“…Polyphenols are natural antioxidant from plants and are consumed in the forms of vegetables, fruits and beverage such as tea, coffee and wine 24 . The known in-vitro antioxidant properties of catechins and other polyphenolic compounds of tea have led to interest in the potential health benefits of tea consumption 25,26 . In this experiment, there is a significant (P<0.05) difference between in leaf and dust of black tea aqueous extracts.…”

The present study is designed to investigate the comparison level of antimicrobial, antioxidant properties and as well as the total phenolic content estimation of aqueous extract between dusts and leaf black tea. Antimicrobial assay as well as antioxidant activity of phyto-compounds in both types of black tea was detected by using agar well diffusion and chromatographic technique respectively. Total antioxidant activity and phenolic content were measured by using coloriemetric method. In comparison level the antimicrobial activity and screening of phytochemical compounds like saponins, phenolic compounds & tannins, flavonoids, triterpenoids were significantly (P<0.05) different in both aqueous extract of leaf black tea and dust black tea. Total phenolic contents in the leaf black tea were 130.51mg Gallic acid equivalent/g of dried aqueous extract. In conclusion the leaf black tea has potential to be used as a natural antioxidant which is attributed to the rich presence of secondary metabolites and exhibit medicinal as well as physiological activities.

“…The yield (%) of 8.16% in this study is considered relatively high compared to the study of [44] that is 3.05% using successive hot continuous Soxhlet extraction. Methanolic extract of Clitoria ternatea leaves had an extraction yield of 20.29 ± 0.23% involving the utilization of 80 ± 1 °C water bath for 60 minutes as shown by another study [43].…”

Clitoria ternatea is traditionally used as medicine in Ayurveda and had been found to exhibit antibacterial activities due to its rich phytochemical contents. Due to the issue of resistant bacteria emergence and side effects of synthetic antibacterial agents, investigation of plant’s antibacterial potential is important. In this study, the methanolic C. ternatea leaves extracts were investigated for phytochemical content and antibacterial activity. Phytochemical content was investigated quantitatively focusing on the total phenolic content (TPC) and total flavonoid content (TFC), determined by Folin-Ciocalteau method and Aluminum-chloride method, respectively. The antibacterial potential of the plant’s extract was analyzed by disk-diffusion method of concentrations (12.5, 25, 50, 100 mg/mL), ampicillin and methanol act as positive control and negative control, respectively. The extraction yield of methanolic C. ternatea leaves extracts obtained by maceration method is 8.16%. The TPC and TFC of C. ternatea leaves extract are 0.66116 ± 0.43455 mg GAE /g and 0.31333 ± 0.057735 mg QE /g respectively. The disk-diffusion antibacterial assay showed no inhibitory activity of C. ternatea extracts against Escherichia coli. This might be attributed to the lack of potency of C. ternatea extracts at their current concentration, and the low content of TPC and TFC in the extracts. This had partially proved that concentration of the extracts used is crucial in antibacterial activities. Discrepancy of antibacterial results in C. ternatea observed between different studies might be attributed to the different methodologies. In conclusion, C. ternatea has been seen as a high potential plant in terms of antibacterial activity, but conditions during experiment poses high impact on the result of antibacterial assay. The findings from this study had provided valuable information to the field of phytochemistry and attempted to broaden the uses of medicinal plants, in which this can indirectly contribute to preservation of traditional knowledge and conservation of biodiversity.

“…Figure3displays the functional groups in terms of infrared peaks of untreated and chemically treated coconut shell agro-waste powder. The untreated sample showed peaks at 3344 and 2941 cm − 1 ascribed to stretching and vibration of O-H and C-H con rming the presence of α-cellulose, water, and alcohol; and hemicellulose, cellulose, and other organic compounds presence, respectively[47],[48]. The peak recorded at 1726 cm − 1 is ascribed to strong carbonyl (C = O) stretching vibrations of acetyl groups in lignin, hemicellulose, and pectin.…”

The use of environmentally friendly materials for industrial applications has increased tremendously in the past decades due to environmental concerns and the problems associated with the use of synthetic materials. Coconut shell is an agro-waste and source of biomass that has attracted increasing research attention as a potential alternative reinforcing material to synthetic. This study considered chemical modification and characterization of coconut shell powder in an attempt to enhance compatibility with the hydrophilic polymer matrix. The coconut shell powder was treated with alkali (NaOH), bleaching and combined NaOH-bleaching solutions before investigating the surface morphology, chemical transformations, and thermal stability. It was discovered from the results that combined treatment gave the optimum enhancement. The surface treatments resulted in chemical transformations of coconut shell powder, while FTIR analysis confirmed partial removal of lignin and hemicellulose. Also, XRD investigation revealed that surface treatments enhanced the crystallographic properties, whereas TGA analysis showed that the thermal stability of the treated sample was enhanced. Hence, treated coconut shell powder can be considered a sustainable and environmentally friendly reinforcing material for lightweight polymer composites needed for industrial applications, such as automotive dashboards and panels.
