Abstract A phytochemical study of the rhizome essential oils four different Hedychium species was performed by means GC and GC/MS analyses. H. ellipticum mainly contained 1,8‐cineole, sabinene, terpin‐4‐ol, while aurantiacum possessed para ‐cymene, bornyl acetate as major entities. Similarly, trans‐meta ‐mentha‐2,8‐diene linalool were noticed in coronarium. Three collections ( I – III ) spicatum showed amazing differences relative contents their oils, 1,8‐cineole 10‐epi‐ γ ‐eudesmol being...

The chemical composition of hydro-distilled essential oil from rhizomes Curcuma amada was analysed. Nineteen compounds representing 77.31% the total were identified by GC and GC-MS. Rhizomes extracted various solvents with different polarities using antioxidant assay systems. petroleum ether extract showed potent DPPH radical scavenging activities (IC50 = 18.98 ± 0.05) reducing power (A700 0.861 0.001). Ethyl acetate exhibited remarkable nitric oxide activity (IC 50 5.97 0.09) higher than...

Three new phytoecdysteroids, ajugacetalsterones C (1) and D (3) breviflorasterone (2), were isolated from the roots of Ajuga macrosperma var. breviflora along with five known compounds, namely, 20-hydroxyecdysone, cyasterone, makisterone A, 20-hydroxyecdysone 3-acetate, 2-acetate. The structures 1−3 elucidated on basis extensive 1D 2D NMR spectroscopic studies. compounds possess acetal oxygen bridges between C-26 C-20/C-22, or C-26/C-23, a lactone bridge C-23.
