Crystal structure determination and thermal behavior upon melting of p -synephrine [PDF]
Thermochimica Acta, 2016 The crystal structure of p-synephrine was solved from a high-resolution X-ray powder diffraction pattern optimized by energy-minimization calculations using the Dreiding force field. The title compound crystallizes in a monoclinic system (space group P2 1 /c, Z = 4, with a = 8.8504(11) A, b = 12.1166(15) A, c = 9.7820(11) A,  = 122.551(2) • , V = 884 ...

A review of the receptor-binding properties of p-synephrine as related to its pharmacological effects. [PDF]
Oxid Med Cell Longev, 2011 Bitter orange (Citrus aurantium) extract and its primary protoalkaloid p-synephrine are used widely in weight loss/weight management and sports performance products. Because of structural similarities, the pharmacological effects of p-synephrine are widely assumed to be similar to those of ephedrine, m-synephrine (phenylephrine), and endogenous amine ...

Self-reporting molecularly imprinted polymer with the covalently immobilized ferrocene redox probe for selective electrochemical sensing of p-synephrine [PDF]
Sensors and Actuators B: Chemical, 2021 Molecularly imprinted polymers (MIPs) belong to the illustrious examples of bio-mimicking recognizing materials.1 They have found numerous applications in the fabrication of selective chemosensors.2 Their analytical parameters, such as sensitivity, selectivity, and detectability, are almost as high as those of biosensors.

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using <sup>1</sup>H NMR spectroscopy. [PDF]
FEBS Open BioWe investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Acute consumption of p-synephrine does not enhance performance in sprint athletes
Applied Physiology, Nutrition, and Metabolism, 2016 P-Synephrine is a protoalkaloid widely used as an ergogenic aid in sports. This substance has been included in the World Anti-Doping Agency monitoring program, although scientific information about its effects on performance and athletes’ well-being is scarce.

PHYSICAL STABILITY TESTING OF P-SYNEPHRINE PREPARED AS TRANSFERSOME GEL
International Journal of Applied Pharmaceutics, 2017 Objectives: While p-synephrine exhibits lipolytic activity, it also has a low oral bioavailability as well as hydrophilic characteristic, so it is difficult forit to penetrate the epidermis if it is made into transdermal preparation. The purpose of this research was to increase the penetration of p-synephrineby preparing it as transfersome gel ...
