A comparison of the efficiency of the 2,3-oxidosqualene cyclase from human placenta microsomes with that from rat liver microsomes has led to the conclusion that in human placenta the conversion of squalene into lanosterol is limited by the rate of squalene epoxidation. Tracer from [l- C]-2,3-oxidosqualene was incorporated into cycloartenol (1% yield) by a cell-free system from Alnus glutinosa but none of the triterpenoid glutinone was synthesized from the labelled precursor. When 2,3-oxidosqualene was incubated with cell-free extracts from corn embryos the only product was cycloartenol, whereas when l-trarts-T-nor-2,3-oxidosqualene (9) was the substrate both 31-norcycloartenol and 31-norlanosterol were formed " l-c/s-T-nor-2,3-oxidosqualene (10) gave rise to no detectable cyclization products... 

A combination of the rice lamina inclination assay and GC/MS or GC/SIM analyses have allowed for identification of the brassinosteroids in various plant tissues These include brassinolide, 6-deoxodihydrocastasterone, brassinone from the insect galls of Castanea crenata (18,20) castasterone and 6-deoxodihydrocastasterone from the stems, leaves and flowers of Castanea crenata (20) brassinolide, castasterone, typhasterol (7), and teasterone (8) from leaves of Thea sinensis (21-23) castasterone and brassinone from the fruit of Pharbitis purpurea ( Japanese morning glory ) (24) brassinolide, castasterone and 24-epibrassinolide(29) from immature seed and/or pollen of Vida faba (broad bean ) (25,26) brassinolide and castasterone from the pollen of Alnus glutinosa (European alder) (27). 

An alternative highly sensitive technique by GC/MS is that of tandem MS or MS/MS. In this technique, the first mass filter is used to select the ion of interest from all the other ions produced from the matrix. This ion is usually the molecular ion in the El mode or the protonated molecule (MH+) in the Cl mode. These selected ions then undergo collisionally activated dissociation to produce daughter ions which are then separated by a second mass filter and analyzed. The GC/MS/MS has been applied to identification of BRs in the pollen of European alder, Alnus glutinosa (L.) Gaertn.
