Macranthoside B, a hederagenin saponin extracted from Lonicera macranthoides and its anti-tumor activities in vitro and in vivo.
The results showed that Macranthoside B exhibited strong anti-tumor effect and mitochondrion-mediated apoptosis induction involved in it.
Triticuside A, a Dietary Flavonoid, Inhibits Proliferation of Human Breast Cancer Cells Via Inducing Apoptosis
The results demonstrate for the first time the specific apoptogenic activity of Triticuside A in tumor cells and involvement of the mitochondrial apoptosis pathway and Akt/mTOR signaling pathway.
[Studies on the chemical constituents from stems and leaves of Lonicera macranthoides].
All the compounds are found for the first time from the stems and leaves of Lonicera macranthoides.
[Genetic variations in trnL-F sequence and phylogenetic clustering of Lycoris species].
The tree suggested that L. anhuiensis can not be taken as an independent species, while it may be of a variety or a hybrid of L. longituba.
A new triterpenoid saponin and other saponins from Salicornia europaea
A new triterpenoid saponin, 3β,29-dihydroxy-olean-12-en-28-oic acid 28-O-β-D-glucopyranosyl ester (1), together with four known triterpenoid saponins, i.e., oleanolic acid 28-O-β-D-glucoside (2),
Two Novel Ceramides with a Phytosphingolipid and a Tertiary Amide Structure from Zephyranthes candida
In the antimicrobial assay, candidamide A (1) and candidamide B (2) displayed moderate activities against bacteria Staphylococcus aureus and Escherichia coli, and fungi Aspergillus niger, Candida albicans and Trichophyton rubrum.
Two new nortriterpenoid saponins from Salicornia bigelovii Torr. and their cytotoxic activity.
Two new 30-nortriterpenoid glycosides are isolated for the first time from Chenopodiaceae and showed moderate activity against four cell lines, HL-60 (promyelocytic leukemia), MCF-7 (breast carcinoma), HepG2 (liver carcinoma) and A549 (lung carcinoma).
Inhibition of COX-2 and PGE2 in LPS-stimulated RAW264.7 cells by lonimacranthoide VI, a chlorogenic acid ester saponin.
Results indicate that lonimacranthoide VI is an important anti-inflammatory constituent of Lonicera macranthOides and that the anti- inflammatory effect is attributed to the inhibition of PGE2 production through COX activity and mRNA expression.
[Overview of current researches on Tibetan medicine "zuotai"].
The paper reviewed the resent progress of the study about "Zuotai" in chemical composition, pharmacodynamics and pharmacokinetics, toxicology and clinical application, and established the basis for further study.
[Studies on the chemical constituents of Salicornia europaea].
Compounds 1-4 are obtained from this genus for the first time and their structures were elucidated by spectroscopic methods.
