The aim of the present investigation was to evaluate the phytochemical and biological properties (antioxidant, thrombolytic, astringent and pro-coagulant) of Tagetes lucida. Freshly prepared crude extracts of Tagetes lucida were qualitatively tested for the presence of various chemical constituents including carbohydrates, alkaloids, flavonoids, glycosides, gums, steroids and saponins. These were identified by observing characteristic color changes using standard procedures. In phytochemical investigations, the presence of carbohydrates, alkaloids and flavonoids were identified but glycosides, gums, steroids and saponins were absent. The crude methanolic extract of Tageres lucida showed significant thrombolytic activity. The plant leaves extracts had anti-oxidant activity but not in a significant manner. Medical astringents are considered to stop or slow bleeding and to help wounds heal. The leaves of Tagetes lucida showed astringent properties. Procoagulant platelets are predominantly localized at thrombus surface. The leaves of Tagetes lucida showed pro-coagulant properties.
