HANOI, Jan. 9 (Xinhuanet) -- Vietnamese scientists plan to producea main
material for production of anti-bird flu medicine Tamiflu from anise, a small
tree, in the next few months, according to local newspaper Young People on
Monday.
Vietnam's Chemistry Institute plans, in the next five or six months, to
make Oseltamivir (active agent of Tamiflu) on a laboratory basis out of star
anise, an aromatic Asian evergreen tree having purple-red flowers and star-like
clusters of anise-scented fruit.
The institute's scientists have found out a process of extracting shikimic acid,
a key material to synthesize Oseltamivir, from anise fruit. One hundred
grams of the fruit can turn out 5-10grams of shikimic acid, or six grams of the
fruit can make one Tamiflu capsule.
Vietnam's Health Ministry announced in November 2005 that it had inked a
deal with Roche, Swiss producer of Tamiflu, under which the firm would supply
Vietnam with necessary materials and techniques to manufacture the medicine in
the country. Roche also agreed to supply Vietnam with 25 million Tamiflu
capsules in case of bird flu pandemics.
The northern province of Lang Son with over 8,000 hectares of star anise,
the biggest anise-growing area in Vietnam, annually produces 5,000-6,000 tons of
the dried fruit.
Now, the country uses anise as a spice or extracts oil from it for
production of traditional medicines and export.
Star anise fruit is a star-shaped, dark brown pod that
containsa pea-sized seed in each of its eight segments. It is a commonly used
spice and tea flavoring in Asian cuisines, and widely used toflavor liqueurs and
baked goods in Western cultures. Enditem |
