| dc.description.abstract | This study was carrieds out to evaluate the phytochemical, antibacterial, and antioxidant activity of B.blumeana var. luzonensis and S. brachycladum shoot ethanol and hot water extracts. Phytochemical screening revealed that cardiac glycosides, flavonoids, saponins, tannins and terpenoids were present in all bamboo shoots extracts. Steroidwas present only in the ethanol extracts of B. blumeana var. luzonensis and S. brachycladum shoots. Antibacterial activity as eradicant and protectant of the four bamboo shoot extracts were determined using disc diffusion method. Eradicant test against E. coli revealed that S. brachycladum shoot ethanol extract had the biggest zone of inhibition at 12 and 24 hours of incubation with 8.68 mm and 8.36 mm. On the other hand S. brachycladum shoot hot water extract produced the widest zone of incubation against S. aureus at 12 and 24 hours of incubation with 13.40 mm and 15.32 mm. Statistical analysis of four bamboo shoot extracts were comparable to the negative control whichsuggest the weak antibacterial activity as eradicantagainst the two human pathogen. Meanwhile, for the protectant test, E. coliproduced the smallest zone of colonization in B. blumeana var. luzonensis ethanol extract with 7.14 mm and 9.97 mm. Whereas S. aureusformed the smallest zone of colonization in S. brachycladum shoot ethanol extract of 6.28 mm after 12 hours of incubation while B. blumeana var. luzonensisethanol extracts had the smallest zone of colonization at 24 hours of incubation. Additionally, antioxidant analysis showed that all four bamboo shoot extracts possessd DPPH radical scavenging activity B. blumeana var. luzonensis shoot ethanol extract had the highest yield with 64.80% radical scavenging activity and 27.59 mg AAE/g sample phenolic content. The results of the study revealed the presence of phytochemicals in the tested bamboo shoot extracts which led to its antimicrobial and anti-oxidant properties. | |
