From the methanol extract of the aerial parts of Peperomia blanda (Piperaceae), two chromenes were isolated and characterized mainly through application of 2D-NMR spectroscopy. The structures were 2S-(4-methyl-3-pentenyl)-6-formyl-8-hydroxy-2,7-dimethyl-2H-chromene and 2S-(4-methyl-3-pentenyl)-5-hydroxy-6-formyl-2,7-dimethyl-2H-chromene named as blandachromenes I and II, respectively.
从豆瓣绿（胡椒科）地上部分的甲醇提取物中分离得到两种色烯，并主要通过二维核磁共振光谱对其进行了表征。其结构分别为2S-(4-甲基-3-戊烯基)-6-甲酰基-8-羟基-2,7-二甲基-2H-色烯和2S-(4-甲基-3-戊烯基)-5-羟基-6-甲酰基-2,7-二甲基-2H-色烯，分别命名为豆瓣绿色烯I和豆瓣绿色烯II。
