We have synthesized a tritiated form of 2,22-dideoxyecdysone -3β,14α,25-trihydroxy-5β-cholest-7-en-6-one> of high specific activity (2.2 TBq/mmol).We have examined the capacity of various endocrine (prothoracic glands, follicle cells) and peripheral (fat body, Malpighian tubules) tissues of Locusta migratoria to use this molecule as a precursor of ecdysone biosynthesis.Efficient conversion of 2,22-dideoxyecdysone to 2-deoxyecdysone and to ecdysone could principally be monitored in the prothoracic glands and follicle cells.

Nine compounds (1-9) have been isolated from the whole plants of Paris verticillata M.v.BIEB. (Liliaceae) and their structures characterized.They can be divided into four groups; phytosteryl derivatives (I, phytosteryl (6'-palmitoyl)-β-D-glucopyranoside; 2, the despalmitate of 1), phytoecdysones (3, ecdysone; 4, ajugasterone A; 5, ecdysterone), pennogenin glycosides (6, pennogenin tetraglycoside (T-g); 7, prototype glycoside of 6), and kaempferol glycosides (8, kaempferol 3-O-α-L-rhamnopyranosyl-(1->2)-β-D-glucopyranoside; 9, 7-O-β-D-glucopyranosyl kaempferol 3-O-α-L-rhamnopyranosyl-(1->2)-β-D-glucopyranoside).Keywords: Paris verticillata; Liliaceae; phytosteryl (6'-palmitoyl)-glucoside; ecdysone; ajugasterone A; ecdysterone; pennogenin glycoside; furostanol glycoside; kaempferol glycoside
