Triterpene Glycosides from Kalopanax septemlobum. IV. Glycoside Composition of Fruit from Plants Introduced into Crimea

“…Separation of total glycosides from pericarp eluted successively glycosides 1 (10 mg), 2 (80 mg), 3 (7 mg), 4 (90 mg), 5 (70 mg), and 6 (65 mg); of total glycosides from seeds, 2 (10 mg), 7 (20 mg), 8, (5 mg), 9 (60 mg), 5 (20 mg), 10 (7 mg), and 6 (3 mg). Glycosides 1-8 and 10 were identified by TLC in various solvent systems as known glycosides that we isolated previously from leaves and fruit of Hedera taurica [3] and from leaves of K. septemlobum [2], by acid and alkaline hydrolysis, and by comparing their NMR spectra with those in the literature [2,3]. Glycoside 9 was not identified as any known glycoside.…”

“…Glycosides were isolated from individually selected seeds and pericarp by the usual method [2] that includes thorough grinding, defatting, and extraction of total glycosides by isopropanol (80%). Raw total glycosides were obtained from pericarp (1.8 g) and seeds (0.1 g).…”

Self-association and complexation of triterpene glycosides and cholesterol

“…Glycosides 1 and 2 were found in plants of various species of Hedera and Kalopanax, in Aralia elata and Acanthopanax sieboldianus [4][5][6]; 1 was also found in Polyscias dichroostachya [4]; 2, Schefflera octophylla [7]. Glycosides 1 and 2 are included in the well-known drugs for treating coughs Gedeliks® and Prospan®, which are formulated from Hedera helix leaves [8].…”

Triterpene glycosides from Kalopanax septemlobum. VII. Minor glycosides from stems of Kalopanax septemlobum var. maximowiczii and Kalopanax septemlobum var. typicum

“…Fraction C in variety typicum contained two glycosides with similar chromatographic mobilities, minor C 1 (2) and predominant C 2 (3). This fraction contained only 3 in variety maximowiczii [1].…”

“…Glycosides 2, 12, and 14-16 were identified using TLC and authentic samples isolated and described previously from Hedera taurica [2] and K. septemlobum [3]. Their structures were also confirmed by comparing their 13 C NMR spectra with those in the literature [2][3][4].…”
