In Ayurvedic medicine, Salacia reticulata is known to be useful against various metabolic diseases, including diabetes and obesity. In this study, we attempted to clarify the antiobesity mechanism and the safety of S. reticulata in vivo and in vitro. We gave ordinary MF feed, alone or mixed with S. reticulata (0.3 or 1.0%), to Tsumura Suzuki obesity diabetes (TSOD) mice (spontaneous obese type II ...... hiện toàn bộ
Two new ɑ-pyrone derivatives from the endophytic Diaporthe sp. ECN371
Journal of Natural Medicines - Tập 76 - Trang 462-467 - 2022
Ken-ichi Nakashima, Yuka Higuchi, Junko Tomida, Yoshiaki Kawamura, Makoto Inoue
Diaportholides A (1) and B (2), two polyketides with ɑ-pyrone moieties, were isolated from the cultures of an endophytic Diaporthe sp. ECN371 isolated from Orixa japonica, together with four known polyketides, phomopsolide B (3), phomopsolidones A (4) and B (5), and 5-[(1R)-1-hydroxyethyl]-γ-oxo-2-furanbutanoic acid (6). The structures of 1 and 2 were determined by extensive analysis of NMR and MS...... hiện toàn bộ

Shinzo Hosoi, Eri Shimizu, Toshihiro Tanaka, Eiji Sakai, Mitsuko Yamada, Akiyo Sakushima
Six phenolic compounds were isolated from the flowers of Trachelospermum asiaticum var. intermedium (Apocynaceae). These structures were determined on the basis of spectral data.
Two new alkaloids from Crinum asiaticum var. japonicum
Journal of Natural Medicines - Tập 73 - Trang 648-652 - 2019
Yuta Endo, Yu Sugiura, Mariko Funasaki, Hiroyuki Kagechika, Masami Ishibashi, Ayumi Ohsaki
A new crinine-type alkaloid crijaponine A (1), a new galanthamine-type alkaloid crijaponine B (2), and 11 known alkaloids—ungeremine (3), lycorine (4), 2-O-acetyllycorine (5), 1, 2-O-diacetyllycorine (6), (−)-crinine (7), 11-hydroxyvittatine (8), hamayne (9), (+)-epibuphanisine (10), crinamine (11), yemenine A (12), and epinorgalanthamine (13)—were isolated from the rhizome and fruits of Crinum as...... hiện toàn bộ

Two new isoflavone glycosides, tectorigenin 7-O-β-d-glucopyranoside-4′-O-[β-d-glucopyranosyl-(1″″ → 6′′′)-β-d-glucopyranoside] (1) and iristectorigenin B 4′-O-[β-d-glucopyranosyl-(1′′′ → 6″)-β-d-glucopyranoside] (2), together with 11 known compounds, including six isoflavones, tectorigenin 7-O-β-d-glucopyranoside-4′-O-β-d-glucopyranoside (3), tectorigenin 4′-O-[β-d-glucopyranosyl-(1′′′ → 6″)-β-d-g...... hiện toàn bộ
Three new xanthones from the leaves of Garcinia lancilimba
Journal of Natural Medicines - Tập 70 - Trang 173-178 - 2015
Yating Sun, Dahong Li, Cuicui Jia, Chunmei Xue, Jiao Bai, Zhanlin Li, Huiming Hua
Three new prenylated xanthones, garcinexanthones G−I (1–3), together with fifteen known ones (4–18) were identified from the leaves of Garcinia lancilimba. Their structures were determined by extensive spectroscopic analyses. Most of the compounds exhibited inhibitory effects against HL-60 (human leukemia), A549 (human lung cancer), and MCF-7 (human breast cancer) cell lines. Among them, compounds...... hiện toàn bộ
Euchronin A–F isolated from the Arnebia euchroma (Royle) Johnst. and their anti-proliferative activities in vitro
Journal of Natural Medicines - Tập 78 - Trang 33-41 - 2023
Zhen-Peng Zhang, Yan Liu, Hai-Dan Zou, Juan Pan, Zhi-Chao Hao, Wei Guan, Adnan Mohammed Algradi, Hai-Xue Kuang, Bing-You Yang
Six new naphthoquinones, euchronin A–F (1–6) and nine known naphthoquinones (7–15), were isolated from the roots of Arnebia euchroma (Royle) Johnst. The structures of the new compounds were confirmed by extensive spectroscopic analyses, including UV, IR, HR-ESI–MS, 1D and 2D NMR. In the present study, we estimated the anti-proliferative activities of these compounds with HaCaT cells. The results i...... hiện toàn bộ
New 8,12;8,20-diepoxy-8,14-secopregnane hexa- and hepta-glycosides from the roots of Asclepias tuberosa
Journal of Natural Medicines - Tập 72 - Trang 347-356 - 2017
Tsutomu Warashina, Toshio Miyase
Previously, phytochemical investigation of the roots of Asclepias tuberosa (Asclepiadaceae) led to the isolation of some 8,12;8,20-diepoxy-8,14-secopregnane tri-, tetra-, and penta-glycosides. An additional eight new minor 8,12;8,20-diepoxy-8,14-secopregnane glycosides were afforded in the recent investigation of this plant. These glycosides consisted of six or seven 2,6-dideoxy-hexopyranoses toge...... hiện toàn bộ

Febrifugine and isofebrifugine alkaloid mixtures extracted from the leaves and buds of Hydrangea macrophylla var. Otaksa, collected during different months, in Japan, were quantified using high-performance liquid chromatography. Leaves collected during the flowering season, namely from June to August, contained 0.16–0.31 mg/g of the alkaloid mixture, whereas those collected from September to Decem...... hiện toàn bộ
