Ficus religiosa L., known as bodhi tree, is an ornamental tree and widely planted as an avenue and roadside tree due to ovate-rounded leaves with narrow, elongated tips. During 2018-2021, circular to oval-shaped leaf spots with pale white centers and brown-black edges surrounded by a chlorotic halo were observed on the leaves of more than 200 bodhi trees all year round in a park in Zhanjiang, Guangdong (N 21°15'22.

- The study aimed to identify hypoglycemic components from acid hydrolyzates of total saponins and assess their effectiveness in inhibiting α-glycosidase enzymes and PTP1B.
- Researchers purified eight compounds using silica gel chromatography and identified their structures through NMR, finding that one compound was previously unreported.
- Some isolated compounds showed strong inhibitory effects, particularly one with an IC value significantly lower than the control for α-glucosidase, suggesting potential use as a functional anti-diabetic agent.
Cytotoxic triterpenes from the acid hydrolyzate of Gynostemma pentaphyllum saponins.
J Asian Nat Prod Res
February 2018
One new dammarane-type triterpene, gypsapogenin A (1), was isolated from the acid hydrolyzate of total saponins from Gynostemma pentaphyllum (Thunb.) Makino, together with two known compounds, (20S,24S)-3β,20,21β,23β,25-pentahydroxy-21,24-cyclodammarane (2) and (23S)-3β-hydroxydammar-20,24-dien-21-oic acid 21,23-lactone (3). Its structural elucidations were accomplished mainly on the basis of the interpretation of spectroscopic data, such as IR, HR-TOF-MS, and NMR.

Methods: We searched the Cochrane Library, MEDLINE, EMBASE, Ovid, and Chinese Biological Medicine databases up to June 30, 2016. We also manually searched the articles from reference lists of the retrieved articles, which used the NPWT system in studies of vacuum-assisted closure therapy.
