“…However, the compound has been reported for antioxidant properties (Kmiecik et al, 2011). Oleic acid, eicosyl ester is a monounsaturated omega-9 fatty acid, that has been reported for having mosquito repellent activity (Gurunathan et al, 2016). The FT-IR spectrum depicted a large parabola-shaped peak observed at 3184 cm -1 with aromatic C-H stretching, vibrations, with weak intensity representing the presence of Coumaric acid, aliphatic compounds (Fachriyah et al, 2019).…”

“…However, alkane stretching indicated the presence of steroids, tannins, saponins. The peak at 2413 cm -1 with medium intensity showed O-H (Carboxylic acid), which indicates the presence of Coumaric acid, Chlorogenic acid, and ferulic acid (Gurunathan et al, 2016). The peak at 1657 cm -1 with strong intensity showed C=O (Carboxylic group) with stretching vibration, which demonstrated Quercetin, Coumaric acid, and ferulic acid (Gurunathan et al, 2016).…”

The objective of the present study was to analyse the bioactive compounds of the leaves of Conocarpus lancifolius (C. lancifolius). The GC-MS analysis of the hot methanolic extract of the leaves (HMEL) of C. lancifolius exhibited the bioactive compounds such as 1-(3-Methoxy-2-nitrobenzyl) iso quinoline, morphin-4-ol-6,7-dione, 1-bromo-N-methyl-, phytol, hexadecanoic acid, 2,3-dihydroxypropyl ester, 2,2':4',2”-terthiophene, ethyl iso-allocholate, caryophyllene oxide, campesterol, epiglobulol, cholestan-3-ol, 2-methylene-, (3á,5à)-, dasycarpidan-1-methanol, acetate (ester) and oleic acid, eicosyl ester. The FT-IR analysis of HMEL of C. lancifolius showed a unique peak at 3184, 2413, 1657 cm-1 representing coumaric acid, chlorogenic acid and ferulic acid. The HMEL of C. lancifolius was actively inhibiting the proliferation of breast cancer cells MCF-7 ATCC at the concentration of 72.66 ± 8.21 µg/ml as IC50 value. The HMEL of C. lancifolius also revealed a good spectrum of activity against Gram-positive and Gram-negative bacterial cultures screened in this work. The activity observed has shown more or less similar effects against screened bacteria. However, the magnitude of potentiality was significantly lesser compared to standard ciprofloxacin disc at p< 0.001 level (99% confidence intervals). Furthermore, the study demonstrating the bioactive compounds can be isolated from the leaves of C. lancifolius.

The article is devoted to the modernization of economic development of the Baikal region. The directions of formation of innovative bioresource potential with the use of local plant raw materials are revealed. The biotechnological potential of promising medicinal plants of the genus Thalictrum L. has been studied. The content of microelements and triterpene saponins with cytotoxic and contraceptive properties in plant raw materials from natural and cultivated populations was determined. The data on productivity of Thalictrum minus in culture are presented. Accumulation of biologically active substances according to age states is studied. Morphological characteristics of individuals by years of cultivation are shown. The peculiarities of the species growth in agroculture are described. The attention is paid to the formation of productive features. Phenological spectra allowing to determine the terms of phytomass harvesting are compiled. The possibility of using cell cultures of Thalictrum L. as a source of guaranteed standardized raw materials for pharmaceutical purposes is considered.

Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible polymers that are produced by microorganisms as storage materials under limited nutrition and excess carbon. These PHAs have been found to be ideal for replacing synthetic plastics for use in packaging and biomedical applications. In this study, an alkaliphilic and moderately halophilic bacterium Halomonas alkalicola Ext was isolated from Lake Simbi Nyaima in western Kenya and investigated for PHA production. Sudan Black B and Nile Red A staining showed that bacterium had distinct ability for accumulation of PHAs. To optimize PHA production, the bacterium was grown in submerged fermentation under varying culture conditions and different sources and concentrations of carbon and nitrogen. With one-factor-at-a-time (OFTA) approach, optimal PHA yields were obtained after 72 hours at a pH of 10.0, temperature of 35°C, and 2.5% (w/v) NaCl. The bacterium yielded the highest biomass, and PHA amounts on 2% galactose and 0.1% ammonium sulfate as sources of carbon and nitrogen, respectively. A record PHA yield of 0.071 g g-1 with a titer of 1.419±0.09 g/L was achieved from 3.397 g/L of biomass, equivalent to 41.8% PHA content. Using response surface methodology, PHA titer was increased by 1.5% to 1.44 g/L, while PHA content was improved 1.1-fold to 45.57%. Polymer analysis revealed that the extracted PHA was a poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) (3−HB:3−HV=92:8) with two copolymer subunits of 3-hydroxyvaryrate (3-HB) and 3-hydroxybutyrate (3-HV). Halomonas alkalicola Ext attained efficient galactose conversion into PHBV under high salinity and alkalinity conditions.
