Biogenic Synthesis and Size Distribution Analysis of Iron Nanoparticles of Fungus Penicillium crustosum, Isolated from Taxus baccata Linn| Chapter 10 | Research Advances in Microbiology and Biotechnology Vol. 5

 The study is focused on the combination and analysis of the capacity of iron nanoparticles (INPs), synthesized from Penicillium crustosum, a fungal endophyte populating in Taxus baccata Linn. After microscopic level identification, the fungal extract was assign the synthesis of Iron nanoparticles. The formation of Iron nanoparticles was habitual by SPR and UV-vis spectral study as specific peaks were acquired at 230 nm and 290 nm. The powdered form of INPs acquired after Lyophilization was assign size description using Radioactivity diffraction (XRD), place the average size was deliberate using Debye-Scherrer’s recipe and it showed the average capacity of INPs was 34.18 nm. The dynamic light scattering (DLS) and zeta potential reasoning showed that the Z average of the INPs was 424.3 r.nm, accompanying zeta potential -20.3 mV with PdI 0.688 improving polydispersity. Tools like Field issuance scanning power microscopy (FEG-SEM), and high-determination transmission power microscopy (HRTEM) were used to study the surface and size of combined INPs, here the capacity was 39.94 nm and 29.09 nm, respectively. The occupancy of elemental iron in the sample was habitual by using Strength dispersive spectroscopy (EDS). The vibrating sample magnetometer (VSM) confirmed that the made nanoparticles were ferromagnetic. This study concluded that the endophytic fungi P. crustosum maybe used as a potential lowering agent for the combination of Iron nanoparticles in a safe and economical way.

Extraction and Identification of the Taxine, Precursor of the Anticancertaxol, from the Needles of the Moroccan Yew | Chapter 10 | Current Perspectives on Chemical Sciences Vol. 1

 

The extraction of taxine, precursor of the taxol, was effected by the solution sulphuric acid from the
needles of Moroccan yew (
Taxus baccata). The extract yield was estimated at about 0,53%.
The identification of all the taxines as taxine B, isotaxine B and taxoidebasique-deacetyltaxine A by
high performance liquid chromatography HPLC and gas chromatography-mass spectrometry GC/MS
methods.

Studies of the New Taxoids from the Moroccan Yew and the Separation of the Different Fractions by Chromatography Techniques | Chapter 9 | Current Perspectives on Chemical Sciences Vol. 1

 

The extraction of the needles of the Moroccan yew (Taxus baccata) with a solution MeOH provides
the methanolic extract. The separation of the different fractions of the methanolic extract by column of silica gel made it possible to isolate two taxoids 19-Debenzoyl-19-acetyltaxinine 1 and 5-cinnamoylbrevifoliol (= 13- deacetyltaxuspine) 2. The identification of these alkaloids was established by high performance liquid chromatography HPLC and gas chromatography-mass spectrometry CG/MS methods.
