The total phenol content and the anti-acetylcholinesterase activity were compared in olive leaf (OL) extracts obtained using both subcritical water extraction (SbWE) conventional solvent (ethanol-water). method proposed by Ellman (in vitro) was used to study inhibitory of acetylcholinesterase (AChE). phenolic compounds AChE activities OL varied depending on method. Thus, extract technique (220 ...

O experimento foi instalado em área renovação canavial, localizada Campina Verde – MG, na safra 2021/22. delineamento experimental utilizado blocos casualizados, quatro repetições. Os tratamentos foram cinco rasteiro, sendo uma cultivar (BRS 423 OL) e linhagens (2717 OL, 2173 2094...

The COVID-19 pandemic has forced universities to make a radical switch from face-to-face traditional teaching (TT) completely online learning (OL). Thus, many studies proposed the proper OL environment for specific subject and evaluated its effectiveness. However, few have empirically compared with TT determine which better More importantly, an self-regulated (SRL) ability of student interactiv...

The biotransformation of partheniol by the fungus Calonectria decora ATCC 14767, produced six metabolites. These metabolites are; aromadendr-1(10)-en-8alpha -ol; 5(9),6-tricyclohumul-1(10)-en-8alpha-ol; 4,15-didehydro-6-bicyclohumulan-8a,10alpha-diol; 5(9),6-tricyclohumulan-4a,8alpha-diol; maalian-la,8alpha-diol and 14-epi-1(4)-epoxymaalian-8alpha-ol. The identities of these metabolites were es...

Three new triterpenoid aglycones named Philinopgenin A (1), B (2), and C (3) were isolated from the acid hydrolysate of the crude glycoside mixture prepared from the whole sea cucumber Pentacta quadrangulasis Lesson. The corresponding structures were determined as 16β-acetoxyholosta-8(9), 24(25)-diene-3β-ol (1), 20, 25-epoxy-lanosta-9(11)-ene-3β-ol 18(16)–lactone (2) and 16β-acetoxyholosta-9(11...

The essential oils from rhizomes of Rhodiola crenulata and R. fastigiata in eastern Tibet were analyzed by using GC-MS. The major constituents were geraniol (53.3%), n-octanol (13.4%), 2-methyl-3-buten-2-ol (10.8%), citronellol (5.3%), 3-methyl-2-buten-1-ol (4.0%), myteol (3.0%), and linalool (2.4%) for R. crenulata and geraniol (45.3%), n-octanol (12.3%), 2-methyl-3-buten-2-ol (8.0%), linalool...

A simplified method is described for the preparation of 14 alpha-hydroxymethyl-4,4-dimethyl-5 alpha-cholest-8-en-e beta-ol, 14 alpha-hydroxymethyl-4,4-dimethyl-5 alpha-cholest-7-en-3 beta-ol, and 14 alpha-hydroxymethyl-4,4-dimethyl-5-alpha-cholest-6-en-3 beta-ol from commercial lanosterol. This method represents a modification of the approach introduced by Fried and co-workers (Fried, J., J. W....

Relationships between fish length and otolith length, width mass were investigated in the two nearly threatened silurid species (Siluriformes) Ailia coila (Hamilton, 1822) Ompok pabda Hamilton, collected from Ganga River at Narora, India. The relationships (OL) total (TL), (OWd) TL, weight (OWe) TL are expressed by linear regression models; for A. coila, OL = 0.0291 + 0.8541, OWd 0.0306 0.2241,...

the volatile constituents of the aerial parts of vervain (verbena officinalis l.) cultivated locally were investigated. analysis of the volatile fraction by gc and gc-ms is described. compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).
