From the aerial parts of Lonicera japonica THUNB.(Caprifoliaceae), twelve triterpenoidalsaponins having oleanolic acid and hederagenin as aglycones, were isolated.The stnuctures of fournew saponins, 6, 9, 11 and 12, were established to be 3-O-α-L-arabinopyranosyl-28-O-[β-Dglucopyramosyl (1→6)-β-D-glucopyranosyl] oleanolic acid, 3-O-[α-L-rahmnopyranosyl (1→2)-α-L-arabinopyranosyl]-28-O-β-D-glucopyramosyl hederagenin, 3-O-[α-L-rhamnopyramosyl (1→2)-α-L-arabinopyramosyl]-28-O-[β-D-glucopyramosyl… Expand
Two New Triterpenoid Saponins from Akebia quinata (Thunb.) Decne.
Two new triterpenoid saponins, hederagenin 3-O-α-L-arabinopyranosyl-(1→2)-α-L-arabinopyranoside named akeboside La (compound 1), oleanolic acid 3-O-α-L-arabinopyranosyl-(1→2)-β-D-glucopyranosideExpand
Triterpenoidal saponins of Pulsatilla koreana roots.
Sixteen (1-16) triterpenoidal saponins were isolated from the roots of Pulsatilla koreana, of which four were determined as the previously unknownExpand
Hederagenin glycosides from the fruits of Blighia unijugata.
TLDR
A phytochemical investigation of Blighia unijugata led to the isolation of eleven hederagenin glycosides, six of which are previously undescribed and two are described in their native forms for the first time. Expand
Four new triterpene glycosides from Nigella damascena.
TLDR
Four new triterpene glycosides were derived from the air-dried aerial parts of Nigella damascena L. (Ranunculaceae), and the structures were elucidated on the basis of spectroscopic data including 2D NMR spectra and chemical evidence. Expand
Immunomodulatory, hemolytic properties and cytotoxic activity potent of triterpenoid saponins from Cephalaria balansae.
TLDR
Four previously undescribed triterpenoid saponins based on hederagenin type aglycone, namely, balansoides A-D, along with ten known compounds were evaluated for their potential cytotoxic activity against HEK-293, A-549, HeLa cells and for hemolytic properties on human blood cells. Expand
Triterpene Saponins from the Leaves of Ilex pernyi
AIM: To study the chemical constituents from the leaves of Ilex pernyi. METHODS: The chemical constituents were isolated by various column chromatographic methods and their structures were identifiedExpand
Constituents of the root of Anemone tomentosa
TLDR
A new diterpene glycoside, tomentoside I, along with eleven known compounds, including the four coumarins, 4,5-dimethoxyl-7-methylcoumarin, are isolated from the ethanolic extract of the root of Anemone tomentosa and their chemical structures were elucidated by spectroscopic methods. Expand
Saponins and Volatile Constituents from Lonicera japonica Growing in the Western Himalayan Region of India †
TLDR
Structures established on the basis of IR, 1D- and 2D-NMR (HMQC and HMBC) spectroscopic and ESI-QTOF-MS/MS analysis indicated the presence of two long chain hydrocarbons, heneicosane and octadecane, as major constituents of L. japonica. Expand
Lignans from Lonicerae caulis.
A new 2,7`-cyclolignan named lonicerinol (1) along with eight known lignans, (-)-epipinoresinol (2), (-)-pinoresinol (3), 9α-hydroxypinoresinol (4), 7R,8S-dihydrodehydrodiconiferyl alcohol (5),Expand
Identification of Phytochemicals From the Caulis of Lonicera japonica
Lonicera japonica Thunb. (Caprifoliaceae) is widely distributed in various areas including Korea, China, Japan, and other East Asian countries [1], and the caulis of L. japonica is a traditionalExpand
