Subjec t : S t a t u s on P l a n t s Act ive from Kenya and Tanzania
To : R. E . Perdue, Jr . , Chief Medicinal P l a n t Resources Laboratory
A c t i v i t y d a t a on p l a n t s a c t i v e from Kenya and Tanzania w e r e drawn toge the r from our a c t i v e books, p rog res s r e p o r t s by D r s . Cole and W a l l , and D r . Ha r twe l l ' s paper 'Types of Anticancer Agents I s o l a t e d from P l a n t s . "
The a c t i v e books con ta in occas iona l n o t e s on r e - c o l l e c t i o n s t h a t have f a i l e d o r reconfirmed. These n o t e s appear t o b e based on progress r e p o r t s , te lephone conversa t ions and correspondence, b u t documentation is n o t always c i t e d .
Progress r e p o r t s a l s o mention t h a t re -co l lec t ions ' f a i l o r reconf i rm, b u t completely l a c k r e fe rence t o PR-numbers. It would appear t o b e more u s e f u l t o s t a t e , f o r example, t h a t "PR-42638 was margina l ly a c t i v e i n P-388", r a t h e r than "A l a r g e sample received from t h e USDA showed margina l a c t i v i t y in P-388 ." From reviewing p rog res s r e p o r t s , o t h e r k inds of u s e f u l in format ion might become evident i f PR-numbers were c o r r e l a t e d wi th samples. For example:
The o r i g i n a l sample of Chenopodium procerum was s t a t e d a s margina l ly a c t i v e i n P-388, b u t t h e one r e - c o l l e c t i o n was i n d i c a t e d t o be h igh ly a c t i v e i n P-388. I could determine t h i s on ly a f t e r reviewing a l l of D r . Cole 's p rog res s r e p o r t s . I f I had looked only a t D r . Cole ' s most r ecen t p rog res s r e p o r t , t h e r epo r t ed h igh a c t i v i t y in P-388 might b e quest ioned a s be ing r e l a t e d t o an e x t r a c t made from t h e o r i g i n a l sample, t h e r e - c o l l e c t i o n , o r bo th .
I n t e r e s t i n g l y , t h e h i g h e r a c t i v i t y w a s from a sample of p l a n t s t h a t were dead and d r i e d when co l l ec t ed i n t h e f i e l d .
I have compiled two l i s t s : one r ep re sen t ing p l a n t s a c t i v e from Kenya and t h e o t h e r r e p r e s e n t i n g p l a n t s a c t i v e from Tanzania. Spaces w e r e l e f t b l ank where d a t a a r e needed o r n o t y e t a v a i l a b l e .
