Rresults from those studies can be summariazed as follow:(1) A preliminary study no correlationship between the UV-VIS reflection spectrum of tomato fruit surface and the lycopene amount of tomato fruit was undertaken. Based on observation from this study, a damage-free and in-situ detection technique of lycopene amount from tomato was developed with UV-VIS reflection spectroscopy;(2) The geometrical isomers of lycopene were separated successfully on C30-HPLC-PDA-ELSD. The absorption coefficients of Z-isomers were consequently dedermined. The geometrical isomer composition of lycopene could therefore be assessed. Those efforts formed a solid base to identify the natural product from synthetic compound of lycopene;(3) Lycopene resource from the fruit of Autumn oliver was proved to be available for industrial application. An extraction methos of lycopene from the fruit of Autumn oliver by supercritical carbon dioxide was developed at laboratory scale;(4) A method to extract lycopene by supercritical liquid with improved efficiency was developed; Data from this investigation suggested that a proper raw material pre-extraction process was important for a better extraction efficiency;(5) Variation in the geometrical isomer composition of lycopene during its metabolish in rat was assessed. A large amount of Z-isomers were observed. This variation took place in serum;(6) The absorption rate and accumulation in serum of natural lycopene in rat were assessed;(7) Ability to quench singlet oxygen by different geometrical isomers of lycopene was compared;(8) It was detected that whether natural lycopene had functions to regule blood-lipids and LDL antioxidation;(9) A C31 degradation piece of lycopene was found in the prostate gland of rat.

That, though it was my mother's fate to die young, she spent the last years of her life with me; that, whenever I wished to help any man in his need, or on any other occasion, I was never told that I had not the means of doing it; and that to myself the same necessity never happened, to receive anything from another; that I have such a wife, so obedient, and so affectionate, and so simple; that I had abundance of good masters for my children; and that remedies have been shown to me by dreams, both others, and against bloodspitting and giddiness...; and that, when I had an inclination to philosophy, I did not fall into the hands of any sophist, and that I did not waste my time on writers of histories, or in the resolution of syllogisms, or occupy myself about the investigation of appearances in the heavens; for all these things require the help of the gods and fortune.

清晰的印象经常出现在我心中，告诉我顺生自然，告诉我那是一种什么样的人生，因此，只要依靠诸神及其赐福，其保佑，其启示，就没有什么能阻止我顺生自然，尽管由于我自身的不足和没有注意诸神的警告（或者差不多可以说是诸神的直接指令），我还不能完全做到；我的身体已经维持了很长一段时间这种生活；我永远不会接触本尼迪克特或狄奥多士，我曾经陷入恋爱的激情，但现在已经摆脱；当我和汝斯堤古在一起时常常发脾气，但我从来没有做过一件让人后悔的事
