What is the importance of Rf value in chromatography? Why are trace gases important? Why is a spectrophotometer important? What are the advantages and disadvantages of simple random sampling? Why is forensic toxicology important? Why is standardization necessary in titration?
What is the importance of Rf value in chromatography? Explain how microorganisms can be harmful or beneficial to the human body. Why is heat necessary in spore staining? How do marine microorganisms affect large-scale processes on Earth?
Thin-layer chromatography also gives the basic idea for isolation because it requires proper combination of solvents for optimum Rf value. Column chromatography is the most basic technique for isolation of phyto-molecules. During isolation process both thin-layer chromatography and column chromatography ...
This is the first detailed study on diversity and ethno-medicinal uses of mushrooms from the State of Jammu and Kashmir. Methods Consecutive surveys were conducted to record ethnomycological diversity and socio-economic importance of wild edible mushrooms value chain in rural areas of Azad Jammu and...

Phytosterolic composition seems also to support the host-plant cluster of C. succinctus group because the occurrence of δ7-avenasterol in pollen is indicative of this group (Indicator Compound Analysis, p = 0.011, indicator value = 0.629) despite variation in sterolic ...
Intermediates 20–22 were obtained according to the syn- thetic routes detailed in Fig. 4. 4-Nitrobenzimidazole was treated with 2-chloro-N,N-dimethylethylamine and the obtained 4- and 7-nitro regioisomers (23 and 24, respectively) were separated by column chromatography. Then, pure 23 was...
2.3 Liquid chromatography 2.3.1 Sample preparation Sample preparation was envisaged by the work of Honda et al. [16]. Briefly, serum, urine, and gastric fluid (after being stored at −20°C) were thawed at room temperature. Then, 0.25 mL of the fluid was transferred to an Eppendorf...
What is the importance of plant anatomy? What is the importance of precipitation in climate science? Why is a spectrophotometer important? Why is cytology important in the study of zoology? What are the benefits of forensic dentistry? What is the importance of Rf value in chromatography?
A fungal strain, Penicillium purpurogenum IAM 15392, produced the azaphilone Monascus pigment homolog when cultured in a medium composed of soluble starch, ammonium nitrate, yeast extract, and citrate buffer, pH 5.0. One of the typical features of violet pigment PP-V [(10Z)-12- carboxyl-mon...
