| Description |
Caffeine and chlorogenic acids are the major bioactive
metabolites in beans of coffee, which also contains the
unique diterpene compounds cafestol and kahweol
known to be responsible for hypercholesterolemic
effects in humans. The aim of the study was to profile
cafestol and kahweol in different plant parts of Coffea
species and its beans grown in India, and also in
in vitro raised tissues of commercial Indian species,
viz. Coffea arabica and Coffea canephora. Total quantities
of free diterpene levels were found to be comparatively
higher in beans of C. arabica (1.89 mg g–1)
than in C. canephora (1.13 mg g–1). Other plant parts,
except the roots, showed considerable amount of
cafestol and kahweol. These diterpenes were also synthesized
in somatic embryos and in vitro regenerated
plants of both Coffea species. Somatic embryos of C.
canephora and C. arabica subjected to different hormonal
treatments showed variation in the levels of
total diterpenes. In this study, we were able to profile
cafestol and kahweol levels in in vitro tissues and also
in flowers and zygotic embryos of Coffea species. The
diterpene profiling in in vitro tissues would be of relevance in future to obtain somaclonal variants with
their reduced levels.
