Abstract Platycladus orientalis, is an evergreen coniferous species of the Cupressaceae family, recognized for its medicinal and ornamental value, largely attributed to its rich phytochemical composition. The present study quantitatively evaluates the phenolics, flavonoids, tannins and saponins, along with antioxidant activities (FRAP and ABTS assays) across leaf, stem and root extracts using three different solvents i.e., acetone, methanol and distilled water. Among the tested extracts, acetonic leaf and root samples exhibited the highest concentrations of bioactive compounds and antioxidant potential. These findings highlight the root as an underexplored source of valuable phytochemicals, contributing to a broader understanding of the plant’s pharmacological relevance. The highest amount of phenolics and flavonoids present in acetonic leaf extract of Platycladus orientalis i.e. 27.29 ± 0.07 mg gallic acid equivalent per gram and 23.01 ± 0.05 mg quercetin equivalent per gram of dry weight. Acetonic stem extract shows highest tannins and FRAP activity i.e. 10.06 ± 0.04 mg tannic acid equivalent per gram and 65.66 ± 0.1 mM ascorbic acid equivalent per gram of dry weight. Acetonic root extract shows highest saponins and ABTS activity i.e. 49.50 ± 0.13 mg diosgenin equivalent per gram and 36.40 ± 0.09% ascorbic acid equivalent per gram of dry weight.
