Impact of Nanopowders on Exraction Yield of <i>Centella asiatica</i>

Abstract

Centella asiatica (C. Asiatica) is a traditional herb that has been used in raditional medicine especially in Asia region. Recently the pharmalogical study of Asiatic acid (AA) which is one of bioactive constituents in C. Asiatica has been studied and revealed that this compound has a potential to be use in medicine area. The objective of this paper is to produce nanoparticles C. Asiatica by Planetary Ball Mill (PBM) and determined the effect of nanonization on extraction yield of asiatic acid. The particles were analyzed using particle sizer to determine size of particle produce and the morphology was evaluated through FESEM. As a result, the mean particles size of nanopowders was 501.10 nm and the extraction of asiatic acid using nanopowders showed 82.09 % higher than original powder.

Selectivity of Current Extraction Techniques for Flavonoids from Plant Materials

“…Decreasing the particle size enhances surface contact between samples and extraction solvents. A particle size smaller than 0.5 mm is optimal for efficient extraction [81]. The usage of powdered dried plant material leads to effective extraction of flavonoids [67,74,79,82,83].…”

A Review on the Extraction Methods Use in Medicinal Plants, Principle, Strength and Limitation

“…This particular pre-preparation is important, as for efficient extraction to occur, the solvent must make contact with the target analytes and particle size smaller than 0.5 mm is ideal for efficient extraction [6]. This particular size of particle was mentioned in Sulaiman et al, preparing vegetable samples that was asiatica produced by Planetary Ball Mill (PBM) showed 82.09% higher yield compared to micro powder using maceration technique in 90% methanol for 3 days [7]. Particle size was a major factor when using enzyme-assisted extraction.…”

Rosmarinus officinalis L. (rosemary) as therapeutic and prophylactic agent

“…Thus, powder samples have better contact with the solvent than crushed samples. Nanoparticles containing Centella asiatica presented higher yields than microparticles, when in contact with methanol [32].…”
