“…The ratio of silica/ash content of SBW is higher than SPW and also higher than the research results on Gramineae, such as bagasse 92% (Sapawe et al 2018). In Gramineae plants, silica plays a role in straightening the leaves (Tripathi et al 2017) while in other plants, silica plays a role in increasing plant growth (Artyszak 2018). Silica in biomass can reduce the calorific value (Demirbas 2007) and dulls saw (Sommer et al 2015).…”

Abstract. Siruru H, Syafii W, Wistara I. N. J, Pari G. 2019. Characteristics of Metroxylon rumphii (pith and bark waste) from Seram Island, Maluku, Indonesia. Biodiversitas 20: 3517-3526. Sago (Metroxylon rumphii Martius) pith waste (SPW) and sago bark waste (SBW) are lignocellulosic materials that can be used for various needs directly or indirectly. It is necessary to understand SPW and SBW characteristics to maximize their utilization. In this study, we analyzed the proximate, ultimate, and crystallinity by XRD, the functional groups by FTIR, morphology by SEM, and the derivate analysis of hot water-soluble extractives by GCMS. The contents of SPW and SBW hot-water soluble extractive, lignin, and holocellulose were 57.7 and 4.9%, 6.1 and 29.4%, and 45.74 and 66.74%, respectively. The volatile matter, ash content, silica, fixed carbon, C, H, and O contents of the SPW and SBW were 81.48 and 84.56%, 1.30 and 3.04%, 1.25% and 2.03, 12.77 and 18.06%, 37.93 and 44.64%, 6.37 and 6.49%, and 47.75 and 51.10%, respectively. The degree of crystallinity of SPW was 15.04%, while that of SBW was 47.28%, where both have a monoclinic structure with the main peak by 2Ɵ 16° and 26°. SPW and SBW contained several minerals such as silica, boron, sulfur, and phosphorus. The surface morphology of the SPW was porous with a small diameter and thin cell wall, while that of SBW was covered by minerals. Nitrogen, alcohol, and sugar group compounds were found more in SPW, whereas phenol compound was more in SBW. SBW has high lignin content and SPW has a very large amount of hot water-soluble extractive.

“…1). There are two opposing techniques, known as "Top-down process technology" and "Bottom-up process technology," for producing nanosuspensions [7,25,[27][28][29]. The top-down method adopts a disintegration strategy starting with large particles and progressing to microparticles and nanoparticles.…”

The process that occurs at the molecular level and at the nanoscale is the subject of nanotechnology. Nanotechnology includes nanosuspension. Nanosuspension is a colloidal dispersion of medication particles that are nanometer-sized and stabilized with surfactants. To manufacture and scale up nanosuspensions, conventional size reduction tools such as media mills and high-pressure homogenizers as well as formulation strategies including precipitation, emulsion-solvent evaporation, solvent diffusion, and microemulsion procedures can be successfully used. The main elements to be taken into consideration for the effective manufacture and scale-up of nanosuspensions are maintaining the stability in solution as well as in the solid form, and resuspendability without aggregation. The flexibility for surface modification and mucoadhesion for drug targeting have substantially broadened the scope of this innovative formulation method as a result of the significant improvement in bioavailability. Extensive research is now being done on the use of nanosuspensions in various drug delivery methods, including oral, ophthalmic, brain, topical, buccal, nasal, and transdermal routes. The majority of permeability limiting absorption and hepatic first-pass metabolism associated difficulties that negatively affect bioavailability can be resolved with oral drug delivery of nanosuspension with receptor mediated endocytosis, which is a promising capability. The development of enabling technologies like nanosuspension can address several formulation issues that protein- and peptide-based medicines currently encounter

“…Plants naturally absorb silicic acid, where it is polymerized as solid silica bodies, silica cells, or phytoliths [24]. In these phytoliths, hydrogen and cellulose bond within the cell walls as silicon dioxide, SiO 2n H 2 O [25]. Tables 1 and 2 show the content and average intake of silicon from various common sources.…”

Silicon is a microelement that performs a number of important functions in the human body, being involved in the formation and maintenance of normal osteocartilaginous connective tissue, such as skin, hair, and nails, and having beneficial effects in the prevention of cardiovascular and neurodegenerative diseases. Natural sources of silicon include fruits, vegetables, cereals, and mineral water. European and North American diets are generally low in silicon, which correlates with a diet high in processed foods. Dietary silicon deficiency can be overcome by the consumption of high bioavailability silicon-rich foods and the use of silicon supplements. A good form of supplementation is orthosilicic acid (OSA), usually stabilized by the introduction of a methyl group, choline, or vanillin. OSA is naturally found in diatomaceous earth in the form of amorphous silica and extracts from silicon-rich plants, e.g., horsetail (Eguiseti herba L.) and nettles (Urtica dioica L.). This article presents the characteristics of the various sources of silicon and their bioavailability and safety of use, with particular reference to the sources used in functional foods and dietary supplements. There is a great need to produce functional foods containing dietary silicon, together with other scarce mineral components.
