In this thesis the chemical composition of heartsease (Viola tricolor L.) was studied to support the evidence-based determination of its biological activities. Henceforth, a proper sample preparationmethodwas developed, yielding a fraction rich on polar constituents (characteristic of the traditionally applied aqueous extract), which was further separated by conventional Sephadex LH-20 column c...

A new lignan glycoside, tianshanoside A (1), together with a known phenylpropanoid glycoside, syringin (2) and two known lignan glycosides, picraquassioside C (3), and aketrilignoside B (4), were isolated from the whole plant of Viola tianshanica Maxim. The structure of the new compound was elucidated by extensive NMR (1H, 13C, COSY, HSQC, HMBC and ROESY) and high resolution mass spectrometry a...

It is crucial to improve the shallot (Allium ascalonicum L.) cultivation system on peatlands increase growth and production of shallots. One provision Biostimulants derived from Kirinyuh (Chromolaena odorata extract. This study aimed determine effect (C. odorata) methanol extract yield (A. ascalonicum) best concentration application time research was conducted September December 2020 at Biology...

The development of HIV-1 protease inhibitors (HPIs) in highly active antiretroviral therapy (HAART) has dramatically decreased AIDS mortality. However, HPIs exhibit suboptimal therapeutics in vivo due to their intrinsic low oral absorption and rapid efflux via ATP-binding cassette transporters. These attributes facilitate uninhibited viral propagation and rapid selection of drug resistant HIV-1...

BACKGROUND Viola odorata L. belongs to Violaceae family and is native to Iran. It is used in the form of Almond-Violet oil in traditional Persian medicine (TPM) since ancient times. Almond-Violet oil was used for the treatment of insomnia, headache, cough, and fever based on TPM textbooks. There are two methods for the preparation of Almond-Violet oil. The first is macerating voila flowers in s...
