Simple gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) methods were developed for quantifying eight volatile compounds and 10 sesquiterpenoids, respectively. GC-MS analysis was performed on an HP-5MS capillary column (30 m×0.25 mm i.d.) coated with 0.25 μm film 5% phenyl-95% methylpolysiloxane and selected ion monitoring was used for quantification...

Dietary administration of the monocyclic monoterpenoid d-limonene causes complete regression of both dimethylbenz[a)anthraceneand Vnitroso-/V-methylurea-induced rat mammary carcinomas. Carcinomas regress when limonene is added to the diet either when the tumor is small and still capable of spontaneously regressing or when it is large and progressed beyond the stage when it is susceptible to spo...

Phytochemical investigation of the seeds Pentaclethra macrophylla led to isolation a mixture two new aromatic monoterpene glycosides, pentamacrophylloside A (1a) and B (1b), together with six known secondary metabolites: Comososide (2), secopentaclethroside (3), caffeoylputrescine (4), β-sitosterol-3-O-β-D-glucopyranoside (5), 2-hydroxymethyl-5-(2-hydroxypropan-2-yl)phenol (6), sucrose (7). The...

Abstract: Background: Recently, emulgel has emerged as a potential hydrophobic drug delivery method. Therefore, this study aims to evaluate the phytochemical content of Oryza sativa extract and develop an formulation using Carbapol 940 gelling agent. Materials Methods: The emulsion was placed in gel basis after preparation formulations were evaluated for their rheology, pH, spreading coefficien...

Background: The development of serum preparations containing natural ingredients for sun protection is growing rapidly. Jamblang (Syzygium cumini) leaves are rich in phenolic compounds that can inhibit free radicals causing premature aging. Therefore, this study aims to determine the potential S. cumini extract as protection. Methods: was prepared and included base. formulations were evaluated ...

BACKGROUND Aedes aegypti L. is the major vector of dengue fever and dengue hemorrhagic fever. In an effort to find effective tools for control programs to reduce mosquito populations, the authors assessed the acute toxicities of 14 monoterpenoids, trans-anithole and the essential oil of rosemary against different larval stages of Ae. aegypti. The potential for piperonyl butoxide (PBO) to act as...

Insecticidal activity of essential oil extracted from Morinda lucida was tested on pulse beetle Callosobruchus maculatus, which is a pest that causes serious damage to several pulses. The insecticidal activity was compared with two pesticides, Phostoxin and Primo-ban-20. 120 mixed sex adult C. maculatus were introduced, along with 30 g of cowpeas. Four concentrations (0.40, 0.20, 0.10, and 0.05...

Neglected Tropical Diseases (NTDs), like leishmaniasis, are major causes of mortality in resource-limited countries. The mortality associated with these diseases is largely due to fragile healthcare systems, lack of access to medicines, and resistance by the parasites to the few available drugs. Many antiparasitic plant-derived isoprenoids have been reported, and many of them have good in vitro...

The essential oil of catnip, Nepeta cataria (Lamiacae) was evaluated for behavioral effects on two populations of subterranean termite, Reticulitermes flavipes (Kollar) and R. virginicus (Banks) (Isoptera: Rhinotermitidae). The catnip essential oil contained approximately 36:64 E,Z-nepetalactone and Z,E-nepetalactone, respectively. The time to 50% dissipation (DT50) of the isomers in sand was d...

Purpose: To determine larvicidal activity of the essential oil derived from Illicium henryi Diels (Illiciaceae) leaf and stem against the larvae of Aedes albopictus Skuse. Methods: The essential oil of I. henryi leaves was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromaotography-mass spectrometry (GC-MS). The activity of the oil was evaluated, using World He...
