Patel, Rajani published the artcileGas chromatography-mass spectrometry analysis of chemical components of two different stages of root part of moolak (Raphanus sativus Linn.), SDS of cas: 177-10-6, the publication is International Journal of Research in Ayurveda & Pharmacy (2021), 12(2), 11-14, database is CAplus.

Moolak or Radish (Raphanus sativus Linn.) is grown all over the world. Radish is eaten raw as salad due to its pungent flavor. Tender radish root is consumed with leafy vegetable and radish in its starting stage of bolting is consumed as stew. After late bolting stage, only new leaves produced in inflorescence axis and seeds are consumed as edible substance and mature seeds are used for medicinal purpose like Kushtha (Skin disease). Formulations of Moolak seed is already mentioned in Ayurvedic literatures. Here we are taking tender and early bolt stage of radish where tender is balmoolak and Bolt is vriddha moolak. This study shows the differences in chem. composition of two stages of moolak to know about their medicinal properties, because medicinal properties of herbs are due to phytoconstituents. GC-MS (Gas chromatog.-mass spectrometry) technique is used to identify bioactive compounds in methanolic extract of Raphanus sativus. Tender radish (balmoolak) has shown total 38 peaks and Bolt radish (vriddhamoolak) showed total 41 peaks of phytoconstituents. 15 compounds are common among both samples.

Gladvin, G. published the artcileStudy Of active constituents from methanolic extract of watermelon fruit extract a comparative analysis of hybrid and wild cultivar, Formula: C6H12O2, the publication is Research Journal of Pharmaceutical, Biological and Chemical Sciences (2020), 11(5), 117-123, database is CAplus.

Plants are rich in active bio-mols., and these mols. synthesized as secondary metabolites for a wide range of physiol. functions, including defense and food reserve. These plant phytochems. belong to a wide range of categories, including steroids, alkaloids, phenolic compounds, terpenes, saponin, and resin, etc. Watermelon is fruit for the richest source of various bio-active compounds, including vitamins and minerals. Over a period of time numerous hybrid cultivars were designed for com. and large scale cultivation of watermelon. The key question arises among scientific platform for the active phytochems. present in the watermelon hybrid cultivar over wild type. The present study was aimed to carry out a comparative anal. of the presence of various active biomols. in watermelon Citrulus Lanatus hybrid and wild type. We have extracted active phytochems. using multiple solvents, including methanol, acetyl acetate, and chloroform. The methanolic extract was further characterized for active phytochems. using GC-MS for both hybrid and wild type cultivar. Based on phytochem. anal. and preliminary activity anal., i.e., the antimicrobial and antioxidant methanolic extract does possess a comparatively higher biol. activity and hence active biomols. The GC-MS anal. shows a wide range of phytochems., including Alkaloids, Phenolic compounds, Saponin, Quinone, and Coumarin in methanolic extract On the contrary, methanolic extract of wild type cultivar does possess flavonoid, saponnin and steroid, phenolic acids and glyco-conjugates, flavonoids and glyco-conjugates, metabolites of phenylpropanoid pathway, such as gingerol, cinnamic acid, p-coumaric acid, etc.; organic acids such as citric acid, iso-citrate, fumarate, etc.; carotenoid such as beta-carotene metabolism products, curcuminoids; curcubitacin E, monosaccharaides and oligosaccharides, amino acids such as Citrulline, saturated mono and polyunsaturated fatty acids, and compound lipids such as Ceramide and Sphinganine; nucleotide bases such as guanosine, uridine, etc. The study shows watermelon hybrid cultivar are rich in diverse phytochem. over wild type cultivar precisely methanolic extract

Alvarez-Martin, Alba published the artcileInvestigation of volatile organic compounds in museum storage areas, Application of 2,2,4-Trimethyl-1,3-dioxolane, the publication is Air Quality, Atmosphere & Health (2021), 14(11), 1797-1809, database is CAplus.

This study investigates the complex mixture of volatile organic compounds (VOCs) released by and accumulated within a collection of historic medicinal, pharmaceutical, and cosmetic artifacts housed at the National Museum of American History (Smithsonian Institution). In recent years, staff have become concerned, both for the safety of the objects and for personnel working in the collection, about strong unremediated odors accumulating within several storage cabinets. Museum staff also wondered if non-odorous off-gassing might need remediation. Solid-phase microextraction combined with gas chromatog.-mass spectrometry anal. (SPME-GC-MS) was used to identify VOCs present in the storage room housing the collection. Over 160 compounds were detected and identified overall. Among these, 49 appeared to be directly related to ingredients used in the manufacture of many collection items. The results of the study suggest that SPME-GC-MS can be a strong tool for the rapid screening of multicomponent museum collections exhibiting off-gassing problems, before the pursuit of other more tedious anal. approaches. Addnl., the study reveals valuable insight into the characteristic volatile emission of historic medicinal, pharmaceutical, and cosmetic artifacts, increasing understanding of, and decision-making for, similar collections of objects. Eventually, it is hoped that this information can be used to inform mitigation strategies for the capture and reduction of VOCs in collections storage areas.

Wang, Xianhua published the artcileComparative study of wet and dry torrefaction of corn stalk and the effect on biomass pyrolysis polygeneration, Application In Synthesis of 1193-11-9, the publication is Bioresource Technology (2018), 88-97, database is CAplus and MEDLINE.

Wet torrefaction (WT) possesses some advantages over dry torrefaction (DT). In this study, a comparative anal. of torrefied corn stalk from WT and DT was conducted along with an investigation of their pyrolysis properties under optimal conditions for biomass pyrolysis polygeneration. Compared with DT, WT removed 98% of the ash and retained twice the amount of hydrogen. The impacts of DT and WT on the biomass macromol. structure was also found to be different using two-dimensional perturbation correlation IR spectroscopy (2D-PCIS). WT preserved the active hydroxyl groups and rearranged the macromol. structure to allow cellulose to be more ordered, while DT removed these active hydroxyl groups and formed inter-crosslinking structures in macromols. Correspondingly, the bio-char yield after WT was lower than DT but the bio-char quality was upgraded due to high ash removal. Furthermore, higher bio-oil yield, higher sugar content, and higher H₂ generation, were obtained after WT.
