  Objective: Sarcostemma viminale (L.) R. Br. is one of the important endangered medicinal plants belonging to the family Asclepiadaceae. The aim of the present investigation was to determine the possible bioactive phytochemicals from stem of S. viminale (L.) R. Br. using methanol, chloroform, and hexane as solvents.Methods: Plant material was collected from typical conditions of Indian Thar Desert in the month of July-September, 2016. This plant always grows in association with the congeneric plant, Euphorbia caducifolia. The phytochemical compounds were investigated using Perkin-Elmer gas chromatography-mass spectrometry, while the mass spectra of the compounds found in the extract were matched with the National Institute of Standards and Technology library.Results: Maximum % area is found for Lup-20-(29)-en-3-yl acetate is present maximum amount (40.85%) with reaction time (RT)=43.787 minutes, followed by 4, 4, 6A, 6B, 8A, 11, 11, 14B-octamethyl-1, 4, 4A, 5, 6, 6A, 6B, 7, 8, 8A, 9, 10, 11, 12, 12A, 14, 14A, 14B-octadecahydro-2H-picen-3- one$$olean-12-en-3-one# (13.74%) with RT=44.420 minutes in the methanolic extract; acetic acid 4, 4, 6A, 8A, 11, 12, 14B-octamethyl-1, 2, 3, 4, 4A, 5, 6, 6A, 6B, 7, 8, 8A, 9, 10, 11, 12, 12A, 14, 14A, 14B-eicosahydro-picen-3-yl ester $$ urs-12-en-3-yl acetate is present maximum amount (44.98%) with RT=48.265 minutes, followed by. beta.-amyrin (18.51%) with RT=40.580 minutes in the chloroform extract; acetic acid 4, 4, 6A, 8A, 11, 12, 14B-octamethyl-1, 2, 3, 4, 4A, 5, 6, 6A, 6B, 7, 8, 8A, 9, 10, 11, 12, 12A, 14, 14A, 14B-eicosahydro-picen-3-yl ester $$ urs-12-en-3-yl acetate is present maximum amount (45.47%) with RT=48.514 minutes, followed by. beta.-amyrin (19.21%) with RT=40.555 minutes in the hexane extract of stem of S. viminale (L.) R. Br.Conclusion: Medicinal plants contain one or more substances that can be used for therapeutic purpose; they are used by the world population for their basic health needs. The importance of the study is to investigate the pinpoint biological activity of some of these compounds so that they can be used by pharma or some other drug designing industry to find a novel drug.

Arthrobactersp. SPG transformed indole completely in the presence of an additional carbon source. High performance liquid chromatography and gas chromatography-mass spectrometry detected indole-3-acetic acid, indole-3-glyoxylic acid, and indole-3-aldehyde as biotransformation products. This is the first report of the formation of indole-3-acetic acid, indole-3-glyoxylic acid, and indole-3-aldehyde from indole by any bacterium.

Abstract Background It is meaningful to quantify some neurotransmitters in cerebrospinal fluid (CSF) for pathology and clinical diagnosis. The objective of this study was to develop a rapid and reliable method for detecting 5-hydroxyindole ethanol (5-HTOL), 5-hydroxyindole acetic acid (5-HIAA), 5-hydroxytryptophan (5-HTP) and 5-hydroxytryptamine (5-HT) in CSF by gas chromatography-mass spectrometry (GC-MS), and explore the clinical significance of the levels of these neurotransmitters in CSF from acute lymphoblastic leukemia (ALL). Methods The levels of 5-HTOL, 5-HIAA, 5-HTP and 5-HT in CSF from children with ALL and a control (CON) group were examined by the proposed GC-MS method. Results The GC-MS method showed good sensitivity and accuracy. 5-HT and 5-HIAA contents in the ALL group were significantly lower than those in the CON group (p < 0.01), while there was no significant difference in 5-HTP and 5-HTOL contents between the two groups (p > 0.05). Conclusions This sensitive and reliable method could be used in studies focusing on clinical pathogenesis of ALL.
