Gypsogenic acid from the roots ofAcanthophyllum subglabrum andA. gypsophiloides

Triterpenoid saponins of the Caryophyllaceae and Illecebraceae family

“…In any case, it is possible to speak of repetitive occurrences of the three sapogenins, listed in the table within the Caryophyllaceae family, especially when considering x (2) x(?) x(2) Putieva et al (1970), Belous and Ryabinin (1967), Kondratenko et al (1981) …”

Dianthosaponins A-F, Triterpene Saponins, Flavonoid Glycoside, Aromatic Amide Glucoside and .GAMMA.-Pyrone Glucoside from Dianthus japonicus

“…These functionalities were the same as those of the aglycone of co-occurring dianversicoside G (10), and the 13 C-NMR chemical shifts were superimposable on those of 10 (Table 3). Thus, dianthosaponin A (1) was expected to be a gypsogenic acid 12,13) bisdesmoside, and the 1 H-1 H correlation spectroscopy (COSY) and heteronuclear single quantum correlation (HSQC) spectra were used for extensive assignment of the signals. The terminal arabinopyranoside was placed on the hydroxy group at the 3-position, since significant correlation peak was observed between H-1Ј (d H 4.93) and C-3 (d C 85.1) in the heteronuclear multiple bond connectivity (HMBC) spectrum ( (Table 2).…”

“…Dianthosaponin F (6), [a] D ϩ15.5, was isolated as an amorphous powder and its elemental composition was determined to be C 35 H 50 O 12 . IR spectrum exhibited a strong absorption band at 1770 cm…”
