Four new bis-iridoid glycosides, saungmaygaosides A-D (1-4), and six known iridoid glycosides (5-10) were isolated from the n-butanol extract of the stems of Picrorhiza kurroa collected in Myanmar. Their structures were elucidated by extensive spectroscopic techniques. All of the isolates were assayed for anti-Vpr activity, using TREx-HeLa-Vpr cells. Among the isolates, saungmaygaoside D (4), sylvestroside IV dimethyl acetal (7), and sweroside (8) were the most potent inhibitors with effective doses of 5 and 10 μM, respectively, without showing any notable cytotoxicities.

Objective: To investigate the therapeutic effects of Cornus officinalis iridoid glycosides (CIG) on rats with chronic renal failure (CRF).
Methods: CRF was induced in adult male Sprague Dawley rats by nephrectomy. The rats were randomly divided into six groups: sham, sham+high-dose CIG (120 mg/kg/d for 14 days), CRF, CRF+low-dose CIG (60 mg/kg/d for 14 days), CRF+high-dose CIG, and CRF+high-dose CIG+ML385 (an inhibitor of nuclear factor erythroid 2-related factor 2 (Nrf2), single administration at 30 mg/kg).

Postmenopausal osteoporosis (PMOP) is a chronic systemic bone metabolism disorder. Promotion in the patterns of human bone marrow mesenchymal stem cells (hBMSCs) differentiation towards osteoblasts contributes to alleviating osteoporosis. Aucubin, a natural compound isolated from the well-known herbal medicine Eucommia, was previously shown to possess various pharmacological effects.

Separation of polar compounds especially with similar polarities is challenging. In the present study, three polar compounds with similar polarities, including gentiopicroside, sweroside and mangiferin, have been successfully separated from Swertia mussotii by a combination of two counter-current chromatography modes. With the selected solvent system of ethyl acetate/n-butanol/water (8/2/10, v/v), a continuous injection mode was firstly employed.
