6. MAJOR CHEMICAL CONSTITUENTS AND MEDICINAL PRODUCTS
In addition to maytansine, M. buchananii contains the Where Can I Buy Amoxicillin related compounds maytanprine
and may tanbu tine (Kupchan elt al. , I972b), and normaytansine (Sneden & Beemsterboer, 1980). 500mg Amoxicillin
Maytansine, maytanprine, and may tanbu tine have also been Amoxicillin Cheap isolated from M. graciliramula
S.J.Pei Amoxicillin 500 and Y.H.Li collected in Yunnan (Li Amoxicillin Order source of the compound (Trease & Amoxicillin 500mg Evans, 1978).
Other substances isolated include various anti-tumour phenoldienone Amoxicillin 500 Mg triterpenes from
several species (via Gonzalez Gonzalez e_t al. , 1982). M. laevis has yielded, in addition
to the phenoldicnones, a catechin and some pro-anthocyanidins (Gonzalez Gonzalez et al. ,
7. HARVESTING, CONSERVING AND PREPARATION
Maytansine is obtained from the woody stems of Maytenus buchananii. The method used
by the United States Department of Agriculture Medical Plant Resources Laboratory for
their initial screening of material collected in the Shimba Hills, near Mombasa, Kenya,
was to mechanically chip the stems and then transport the material to a semi-desert region
for Where To Buy Amoxicillin sun drying before shipment to the United States for processing. There was approximately
40-43% loss of moisture on drying (Perdue, no date).
8. ECONOMICS AND MARKETING
Maytansine was first isolated from the seeds of a Maytenus species from Ethiopia.
The species has been variously reported as M. serrata (Hochst. ex A. Rich.) Wilczek,
M. arbutifolia (Hochst. ex A. Rich.) Wilczek and M. ovata (Wall ex Wight & Arn.) Loes.,
an Indian species (Spjut. & Perdue, 1976, Perdue, 1976). This uncertainty well
illustrates the necessity of providing an identifiable voucher specimen when undertaking
a scientific study. The location of the voucher must Amoxicillin Order Online be officially recorded. The yield
of maytansine was only 0.2mg/kg and it was considered doubtful if sufficient fruit would
be available to meet the demand.

An improved source was found in the stems of M. buchananii from Kenya with a yield
of 1.5mg/kg (Perdue, 1976a). More recent findings suggest that the same source from
Tanzania is superior in yield. However, even higher yields of maytansine can be
obtained from another member of the Celastraceae , Putterlickia verrucosa (E.Mey, ex Sond.)
Szyszyl. from South Africa (Perdue, I976b,). Although stems contain 12.3mg/kg of
maytansine, the species was reported to be too widely scattered for Amoxicillin To Buy economic harvesting
unless grown under cultivation (Perdue, 1976a, Kupchan t aj.. , 1977c). It is apparently
easily cultivated in the USA and may prove to be a be better commercial source of the
compound. (Trease & Amoxicillin Amoxil Evans, Amoxil Amoxicillin 1978).
The long term future of the Celastraceae, particularly Maytenus buchananii as a
source of maytansine must be carelly assessed following the discovery by a research
group in Japan that the microsporum Nocardia sp. is a more efficient producer of
maytansinoids (Komoda & Kishi, 1980).
The Amoxicillin Purchase major Buy Cheap Amoxicillin source of supply of maytansine has been M. buchananii in the Shimba Hills
of Kenya. There has been no evidence of regeneration from Buy Amoxicillin coppicing following the
initial harvesting in Amoxicillin Mg 1972, presumably because the plants are easily broken off at
ground level and relatively few stems were left. Cutting stems well above ground level
to encourage coppicing was attempted in 1976, no reports to date on the results. Natural
regeneration from seed seems probable (Perdue, I976a).
Vegetative reproduction by cuttings is practicable. The young plants produced viable
seed within a Amoxicillin Buy year under greenhouse conditions near Washington, DC. (Perdue, I976a).
Field trials in Kenva suggested that plants propagated from seeds did better than plants
Interplanting with shade trees such as Prosopis spp. or Leucaena leucocephala are
beneficial, resulting in better growth and earlier maturity (Haller, 1978).
10. MAJOR DISEASES
No problems evident as yet. Some insect damage reported, but can be controlled
11. OTHER USES
The fruits of M. senegalensis are eaten in Botswana and the yellow-white wood,
being hard and durable and with a fine grain, is used for walking sticks (Irvine, 1961).
In Lesotho, the wood of M. acuminata (L.f.)Loes., M. heterophylla (Ecklon & Zeyher)
N. Robson, M. undata (Thunb. ) Blake lock (and other species is used for building and as
firewood and fighting sticks (Jacot Guillarmod, 1971) and that of M. senegalensis (Lam.)
Exell is an important boxwood Get Amoxicillin in Malawi (Williamson, 1975). In dry areas of Sudan,
