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). 

Convolvulaceae. Castasterone (C g) and 28-norcastasterone (C ), both characterized by a 2a,3a-dihydroxy residue, were identified in the seeds of Ipomoea purpurea (L.) Roth sub nom. Pharbitis purpurea (L.) Voigt (Suzuki et al. 1985).
