Acta Chromatographica > 2024 > Vol. 36, no. 1 > 59--66

A simple, rapid, sensitive and eco-friendly liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for simultaneous determination of free cordycepin (3′-deoxyadenosine) and isocordycepin (2′-deoxyadenosine) in 10 kinds of Cordyceps samples. The samples were prepared by ultrasonic extraction at 75 °C for 30 min with boiling water as the extraction solvent. The LC separation...

Acta Chromatographica > 2024 > Vol. 36, no. 1 > 31--44

Rationale: The bark of Eucommia ulmoides and the roots of Achyranthes bidentata are commonly used in traditional Chinese medicine, and their pairing appears in many traditional Chinese medicine formulas as a recognized compatible unit. However, the changes and interactions of the main components of these two formulas when paired remain unclear, and there is currently no standard or method for their...

Acta Chromatographica > 2024 > Vol. 36, no. 1 > 14--22

We developed and validated a sensitive, heart-cutting, two-dimensional liquid chromatography–tandem mass spectrometry (2D-LC‒MS/MS) method to determine the concentration of mometasone furoate in human plasma after nasal spray administration. Isotopically labeled mometasone furoate-13¹³C,d₆ was used as an internal standard (IS). Plasma samples were prepared using a solid-phase extraction (SPE) method...
