Objective: phytochemical screening and antioxidant activity analyses of selected indoor plants and to evaluate commercial applications.Methods: Qualitative and quantitative phytochemical analyses of alcoholic and aquatic crude extracts of leaves of selected non-flowering indoor plants were assessed using standard protocols and later compared with FTIR analyses. Antioxidant and antibacterial activities of the extracts were studiedResults: Phytochemical analysis of polar solvent extractions of the four selected plants Pedilanthus tithymaloides, Cordyline terminalis, Tradescantia zebrine and Rhoeo discolou. Indicated the presence of tannins in all four varieties terpenoids in 3, flavonols, phytosterols and phenols in two plants, followed by alkaloids. The phytochemical analyses were supported by FTIR reports. Quantitative studies indicated variations in flavonol, tannin and phenols concentrations among the four species. High concentrations of Total flavonols (P. tithymaloides) and Tannins (C. terminalis) were observed. C. terminalis extract showed comparatively highest reducing power followed by R. discolour and P. tithymaloides extracts. Antibiotic Sensitivity Testing indicated P. tithymaloides showed a maximum zone of inhibition compared to R. discolor. C. terminalis plant leaf extract showed a faint zone of inhibition against E. fecalis while others couldnot. Intense colors of C. terminalis and T. zebrine plants could be used as a natural dye as well as pH indicator. Conclusion: The rich concentrations of the tannins from non-flowering indoor plants could be the future option of dyes and dyeing industry as natural colorants as well as pH indicators. These plants were rich sources of phytochemicals (phenols, flavonols, tannins, and phytosterols), with antioxidant and antibacterial activity.

Few studies have conducted experiments in daily living environments to examine the effects of indoor plants on objective aspects of the physical environment. This study examined the effects of plant distance and green coverage ratio on the objective physical environment and subjective psychological perceptions, along with the correlation between the objective physical environment and subjective psychological perceptions regarding indoor plants. A randomized control trial of plant distance and green coverage ratio was conducted in a room located in the basement of a university building in Taiwan. Aspects of the objective physical environment were measured using air quality detectors. Subjective psychological perceptions were evaluated based on the questionnaire responses of 60 undergraduates. The results revealed that (1) regardless of number of plants, the closer the plant, the higher the CO2 level; (2) more indoor plants resulted in higher CO2 and humidity and lower PM2.5, PM10, and temperature; and (3) the lower the levels of fine and suspended particles in the air were, the stronger were the feelings of preference, naturalness of the environment, and pleasure in participants. Indoor plants that can regulate indoor air quality and microclimates without consuming energy warrant greater attention and wider application.
