Antioxidant and Photoprotective Properties of Neotropical Bamboo Species

There are limited published studies related to the mechanical properties of bamboo species in the Philippines. In this study, the shear strength properties of some economically viable bamboo species in the Philippines were properly characterized based on 220 shear test results. The rationales of selecting this mechanical property are the following: (1) Shear strength, parallel to the fiber, has the highest variability among the mechanical properties; and (2) Shear is one of the governing forces on joint connections, and such connections are the points of failure on bamboo structures when subjected to extreme loading conditions. ISO 22157-1 (2017) test protocol for shear was used for all tests. The results showed that Bambusa blumeana has the highest average shear strength, followed by Gigantochloa apus, Dendrocalamus asper, Bambusa philippinensis, and Bambusa vulgaris. However, comparative analysis, using One-way ANOVA, showed that shear strength values among these bamboo species have significant differences statistically. A linear regression model is also established to estimate the shear strength of bamboo from the physical properties. Characteristic shear strength is also determined using ISO 12122-1 (2014) for future design reference.

Bamboo constitutes a family of plants that are very promising and interesting as renewable materials for both large and small structure construction. To be used as an alternative to traditional materials; the understanding of its morphology and mechanical behavior is of crucial importance. As the distribution of fibers and vascular bundles differs for each type of bamboo; several bamboo types have been characterized: Phyllostachys aurea (PA), Arundinaria amabilis (AA) and Dendrocalamus strictus (DS). Morphological analysis has been performed by optical (OM) and scanning electron microscopy (SEM). Differences in density; surface morphology and wall thickness have been found. In fact; PA and AA have shown a great morphological regularity; while DS presents the greatest thickness; to the point that it can be considered full culm. The plant’s own ducts constitute a very important factor for future impregnations and the optimization of mechanical properties for structure construction.

AbstractAn analytical method for the simultaneous determination of ten major functional flavonoids (isoorientin, orientin, vitexin, isovitexin, apigenin, luteolin, tricin, quercetin, rutin, and kaempferol) in different bamboo species was developed by liquid chromatography-tandem mass spectrometry. Chromatographic separation was carried out on a reversed-phase C-18 column with acetonitrile and water as the mobile phases. Detection was performed in negative ion electrospray ionization mode using multiple reaction monitoring mode. The correlation coefficients for the calibration curves ranged from 0.9955 to 0.9997. The limit of detection ranged from 1 to 45 ng/ml. The applicability of this analytical approach was confirmed by the successful analysis of real leaf samples of four bamboo species, family Poaceae: Pleioblastus amarus (Keng) Keng f., Phyllostachys glauca McClure, Phyllostachys edullis (Carrière) J.Houz, and Indocalamus latifolius (Keng) McClure. The total flavonoid contents were 3321.09, 3095.96, 4037.33, and 2808.42 mg/kg for P. amarus, P. glauca, P. edullis, and I. latifolius, respectively. Graphical abstract

Bamboo species is widely used for different purposes in the different parts of World. The variation in properties of the culms of bamboos are affected its use. Shrinkage is one of the physical properties in bamboo and it will affect the products. In this article deals with the variation in shrinkage at different height levels of bamboo culms, different portion in bamboo culms such as outer to inner variation, variation in different age groups of bamboo culms. In addition to this tangential and radial variation in shrinkage also studied. The result shows that a uniform trend in variation was observed based on different parameters.
