Abstract:
Introduction:
Blood coagulation is a vital, strictly controlled mechanism that creates clots quickly. On
the other hand, blood coagulation abnormalities are frequently noted in several medical
disorders. To find new uses for this plant, this study investigated the anticoagulant activity
of methanolic extracts of Citrus medica fruit, Tecomella undulata bark, and Sesame
indicum seed using in vitro techniques. Material and method:
70% methanol was used to extract the dried and powdered Citrus medica fruit, Tecomella
undulata bark, and Sesame indicum seed. The concentrated dried crude extracts (CMME,
TUME, and SIME) were then subjected to an analysis of their in-vitro anticoagulant
activity on blood coagulation profile, including activated partial thromboplastin time
(aPTT), prothrombin time (PT), and clotting time (CT). Petroleum ether, benzene, ethyl
acetate, and butanol were used in a liquid partitioning process for the CMME and TUME
extracts. The fractions were examined in vitro for their antioxidant potential, blood
coagulation profile, clotting time (CT), prothrombin time (PT), and activated partial
thromboplastin time (aPTT) at varying concentrations (2.5–10 mg/mL). The greatest
anticoagulant fraction (the butanol fraction of TUME (TUBUF) and the ethyl acetate
fraction of CMME (CMEAF)) was subjected to GCMS analysis. Using an animal model
for seven days, the in-vivo anticoagulant activity of CMEAF (100, 200, and 400 mg/kg)
was determined. The bioactive chemical constituents or constituents responsible for the
anticoagulant activity were discovered by FTIR and HPTLC after being isolated by
preparative TLC. Using the LCMS/MS technique, the bioactive molecule was quantified. Result:
Prothrombin time (PT) (20.1, 18.83 seconds) activated partial thromboplastin times
(APTT) (93.67, 63.67 seconds), and clotting time (18.29 ± 0.8, 15.37 ± 0.91 minutes) were
all significantly (p<0.05) extended when administered with CMME and TUME 200 mg/kg.
At a concentration of 7.5 mg/mL, the ethyl acetate fraction of Citrus medica (clotting time:
21.85 minutes; PT: 91.33 seconds; APTT: 114.67 seconds) and the butanol fraction of
Tecomella undulata (17.95 minutes; PT: 48.33 seconds; APTT: 114.67 seconds) showed the highest prolongation significantly (P<0.001) prolonged effect. Ten compounds in
Tecomella undulata's butanol fraction and fifteen compounds in Citrus medica's ethyl
acetate fraction have antioxidant and anticoagulant activity, according to GCMS analytical
data. Additionally, when compared to warfarin as standard, CMEAF prolongs clotting time,
PT, and APTT in the in-vivo model at a dose of 200 mg/kg for five days. It was found that
the amounts of gallic acid, quercetin, and rutin in CMEAF were 514.543 ng, 67.839 ng,
and 53.691 ng, in that order. Ferulic acid, the isolated chemical, was verified using an FTIR
chromatogram and an HPTLC fingerprint. Conclusion:
The results of the study demonstrate the potential of Tecomella undulata, particularly its
butanol fraction, as an antioxidant and anticoagulant, as well as a promising and unexplored
source of bioactive compounds (pentanedioic acid, 2-oxo-dimethyl ester) with potential
therapeutic applications. The ethyl acetate fraction of citrus medica, which is rich in
flavonoids, may include bioactive substances such as gallic acid, quercetin, rutin, and
ferulic acid that have anticoagulant qualities. This offers a possible route for the creation
of brand-new anticoagulant medications. It can be investigated further to create novel
treatments that address a range of medical issues.
