A Fourier transform infrared (FT-IR) spectrometric method was developed for the rapid, direct measurement of diosmin in different pharmaceutical drugs. Conventional KBr-spectra were compared for best determination of active substance in commercial preparations. The Beer-Lambert law and two chemometric approaches, partial least squares (PLS) and principal component regression (PCR+) methods, were tried in data processing.

The chemical constituents of Dracocephalum tanguticum were investigated using normal-and reverse-phase silica gel column chromatography, RP-HPLC, and other separation techniques, combined with experimental methods such as NMR, UV, IR, MS, and ORD, as well as comparison with reported literature data. From the ethanol extract of D. tanguticum, 10 compounds were isolated and identified: dracotangusion C(1),(1R,4S,5S,10R)-(+)-germacrone-1(10)-4-diepoxide(2), 1β,4β,5β-trihydroxy-7(11),9-germacradien-8-one(3), curcumadione(4), β-sitosterol(5), lilacoside(6), diosmetin-7-O-β-D-glucopyranoside(7), diosmin(8), luteolin-7-O-glucoside(9), and luteolin(10).

Background: Venotonics are a class of therapeutically active molecules that have vaso-protective effects. They are used to alleviate venous diseases and disorders, particularly venous insufficiency. We compared the composition of prescription versus over-the-counter (OTC) venotonics using high-performance liquid chromatography with UV detection (HPLC-DAD) and simulating their digestion using a static digestive model.
