TLDR
In this article, three different processes have been applied to extract the natural hydroxyapatite: thermal decomposition, subcritical water and alkaline hydrothermal processes, and the results obtained by many physiochemical analyses have indicated that all the utilized methods have the ability to eliminate the organic compounds present in the bovine bones.About:

Technologies for Extraction and Production of Bioactive Compounds to be Used as Nutraceuticals and Food Ingredients: An Overview
G. Joana Gil-Chavez,José A. Villa,J. Fernando Ayala-Zavala,J. Basilio Heredia,D.R. Sepulveda,Elhadi M. Yahia,Gustavo A. González-Aguilar +6 more
TL;DR: The most commonly used methods for their extraction are the conventional liquid-liquid or solid-liquid extraction and the advanced methods include pressurized liquid extraction, subcritical and supercritical extractions, and microwave-and ultrasound-assisted extractions.

Extracting hydroxyapatite and its precursors from natural resources
TL;DR: This review looks at the progress being made to extract Hydroxyapatite and its precursors containing trace amount of beneficial ions from biological resources like animal bones, eggshells, wood, algae, etc.
Journal ArticleDOI
Substituted hydroxyapatites for bone regeneration: A review of current trends.
TL;DR: It can be shown that a minor substituent cannot only alter the microstructure, stability and crystallinity of the HA structure in an implant, but also have a significant effect on bone cells colonizing the implant, which in turn can influence the new bone formation and bone remodeling processes.
Journal ArticleDOI
Hydroxyapatite-polymer biocomposites for bone regeneration: A review of current trends.
TL;DR: This review article summarizes the past and recent developments in the evolution of HA-polymer biocomposite implants as an "ideal" biomaterial scaffold for bone regeneration.

Chemical and physicochemical characterization of porous hydroxyapatite ceramics made of natural bone.
TL;DR: The properties of a porous hydroxyapatite ceramic produced by sintering of bovine bone were investigated by using a number of physicochemical methods such as scanning electron microscopy, SEM in combination with energy dispersive X-ray spectroscopy, mercury intrusion porosimetry, krypton-adsorption, contact angle measurements, wide angle X-rays diffraction.
