Three new isobenzofurans from Lavandula angustifolia and their bioactivities

Three new isobenzofurans, lavandulactones A–C (1–3), together with three known ones (4–6), were isolated from the whole herb of Lavandula angustifolia. Their structures were established on the basis of detailed spectroscopic analysis (1D- and 2D-NMR, HRESIMS, UV, and IR) and comparison with data reported in the literature. New isolates were evaluated for their anti-tobacco mosaic virus (TMV) activities and cytotoxicity activities. The results revealed that compounds 1–3 showed high anti-TMV activity with inhibition rate of 31.8, 29.6 and 33.4%, respectively. These rates are higher than that of positive control. Compounds 1–3 also showed weak inhibitory activities against some tested human tumor cell lines with IC₅₀ values ranging from 1.5 to 5.7 μM.     

Three new arylbenzofurans from Lavandula angustifolia and their bioactivities

Three new arylbenzofurans, 2-(7-methoxy-2-(4-methoxyphenyl)-3-methylbenzofuran-5-yl)ethanol (1), 4-(5-(2-hydroxyethyl)-7-methoxy-3-methylbenzofuran-2-yl)phenol (2), and 2-(6-methoxy-2-(4- methoxyphenyl)-3-methylbenzofuran-5-yl)ethanol (3), together with three known ones (4–6) were isolated from the whole plant of Lavandula angustifolia. Their structures were determined by means of HRESIMS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1–3 and 5 were tested for their anti-tobacoo mosaic virus (TMV) activities, and Compounds 1–6 were tested for their cytotoxicity activities. In our assay, Compounds 1–3 showed high anti-TMV activity with inhibition rate of 38.2, 35.2, and 34.0%, which superior to positive control Ningnanmycin. Compounds 1–6 also showed weak inhibitory activities against some tested human tumor cell lines with IC50 values in the range of 2.2–8.2 μM.     

温度对薰衣草花精气成分的影响

用恒温水浴锅控制温度,通过大气采样器和活性炭吸附管捕集薰衣草花精气,并用气质联用法(GC-MS)对其进行分析鉴定,研究温度对薰衣草花精气的影响。结果显示:不同温度条件下薰衣草花精气的成分组成不尽相同。只有11种成分在所有温度梯度中均可检测到,而有6种成分在一些温度中未能同时检测到;不同温度条件下薰衣草花精气各组分的含量也不尽相同。其中,异丙基对甲苯在所有温度梯度中的相对含量均为最高,其次为柠檬烯。而5、25、35、40℃时,1-甲基乙烯基对甲苯的相对含量位居第3。15℃时,莰烯位居第3。45、50℃时,β-月桂烯位居第3;在11种共有成分中,除薰衣草醇和乙酸薰衣草酯2种成分挥发量的最高值出现在40,45℃时急剧下降,而50℃时又急剧上升外,β-月桂烯、异丙基对甲苯、柠檬烯等9种成分挥发量的最高值出现在45℃,随后急剧下降,这表明薰衣草花精气成分温度间差异显著。为定量分析他们之间的关系,以温度为自变量,标准化处理后的11种挥发物峰面积分别为因变量,采用回归分析法建立了11个非线性回归方程。
