TLC Preparative Purification of Picrocrocin, HTCC and Crocin from Saffron

Journal of Food Science, 1992
ABSTRACT A method for the extraction and purification of saffron secondary metabolites was developed. Among the solvents checked water was the most convenient for picrocrocin, 2,6,6‐trimethyl‐4‐hydroxy‐1‐car‐boxaldehyde‐1‐cyclohexene (HTCC) and crocin extraction from saffron stigmas.

Ultrasound-assisted extraction of saffron bioactive compounds; separation of crocins, picrocrocin, and safranal optimized by artificial bee colony

open access: yesUltrasonics Sonochemistry, 2022
In this work, a four-factor five-level full factorial central composite design (CCD) was used to optimize the ultrasound-assisted extraction (UAE) of saffron major components, namely picrocrocin, safranal and crocin. The process parameters included ethanol concentration (0-100%), extraction time (2-10 min), duty cycle (0.2-1.0) and ultrasonic amplitude

Quantification of crocin, picrocrocin and safranal in saffron stigmas obtained from sounded corms with acoustic waves

Phytochemical Analysis, 2021
AbstractIntroductionPlant acoustic frequency technology (PAFT) is the effect or treatment of a plant with a specific frequency sound wave.ObjectiveThe sound waves with different frequencies and a sound pressure level 77 dB were emitted on the saffron corms in a controlled environment using aeroponic cultivation and the contents of crocin, picrocrocin ...

A Picrocrocin-Enriched Fraction from a Saffron Extract Affects Lipid Homeostasis in HepG2 Cells through a Non-Statin-like Mode

open access: yesInternational Journal of Molecular Sciences, 2023
Dyslipidemia is a lipid metabolism disorder associated with the loss of the physiological homeostasis that ensures safe levels of lipids in the organism. This metabolic disorder can trigger pathological conditions such as atherosclerosis and cardiovascular diseases. In this regard, statins currently represent the main pharmacological therapy, but their

Analysis of a packed-bed reactor for hydrolysis of picrocrocin by immobilized β-glucosidase

Enzyme and Microbial Technology, 1993
Abstract β-Glucosidase was immobilized onto nylon-hydrazide and employed for picrocrocin hydrolysis in a continuous packed-bed reactor (PBR). 2,6,6-Trimethyl-4-hydroxy-1-carboxaldehyde-1-cyclohexene (HTCC) was collected from the reactor effluent and dehydrated to safranal, to obtain up to 20 g l−1 h−1 of safranal, the essential oil from saffron ...
