TL;DR: From the leaves of Neolitsea dealbata R.Br. were isolated taraxerol and sitosterol together with a new triterpene,?cycloneolitsin?, C33H56O.
Abstract: From the leaves of Neolitsea dealbata R.Br. Merr. were isolated taraxerol and sitosterol together with a new triterpene, ?cycloneolitsin?, C33H56O. By converting both it and cycloartenol into a common derivative, the structure was established as 3β-methoxy-24,24- dimethyl-9,19-cyclolanost-25-ene (Ib).

Abstract: From the rhizoma of Peltoboykinia tellimoides (MAXIM.) HARA, two triterpene acids were isolated. One of them, a new triterpene, named β-peltoboykinolic acid (I), mp 220-222°(decomp.), [α]24D+114°, has been established to be olean-12-ene-3β-ol-27-oic acid and another, named α-peltoboykinolic acid (II), mp 234-236°, [α]17D+121°, to be urs-12-ene-3β-ol-27-oic acid, which is identical with a compound derived from quinovic acid by L. Ruzicka, et al. in 1946. These are the first examples of naturally occurring triterpene acids with the only carboxyl group at C-27 of ursane and oleanane types.

TL;DR: In this article, the retention times and structures of polycyclic triterpenes are discussed and an attempt has been made to arrange the compounds in groups of closely related structures.
Abstract: Publisher Summary This chapter aims to draw together some data and observations on methodology that should be a useful guide in evaluating the usefulness of gas-liquid chromatography (GLC) for biochemical studies involving the polycyclic triterpenes. The chapter discusses the retention times and the structures of polycyclic triterpenes. The relative retention times of a number of polycyclie triterpenes are summarized and an attempt has been made to arrange the compounds in groups of closely related structures. As an example of the application of gas chromatography in the identification and isolation of a polycyclic triterpene in biological fluid, detection of the triterpene lupeol in silkworm blood is described.

Abstract: The: triterpene glycoside gypsoside was first isolated from Gypsophila pacifica [1] and then from other species of plants of the family Caryophyllaceae [2-4, 6, 7]. We have studied the triterpene glycosides of Gypsophila bicolor (Freyn etSint.)Litv, gathered in the botanical garden of AS TurkmSSR. The seeds, previously treated with chloroform, together with the bracts, were first extracted with 96% and then with 50% aqueous ethanol with heating. By chromatography in a thin layer of silica gel in systems 1) [bu tanl -o l -ace t ic acid-water (4: 1:5)] and 2) [butan-1-ol-ethanol-25% ammonia (7 : 2 : 5)] 'the extract was shown to contain two triterpene glycosides. The extract was passed through a small layer of cellulose powder and washed with system 1. When the combined eluates were concentrated, a single glycoside preci pitated which, after several reprecipitations from water-saturated butanol, had mp 218-222 ° C (decomp.), [c~]~ +21 ± 2\" (c 1; aqueous ethanol); acetate, mp 150-154 ° C, [c~]~ +11 i 2 ° (c 1.1; chloroform). The yield of pure glycosides was 2.5% of the weight of the Mr-dry seeds.
