Solar geoengineering has been proposed as a method of meeting climate objectives, such as reduced globally averaged surface temperatures. However, because of incomplete understanding of the effects of geoengineering on the climate system, its impleme

A dichloromethane extract of the triterpenoids from seeds of the Neem tree (Azadirachta indica) can be fractionated rapidly and with economic use of solvents using the Biotage™ flash chromatography system. The fractions can be analysed by thin laye

The natural insecticide azadirachtin is most stable in mildly acidic aqueous solutions between pH 4 and 6 at room temperature. It is unstable in mildly alkaline and strongly acidic solutions. It is stable when stored in neutral organic solvents at ro

Journal of Chemical Ecology. 23:2841-2860
Nimbin and salannin, major triterpenoids accompanying azadirachtin in extracts of neem (Azadirachta indica) seeds, were photooxidized by UV light in the presence of oxygen to more polar, unstable intermediates that rearranged on silica gel to two fin

Supercritical fluid extraction (SFE) of plant materials began with industry and moved to the laboratory, along with supercritical-fluid chromatography, as high pressure systems became available. SFE has been applied to several groups of non-polar com

The natural insecticide azadirachtin (1) has been isolated from dried cells of the Neem tree (A. indica) grown in tissue culture on a synthetic medium and shown chemically to be identical with the compound isolated from the seeds of the Neem tree, by

Photo-oxidation of the neem limonoids nimbin and salannin with UV light in the presence of oxygen gives two isomeric lactone products per limonoid, nimbinolide and isonimbinolide, and salanninolide and isosalanninolide, respectively. When compared in

Using stable isotope-labelled probes and mass spectrometry, the insect pheromone (S)-4-methyl-3-heptanone is shown to be biosynthesised from three propionate units following a polyketide/fatty acid-type metabolic route.
