Abstract:
Background: Based on the long history of the medicinal use of Thunbergia laurifolia,
Clerodendrum disparifolium and Rotheca serrata, the extract formulations of these species: T. laurifolia
and C. disparifolium; T. laurifolia and R. serrata; and T. laurifolia, C. disparifolium and R. serrata,
called formulas 1, 2 and 3, were created for detoxification testing to take more advantage of each
species.
Objective: The objective of this study is to estimate the detoxifying effects of studied extract formulations
on human cell and tissue culture as a preclinical trial.
Methods: The major phytochemicals were derived by GC-MS. The detoxification efficacy of these
formulations in cells and DNA levels were derived by MTT and comet assays in toxic PBMCs (incubated
with rice whisky or bathroom cleaner).
Results: The phytochemical constituents were detected at 23.48% phytol and 43.03% oleamide in T.
laurifolia; 12.88% oleamide, 20.93% 9,12,15-octadecatrien, 25.52% squalene, 22.19% butylated hydroxy
toluene and 15.36% vitamin E in C. disparifolium; and 30.41% phytol, 32.78% oleamide, and
12.20%, 9,12,15-octadecatrien-1-ol in R. serrata. The toxic cells treated with the plant formulas 1, 2
and 3 showed no IC50 values, but formulas 1 and 2 displayed higher efficacies than formula 3 did. The
comet assay indicated that the experiments (the treatment on toxic cells with the plant formulas) induced
significant (p < 0.05) DNA damage compared to the negative control due to poisoning occurring
before administration of the plant formulas. The OTM of the controls was significantly (p < 0.05)
longer than the experimental samples showing significantly reduce the toxicity of the created formulations.
Conclusion: The formulas showed high detoxification efficacies and formulations 1 and 2 resulted in
higher levels of detoxification than formulation 3, especially in immediate treatment after receiving
toxic substances.
