The efficacy of decoction in extracting mycobactericidal compounds from Flourensia cernua (Hojasé) leaves and fractionation with solvents having ascending polarity was compared with that of (i) ethanol extraction by still maceration, extraction with a Soxhlet device, shake-assisted maceration, or ultrasound-assisted maceration, followed by fractionation with n-hexane, ethyl acetate, and n-butan...

Low country live wood termite (LCLWT), Glyptotermes dilatatus is attractive to rotted stumps of tea plant, Camellia sinensis. Rotted stumps are formed due to the attack of wood rot fungi in pruned stems. The objective of the present study was to investigate the response of LCLWT to extracts of rotted and healthy stems of susceptible tea cultivars, TRI 2023 and TRI 4042 and tolerant cultivars, T...

Fruits of Pterodon pubescens Benth have been used traditionally for the treatment of rheumatism, sore throat, and respiratory disorders, and also as anti-inflammatory, analgesic, depurative, tonic, and hypoglycemic agent. The study was aimed at evaluating the anti-inflammatory activity of the hexane fraction of an ethanolic extract of P. pubescens fruits. The oil from P. pubescens fruits was ex...

Aim: The methanol extract and partitioned fractions of Cleistopholis patens leaf were evaluated for antiplasmodial activities with a view to establishing its antimalarial potential identifying the most active fraction.
 Methods: was collected, authenticated, air-dried powdered. extract, prepared by maceration in tested (0-800 mg/kg) against P. berghei mice using Peter’s four-day test. Norm...

A study of detonations in high-molecular weight hydrocarbon fuels of interest to pulse detonation engine applications was performed in a 280 mm diameter, 7.3 m long facility. Detonation pressure, wave speed, and cell width measurements were made in JP-10 mixtures and in mixtures representative of the decomposition products of JP-10. Experiments were performed in vapor-phase JP-10 mixtures at 35...

Shallots (Allium cepa L.) can not only be used as a seasoning in cooking, but also medicine by the Indonesian people. The part of plants that are tubers. Shallot tubers contain secondary metabolites, phenol, flavonoids and terpenoids have antibacterial activity. purpose this research is to know antimicrobial activity n-hexane, ethyl acetate 1-butanol fraction shallot againts Staphylococcus aure...

Matoa (Pometia pinnata) is parts of Sapindaceae family widely spread in tropical areas, especially Papua. Several studies mentioned the use its as antioxidants and contain phenolic compounds flavonoids. This study aim(s) to conduct a phytochemical screening test well cytotoxic for Pometia pinnata leaves fraction using BSLT method. The research series began with extraction process 96% ethanol, t...
