Pressurized hot water extraction (PHWE).
TL;DR: With some modifications, a scaled-up PHWE could extract a higher amount of desirable compounds from solid and powdered samples such as plant and food materials, which can be a potential lead for drug discovery or development of disease-resistant food crops.
Journal ArticleDOI
Pressurized hot water extraction of bioactive or marker compounds in botanicals and medicinal plant materials
TL;DR: Surfactant assisted PHWE was found to enhance the extraction of thermally labile and more hydrophobic species in medicinal plants at a lower temperature and the addition of small amount of surfactants in PHWE is highly suited for the determination of bioactive or marker compounds in medicinal Plants.
Journal ArticleDOI
Extraction methods and chemical standardization of botanicals and herbal preparations
TL;DR: The focus of this review paper is on the analytical methodologies, which included the combination of sample preparation tools and chromatographic techniques for the chemical standardization of marker compounds or active ingredients in botanicals and herbal preparations.
Journal ArticleDOI
Simultaneous analysis of different classes of phytohormones in coconut (Cocos nucifera L.) water using high-performance liquid chromatography and liquid chromatography-tandem mass spectrometry after solid-phase extraction.
TL;DR: A high-performance liquid chromatography (HPLC) method was developed for the simultaneous determination of various classes phytohormones, including indole-3-acetic acid (IAA), indole -3-butyric acid (IBA), abscisic acid (ABA), gibberellic Acid (GA), zeatin (Z), N(6)-benzyladenine (BA) and 2,4-dichlorophenoxy
Journal ArticleDOI

Eng Shi Ong,Shea Mei Len +1 more
TL;DR: In this paper, the authors used a laboratory-made system for the extraction of thermally labile and reasonably polar components such as berberine in coptidis rhizoma, glycyrrhizin in radix glycrhizae/liquorice and baicalein in scutellariae radix.
