Centella asiatica, a weakly aromatic plant that flourishes in wet tropical and sub-tropical areas as
a medicinal species since ancient times. It contained important terpenoids that impart important
medicinal values. Currently, studies on the terpenoid content of various Centella asiatica
phenotypes have shown not only variable content but variable growth rates of different
phenotypes that can affect future selection of phenotypes. The use of mathematical growth
modelling can reveal important growth constants and discriminate between faster and slower
growth phenotypes. Two Centella asiatica phenotypes from South Africa is modelled using the
modified Gompertz model and the results showed that the C. asiatica Type-1 exhibited a faster
growth rates and a shorter lag period at 0.152 day-1 and 2.313 day than another phenotype; C.
asiatica Type 2 with a growth rate and a lag period of 0.067 day-1 and 3.363 day, respectively.
The data indicates that different phenotypes of C. asiatica can have different growth rates and
lag period and this can be important for selection of phenotypes to be used as the best bioactive
peptides producer.
