“Science without practice is dead, and practice without science is blind and dangerous.”
Mykola Ovksentiyovych Valiashko
(March 20, 1871 – January 25, 1955). 84 years
Mykola Valiashko is a seminal figure who effectively transformed Ukrainian pharmacy from a craft-based “herbalism” into a fundamental academic science. As the first rector of the Kharkiv Pharmaceutical Institute, he served as a bridge between classical pharmacognosy and pharmaceutical chemistry.
Key Biographical Milestones
Origin and Early Career: Born on April 1, 1871, in Kupiansk into the family of a pharmacist (provisor). He progressed from an apprentice in his father’s pharmacy to a world-renowned scientist. Education: Graduated from Kharkiv University (having completed both pharmaceutical courses and the natural sciences department). He underwent advanced research training in leading German laboratories, including those of Walther Nernst and Emil Abderhalden, which enabled him to introduce the most advanced analytical methods to Ukraine. Institutional Development: In 1921, he initiated the establishment of the first specialized higher education institution for pharmacy in Ukraine – and one of the first in Europe – the Kharkiv Pharmaceutical Institute (now the National University of Pharmacy, NUPh).
Scientific Contribution – A Revolution in Pharmacognosy
Mykola Valiashko’s primary scientific achievement was the implementation of physicochemical methods into the study of medicinal plant materials. In an era when molecular structures were predominantly determined through complex chemical transformations, Valiashko demonstrated the efficacy of absorption spectroscopy in the ultraviolet region. He was the first in the world to apply ultraviolet (UV) spectroscopy to elucidate the structure of organic compounds of plant origin. He established the correlation between absorption spectra and the chemical structure of benzene derivatives, which allowed for the identification of essential oil components and other plant extracts with unprecedented precision for that time. Key Research Objects: –Flavonoids (Rutin and Quercetin): In his 1904 Master’s thesis, he proved the structure of the glycoside rutin, isolated from Ruta graveolens. –Cardiac Glycosides: He investigated the chemistry of pheasant’s eye (Adonis vernalis). –Anthraglycosides: He studied the active components of alder buckthorn (Frangula alnus). –Essential Oils: He analyzed the composition of Ukrainian essential oil raw materials, establishing the standards for future pharmacopoeias.
Pedagogical and Public Activity
Mykola Valiashko established the “Kharkiv School” of pharmacists, founded on the principle of the inseparable connection between the study of medicinal raw materials and their molecular structure.
Under his leadership, the standards for the first State Pharmacopoeias were developed, and Kharkiv was transformed into the primary center of pharmaceutical thought in Eastern Europe.
Selected quotations of M.O. Valiashko, highlighting his role as a reformer who transitioned pharmacy from a craft to a fundamental science, and reflecting his perspective on the scientist’s duty to society and the future
“Pharmacy is not merely the art of compounding medicines; it is, above all, an exact chemical science that demands rigorous analytical thinking and flawless precision in execution”.
“A true pharmacist must see the human life behind every molecule, and the progress of national science behind every research study”.
“University walls provide only the foundation, but a pharmacist must construct the true edifice of their knowledge throughout their entire life through independent labor”.

MELON The fruits of the melon (Cucumis melo) exhibit a relatively limited vitamin profile, with the exception of ascorbic acid (22.0% of the Daily Value [DV] per 100 g). However, the fruit is characterized by a significant concentration of specific mineral elements: silicon (273.0% DV per 100 g), rubidium (77.0%), cobalt (20.0%), boron (16.7%), vanadium (10.0%),…
BUTTER MUSHROOMS Butter mushrooms (Suillus spp.) exhibit a rich vitamin profile, notably: nicotinic acid (vitamin PP) (33.0% of the Daily Value [DV] per 100 g), ergocalciferol (vitamin D2) (26.0%), pyridoxine (15.0%), and riboflavin (14.3%). They are also characterized by a significant concentration of mineral elements: rubidium (225.8% DV per 100 g), copper…
CRANBERRY Cranberry (Vaccinium oxycoccos or Vaccinium macrocarpon) serves as a source of ascorbic acid (15.0% of the Daily Value [DV] per 100 g), alpha-tocopherol (8.0%), and riboflavin (7.5%). It is further distinguished by its mineral profile, containing significant macro- and microelements: boron (171.0% DV per 100 g), rubidium (44.0%), manganese (19.5%), vanadium (14.9%), cobalt (14.4%), nickel…
Iod (I) For the plant: immunity. The absorption of iodine by plants depends on the content of its compounds in the soil and the species of the plant. In the plant organism, iodine plays an important role in the synthesis of certain…
DRIED APRICOTS Kuraga is one of two types of dried apricots, namely dried apricots with the pits removed beforehand. The second type of dried apricots is uruk – apricots (usually small-fruited sweet varieties) dried with the pits, most often simply on the tree in the sun (after drying, they are shaken off)….
ZUCCHINI Zucchini (Cucurbita pepo ssp. pepo) is characterized by a significant concentration of the carotenoids lutein and its isomer zeaxanthin (35.4% of the Daily Value [DV] per 100 g). These xanthophylls possess the capacity to accumulate within ocular tissues, providing essential photoprotection and supporting visual acuity. Its nutritional and mineral profile is notably rich…
