29-Norlupane-1β-hydroxy-3,20-dione, a new norlupane triterpenoid from the twigs and leaves of Phyllanthus acidus. Nat Prod Res. 2019 Dec 09;:1-6 Authors: Sichaem J, Vo HC, Nha-Tran T, Jarupinthusophon S, Niamnont N, Srikittiwanna K, Nguyen TK, Tran TN, Le TT, Duong TH Abstract A new norlupane triterpenoid, 29-norlupane-1β-hydroxy-3,20-dione (1), along with ten known compounds, 29-norlup-1-ene-3,20-dione (2), phyllanthol (3), phyllanthone (4), glochidone (5), lupeol (6), lupeone (7), 4-hydroxybenzoic acid (8), 4-hydroxybenzaldehyde (9), phyllane A (10) and methyl β-orsellinate (11) were isolated the twigs and leaves of Phyllanthus acidus. The structure of 1 was identified by interpretation of their spectroscopic data and comparison with those reported in the literature. In addition, all isolated compounds 1-11 were evaluated for their antioxidant activity. PMID: 31815547 [PubMed - as supplied by publisher]
