You may not find them at your local fruit
stand—unless you live in India, Brazil and Jamaica—but gamboge,
jaboticaba and akee might hold the key to defeating certain forms of
cancer, as well as other ailments.

The antioxidant compounds of these tropical
fruits are being identified and studied by three CUNY doctoral students,
each of whom has been awarded a fellowship from the National Institutes
of Health to support their exploration for alternative medicines. Antioxidants
are considered to be anti-aging compounds because they can prevent oxidative
damage that can lead to cancers, heart disease and neuro-degenerative
disorders like Alzheimer’s disease.
The students are working at Lehman College in the Bronx, which houses
CUNY’s
Doctoral Program in Plant Sciences, and
in the laboratory of Dr. Edward Kennelly, a member of the Lehman biology
faculty whose findings on botanical dietary supplements, natural sweeteners
and anti-cancer plants have been widely published in scientific journals.
After studying gamboge for almost three years, Scott Baggett says that
the compounds he isolated from this apple-sized fruit—which is
used to dye Buddhist robes their distinctive bright yellow—are
proving to be more powerful so far at killing colon-cancer cells than
chemotherapeutic drugs currently in use. Tests are under way at the
lab of Dr. I. Bernard Weinstein, director emeritus of the Herbert Irving
Comprehensive Cancer Center at Columbia University, one of the nation’s
premier research centers for therapies to prevent and treat cancer.
The results, says Baggett, a graduate
of the University of California at Davis, are “very promising,”
but he cautions that a long research road lies ahead and that clinical
trials, if the studies reach that stage, would probably not begin for
many years. A pan-tropical fruit, gamboge grows in locales in Southeast
Asia and is usually not eaten by local populations but brewed into a
broth that is used to treat gastric problems.
Another CUNY doctoral student, Kurt Reynertson,
is studying jaboticaba. Eaten just like the grape it resembles, jaboticaba
is popular mainly in Brazil and other countries in South America but
also is grown in southern Florida, where the fruit is sometimes sold
at specialized stands. Florida is also home to the Fruit and Spice Park,
where the CUNY researchers, collaborating with Margaret Basile and other
local scientists, obtain home-grown versions of the species they are
studying.

Reynertson, a graduate of the University
of Wisconsin, is isolating and purifying the compounds in jaboticaba
that are responsible for its antioxidant activity and dark purple color.
Similar compounds are known to have positive biological effects in cranberries,
grapes and other related species—including anti-aging, anti-inflammatory
and anti-oxidant qualities. Reynertson feels he might be on the trail
of an entirely new compound. Dr. Kennelly notes that “new antioxidant
compounds are not common,” but “we are very excited when
we hit upon new ones.”
The third CUNY researcher, Ainsley Parkinson, a graduate of SUNY Binghamton,
has just started his research on the compounds in akee (or ackee) and
Jamaican cherry. For Parkinson, the studies bring him back to the land
of his birth, where codfish and akee is a
Plant
Science Computer Lab Inaugurated
September 15 marked the celebration of a new computer lab
at Lehman College that will allow students to use advanced
software in plant research. Twenty-five computer stations
loaded with more than 100 software licenses, valued at $200,000,
have been donated by the Waters Corporation in Massachusetts.
These will allow faculty to teach entire classes how to use
software-controlled high-performance liquid chromatography,
or chemical separation, equipment. Called HPLC for short,
this hardware allows for the analysis, identification, and
quantification of compounds extracted from plants. Familiarity
with the Waters software, says Lehman’s chair of biological
sciences Thomas Jensen, will give Lehman plant science graduates
“a distinct advantage over most other college graduates
seeking research positions in the sciences.” |

national dish. Either red or yellow in color, with very small seeds, akee
has a dark side—if picked too soon, it can be poisonous. As a result,
the fruit is imported into the United States only after it has been cooked
and canned.
Dr. Kennelly has hopes that the recognition from NIH will mark the beginning
of Lehman’s growth as a major center for this type of medicinal
plant research. The doctoral program Lehman houses is already one of
the largest in the country for the plant sciences and the only one of
its kind in New York City.
