Microstructure of Salicornia bigelovii Stems Under Photonic and Electron Microscopy

Triterpenoids from the Herbs of Salicornia bigelovii.

A new nortriterpene saponin, 3-O-β-d-glucuronopyranosyl-30-norolean-12,20(29)-dien-23- oxo-28-oic acid, namely bigelovii D (11), was isolated from the hydroalcoholic extract of herbs of Salicornia bigelovii along with 10 known saponins (1-10). Their chemical structures were identified on the basis of spectroscopic analyses including two-dimensional NMR and a comparison with literature data. Som...

Isolation, identification and cytotoxicity of a new noroleanane-type triterpene saponin from Salicornia bigelovii Torr.

Salicornia bigelovii Torr. has been consumed not only as a popular kind of vegetable, but also as a medicinal plant to treat hypertension, cephalalgia, scurvy and cancer. The present study was designed to investigate its chemical components and cytotoxic activity. A new noroleanane-type triterpene saponin, bigelovii C (1), was separated and purified from Salicornia bigelovii Torr., along with f...

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy

Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...
