Fifty-four different extracts of nine Bolivian plants belonging to the family Asteraceae were evaluated for their
radical scavenging activity by the DPPH
, NBT/hypoxanthine superoxide, and
OH/luminol chemiluminescence
methods, and for their antioxidant activity by the h-carotene bleaching test. The total phenolic content was also
determined by the Folin-Ciocalteu method, and the oxidative stability by the Rancimat test. Both remarkably high
phenolic content and radical scavenging and antioxidant activities were found mainly in the ethyl acetate fractions
among the different plant extracts. Some ethyl acetate and even some defatted crude extracts exhibited activities
comparable to those of commercial extracts/compounds, thus making it possible to consider some of the studied
plants as a potential source of antioxidants of natural origin.

So far, some aromatic aldehydes have been put to use as
food additives in food processing (Chen, Song, Wang, &
Huang, 2003; Huang, Liu, & Chen, 2003). They can be
used as spices and food preservatives. In our previous papers,
cuminaldehyde (Chen et al., 2003) and salinaldehyde
(Huang et al., 2003) were found to have inhibition effects
on mushroom tyrosinase. Recently, there is an increasing
demand by consumers for natural substances as food ingredients.
Natural compounds will be widely accepted by consumers
in the market (Jang, Sanada, Ushio, Tanaka, &
Ohshima, 2002). In our continuous research, 4-isopropylsalicylaldehyde,
isolated as an active tyrosinase inhibitor
from African medicinal plants (Nihei, Yamagiwa, Kamikawa,
& Kubo, 2004), was found to have much stronger
inhibitory effect on tyrosinase. The aim of the present work
was, therefore, to carry out a kinetic study of the inhibition
of 4-isopropylsalicylaldehyde on mushroom tyrosinase and
to evaluate the kinetic parameters and constants characterizing
the system as a model. Furthermore, comparisons of
the inhibition of 4-isopropylsalicylaldehyde,

我只知道1楼的内容绝对不是和FM有关的
貌似是某生物学论文

虽说有不少人玩E文版本的fm
不过LZ的这个帖子也太水了，水的太搞笑了......呵呵......

还是7楼的牛比......
是有机自由基方面的论文..哈哈~~~赞一个...哈哈
最近在搞这个....郁闷
