Sesquiterpene lactones and other constituents from Stevia jorullensis

Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Ana Lidia Pérez-Castorena, Antonio Nieto-Camacho, Emma MaldonadoAbstractA chemical study of the aerial parts of Stevia jorullensis was carried out as a contribution to the knowledge of the chemistry of the genus Stevia. In this investigation the sesquiterpene lactones 11β,13-dihydrocostunolide (1), 11,13-dihydroreynosin (4), and 1β-hydroxycolartin (5) were isolated for the first time in the genus. Additionally, chlorogenic acid (8), the steroidal compounds β-sitosterol (2), stigmasterol (3), β-sitosteryl glucopyranoside (6), and stigmasteryl glucopyranoside (7) were also isolated. This is the third report of the presence of a 11,13-dihydrogermacranolide and the second of 11,13-dihydroeudesmanolides in the genus Stevia.

This study aims to assess whether older adults with low muscle mass or strength, in the presence of obesity, have an increased risk of knee (TKR) and hip replacement (THR) over 13  years. 1082 community-dwelling older adults (51% women; mean age 62.9 ± 7.5 years) were studied at baseline and multiple time points over 13 years. The incidence of TKR and THR was determined by data linkage to National Joint Replacement Registry. Appendicular lean and fat mass were measure d using DXA. Lower-limb muscle strength (LMS) was assessed by dynamometer. Low muscle mass and strength were defined as t...
