2. High resolution LC-MS/MS screening for secondary metabolites in bulgarian species of genus Astragalus L
The phytochemical content of some Astragalus species distributed in Bulgarian flora has been previously studied. Among other compounds, flavoalkaloids, acylated flavonoids, flavonoid triglycosides and cycloartane saponins have been isolated so far. The composition of the rest of the representatives of this genus in Bulgaria is not explored yet. The aim of th

5. REAL TIME PPP APPLIED TO AIRPLANE FLIGTHT TESTS
Abstract The availability in real time of GNSS satellites orbits, clock corrections and code and phase biases provided the possibility of application of Real Time Precise Point Positioning (RTPPP). This paper presents the methodology concerning RTPPP and application to kinematic trajectories of airplane flight tests, but without using the carrier phase bias.

6. Simultaneous determination of five N-alkylamides in the root of Anacyclus pyrethrum by HPLC and profiling of components in its methanolic root extract by UPLC/Q-TOF-MS
ABSTRACT The root of Anacyclus pyrethrum (L.) Lag., Asteraceae, is very widely used for treating various diseases in Traditional Uygur Medicine, particularly in the treatment of vitiligo. However, there have been few studies on the quality standards of A. pyrethrum in China. A. pyrethrum contains abundant N-alkylamides, which are considered to be the princip

8. Pharmacokinetics of oleracimine in rats by ultra-high-performance liquid chromatography
The novel alkaloid, oleracimine, presented remarkable anti-inflammatory bioactivity, and therefore, its pharmacokinetics was investigated in rat plasma after intravenous and oral administration by using a rapid ultra-high-performance liquid chromatography (UHPLC) method with UV detection at 270 nm. The analysis was performed on a shim-pack ODS column (75 mm�

10. Cytotoxicity of hydroxydihydrobovolide and its pharmacokinetic studies in Portulaca oleracea L. extract
ABSTRACT Hydroxydihydrobovolide (HDB) was for the first time isolated from Portulaca oleracea L. and then its cytotoxicity against SH-SYTY cells was studied. Moreover, a rapid and sensitive ultra-high performance liquid chromatographic (UHPLC) method with bergapten as internal standard (IS) was developed and validated to investigate the pharmacokinetics of H
