Authors: Oliver S. Marasigan, Elvina O. Bondad, Mario Angelo M. Mundin & Shereyl A. Daguinod
Marasigan et al. (2023) investigated the effect of locality and axial position on the morphological, physical, and mechanical properties of iron bamboo (Guadua angustifolia Kunt.) and solid bamboo [Dendrocalamus strictus (Roxb.) Nees] from Laguna, Baguio City, and Nueva Vizcaya.
Results showed that iron and solid bamboo from Laguna are suitable for construction and engineered bamboo applications, while bamboo from Baguio City and Nueva Vizcaya is recommended for structural applications that require high strength but not necessarily large culms. These findings substantiated Philippine-grown iron and solid bamboo as eco-friendly and sustainable raw materials in green architecture.

Phytochemical screening, antioxidant, and antimicrobial properties of sequential extracts of stems of Arcangelisia flava
Authors: Kimberly M. Delica, Kim Wilmer M. Balagot, Rowena E. Ramos, Rebecca B. Lapuz, Jefferson A. Collera & Cherrie Mae J. Martinez
Delica et al. (2024) examined the antioxidant and antimicrobial properties of Arcangelisia flava, commonly known as albotra. Results showed that antimicrobial activities may be possible because of the phytochemicals identified in the extracts of A. flava stems. Moreover, this study revealed that the methanolic extract of A. flava stems is an excellent candidate for the purification and isolation of compounds responsible for antioxidant and antimicrobial activity.
