Unveiling the nutritional and bioactive potential of bamboo (Bambusa tulda Roxb.) tea: A phytochemical and spectroscopic study
This study investigated the physicochemical properties and antioxidant activity of Bambusa tulda tea. The tea exhibited low moisture and ash content, indicative of good drying quality. Its acidic pH was attributed to the presence of organic acids. Phytochemical analysis confirmed the presence of car...

| description | This study investigated the physicochemical properties and antioxidant activity of Bambusa tulda tea. The tea exhibited low moisture and ash content, indicative of good drying quality. Its acidic pH was attributed to the presence of organic acids. Phytochemical analysis confirmed the presence of carbohydrates, reducing sugars, triterpenoids and cardiac glycosides. The dry extract contained higher levels of phenolics and flavonoids compared to the infusion, resulting in stronger antioxidant activity, as demonstrated by a lower IC50 value of 3.794 in the DPPH radical scavenging assay. Furthermore, silica (SiO₂) was extracted from the tea leaves and characterized using X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). These analyses revealed an amorphous structure and spherical morphology. Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive Spectroscopy (EDS) analyses corroborated the spherical morphology and elemental composition of the SiO₂. The extracted SiO₂ effectively degraded methylene blue and Congo red dyes under sunlight, highlighting the potential of B. tulda tea as a sustainable source of SiO₂ for environmental remediation. |
