Triterpene glycosides of plants of the family Caryophyllaceae

In this review, tables of 25 glycosides are given and the previously unknown structures of 11 of them are established. Characteristic features of the glycosides of the family Caryophyllaceae are considered. Methods are shown for isolating the glycosides and, using acanthophylloside B — a compound having carbohydrate chains of complex structure — as example, methods of determining their structures are demonstrated.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Terpenoids and related compounds from plants of the family Compositae (Asteraceae)

This review will summarize the authors' studies on the structures of terpenoids and related compounds from plants of the family Compositae (Asteraceae). Eighty three new compounds have been obtained and characterized from seven species of the plants, namely, Erigeron annuus (L.) Pers., Erigeron philadelphicus L., Erigeron sumatrensis Retz, Ligularia dentata Hara, Ligularia stenocephala Matsum. et Koidz., Petasites japonicus Maxim. and Tussilago farfara L.     

The oils of some plants of the family Malvaceae

Summary 1. The physical and chemical properties and the fatty-acid and glyceride compositions of the oils of four plants of the family Malvaceae have been studied. They all belong to the palmito-oleo-linoleic group.2. Their glyceride structure does not correspond to the principle of statistical distribution, since almost all the unsaturated-acid radicals are concentrated in the position.Order of the Red Banner of Labor Institute of the Chemistry of Plant Substances of the Academy of Sciences of the Uzbek SSR.

PMR spectra of the dioxane lignins of some plants of the family Malvaceae

Analysis of PMR spectra of the dioxane lignins of three species ofAthea, of kenaf, and of the cotton plant has shown that the number of free aromatic protons does not correlate with the number of OCH₃ groups, which indicates different degrees of condensation of the dioxane lignins studied. In all the preparations a very small amount of coumarane structures were found. The aliphatic OH groups have been distinguished as primary (γ-OH) and secondary (α-OH) and their quantitative estimation has been carried out from the PMR spectra.

GC-MS Analysis of the essential oils of some plants of the Asteraceae Dumort family

An investigation has been made of the chemical composition of essential oils (EOs) of plants of the familyAsteraceae Dumort: Achillea filipendulinaLam., Artemisia persicaBoiss., Artemisia leucodesSchrenk, and Artemisia lehmannianaBunge.It has been shown that the composition of the EOs. of plants of one and the same species depends on the conditions and growth sites.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan [IKhRV AN RUz].
