Abstract
Dihydroquercetin (DHQ) is a bioflavonoid with high antioxidant, capillary-protective, and anti-inflammatory activity. DHQ has previously been used for treating Middle East respiratory syndrome coronavirus (MERS-CoV) infection and is currently considered a potential regulator of oxidative stress as part of COVID-19 multipurpose therapy. DHQ has a high safety profile but low bioavailability that limits its use. Innovative techniques (liposomization, crystal engineering, etc.) can be used to increase its bioavailability.

Abstract
A large amount of the current literature dedicated to solid states of active pharmaceutical ingredients (APIs) pays special attention to polymorphism of flavonoids. Taxifolin (also known as dihydroquercetin) is an example of a typical flavonoid. Some new forms of taxifolin have been reported previously, however it is still unclear whether they represent polymorphic modifications. In this paper, we tried to answer the question about the taxifolin polymorphism. Taxifolin microtubes and taxifolin microspheres were synthesized from raw taxifolin API using several methods of crystal engineering. All forms were described with the help of spectral methods, scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), and thermal analysis (TA). SEM reveals that the morphology of the solid phase is very specific for each sample. Although XRPD patterns of raw taxifolin and microtubes look similar, their TA profiles differ significantly. At the same time, raw taxifolin and microspheres have nearly identical thermograms, while XRPD shows that the former is a crystalline and the latter is an amorphous substance. Only the use of complex analyses allowed us to put the puzzle together and to confirm the polymorphism of taxifolin. This article demonstrates that taxifolin microtubes are a pseudopolymorphic modification of raw taxifolin.

Abstract
Taxifolin, also known as dihydroquercetin, is the major flavonoid in larch wood. It is well known as an antioxidant and a bioactive substance. Taxifolin as an active pharmaceutical ingredient is produced industrially in crystalline form during the processing of larch wood. Some information is available on nano- and microstructured particles of taxifolin. This paper reports on the generation of a new form of taxifolin as microtubes. These self-assembled tubes were obtained from raw taxifolin by crystal engineering with urea at ambient temperature and pressure. The parameters of temperature, pH value, molar ratio of taxifolin and urea, and time duration were optimized for yield enhancement of the microtubes. The water solubility and melting point of the new form of taxifolin were established. The microtubes were characterized by X-ray diffraction, X-ray powder diffraction, microscopy, mass spectrometry, 1H NMR spectroscopy, UV spectroscopy and Fourier transform infrared spectroscopy methods. The experimental results demonstrate that the microtubes and raw taxifolin both exist in crystalline form with the same structure of the crystal unit. However, they are characterized by different morphological and physicochemical properties. Computer simulation was performed to explain the mechanism of the self-assembly process.
