no bigger than a thumbnail. Within minutes, the hunters have set their trap. All they have to do now is wait.
The hard work was worth it. The next morning, there in the trap is a rare
catch--a new sort of smell. For the men in the Madagascan forest are perfume hunters. And instead of rifles, they are armed with nothing more sinister than a few glass jars, a couple of pumps and some tubing which they will use to capture new and exciting fragrances to make our lives smell sweeter.
Ever since the unguentari plied their trade in ancient Rome, perfumers have had to keep abreast of changing fashions. These days they have several thousand ingredients to choose from when creating new scents, but there is always a demand for new combinations. The bigger the "palette" of smells, the better the perfumer's chance of creating something new and fashionable. Even with everyday products such as shampoo and soap, consumers are becoming increasingly fussy. Cheap, synthetic smells are out. Fresh, natural smells are in. And many of today's fragrances have to survive tougher treatment than ever before, resisting the destructive power of bleach or a high temperature wash cycle.
Chemists can now create new smells from synthetic molecules, but nature has been in the business far longer. Plants produce countless fragrant chemicals. Many are intended to attract pollinators. Others are produced for quite different purposes. The fragrant resins that ooze from wounds in a tree, for example, defend it against infection.
The island of Madagascar is an evolutionary hot spot; 85% of its plants are unique, making it an ideal source for novel fragrances. So last October an expedition, including Robin Clery, a chemist, and Claude Dir, a perfume company director, explored two contrasting landscapes in northern Madagascar. Their first stop was a remnant of rainforest in the national park of Montaigne d'Ambre. The second was the tiny uninhabited island of Nosy Hara off the northwest coast.
With some simple technology, borrowed from the pollution monitoring industry, and a fair amount of ingenuity, the perfume hunters bagged 20 promising new aromas in the Madagascan rainforest. Each day the team set out from their "hotel"--a wooden hut lit by kerosene lamps, and trailed up and down paths and animal tracks, exploring the thick vegetation up to 10 meters on either side of the trail. Some smells came from obvious places, often big showy flowers within easy reach. Others were harder to pin down. "Often it was the very small flowers that were much more interesting," says Clery.
In fact, some of the most promising fragrances were given off by resins that oozed from the bark of trees. Resins are the source of many traditional perfumes such as frankincense and myrrh. The most exciting resin that the
