One new flavonoid glycoside (1) and one new triterpenoid cinnamate (2) were isolated from Nervilia fordii. The structures of 1 and 2 were determined by extensive NMR and HRESIMS to be 7-O-β-d-glucopyranosylapigenin-8-C-β-d-glucopyranosyl-(1 → 2)-β-d-glucopyranoside and 24(S/β)-dihydrocycloeucalenol-3-(Z)-p-hydroxycinnamate, respectively.

From the water-soluble extract of the aerial part of herbal plant Nervilia fordii, three new cycloartane glycosides, named as nervisides A (1), B (2), and C (3), were isolated. Their structures were elucidated through a combination of spectroscopic analysis and hydrolysis. At the same time, the new compounds were tested for their cytotoxicities in vitro against human tumor cell lines (CNE, Hep-2, and HepG2) using MTT method.

Polarized structured nitrides semiconductors become attractive for they possess unique electronic properties with environment friendly. The stability, ferroelectricity, photocatalytic and photovoltaic properties of super-wurtzite Mg2XN3 (X= Bi, Mo, Nb, Sb,...

Five new cycloartane glycosides, nervisides D–H (1–5), were isolated from the AcOEt‐ and H2O‐soluble portions of the 90% EtOH extract of the aerial part of the plant Nervilia fordii. The structures of the isolated glycosides were elucidated by extensive spectroscopic analysis including HR‐ESI‐MS and NMR data. The isolated nervisides D–H were evaluated for the cytotoxic activity in vitro against human‐tumor cell lines (CNE, Hep‐2 and HepG2) with the MTT method.
