Oil Peony and Peony seed Oil can Oil and Medicinal Peony be planted in Fu'an City in the south?

Oil peony is a general term for peony varieties with a grain oil yield of ≥ 20% in production. Zhao Xiaoqing found in 2009 that the seed oil extracted from the seeds of 'Fengdan' peony is not only edible, but also has a high content of unsaturated fatty acids, which has the potential and value to be developed into edible oil. Zhu Wenyi confirmed that peony seed oil has no genetic toxicity, acute or subacute toxicity and is safe as edible oil in 2010. With the approval of the Ministry of Health in March 2011, peony seed oil has officially become a new resource food oil. The high quality of peony seed oil is shown in the high content of unsaturated fatty acids 83.05%-90%, of which linoleic acid content is 19.09%-34.90%, especially linolenic acid content is 31.56%-66.85%. Linolenic acid is known as "plant brain gold", which can enhance intelligence and lower blood.

The functions of pressing blood lipids and dredging cardio-cerebral vessels are indispensable to the human body, but they cannot be synthesized by themselves. The linolenic acid content of peony seed oil is higher than that of rapeseed oil (8.4%), soybean oil (6.7%), sunflower oil (4.5%), olive oil (0.73%) and peanut oil (0.08%). Thirteen compounds such as ivy swab, oleanolic acid, stigmasterol, apigenin, luteolin and kaempferol in seed oil were identified. Gao Tingting identified 11 compounds such as 9-heptadecanol, 8-hexadecanol, trimethyl cyclohexyl ester, squalene and lauryl peroxide by meteorological chromatography-mass spectrometry. Peony seed oil also contains vitamins, amino acids, polysaccharides and trace elements, as well as flavonoids, stilbenes and other pharmacological active substances, which can resist diabetes and promote insulin secretion. The extraction methods of peony seed oil are directly related to the quality and oil yield of peony seed oil. at present, there are five commonly used methods: press extraction, supercritical CO2 extraction, Soxhlet extraction, microwave-assisted extraction and ultrasonic-assisted extraction. In contrast, the oil yield of supercritical CO2 extraction was the highest, which was more than 27%, and the time of microwave-assisted extraction was the shortest, only 8 minutes. The oil obtained by supercritical CO2 extraction, microwave-assisted extraction and ultrasonic-assisted extraction was bright yellow, clear and transparent, and had good stability, and there was no significant change after 3 months. Therefore, supercritical CO2 extraction is the first choice for the preparation of peony seed oil.

The reason why the cultivation value and prospect of oil peony has been widely concerned lies not only in the nutritional value and quality of seed oil, but also in planting and economic benefits. Because of its strong growth adaptability, oil peony can be planted under the conditions of barren land, drought and lack of water, especially in the environment where barren slopes, barren hills and woodlands are not suitable for planting cash crops, saving farmland and remarkable ecological benefits. it greatly reduces the cost of planting management and has the economic advantage of popularization. Oil peony can adapt to most of the climate and environment in China, has strong resistance, cold and drought tolerance, a wide range of suitable cultivation areas, and has the regional advantage of popularization. At the same time, oil peony has high grain yield and economic output value, which is good in Shandong, Henan, Anhui, Shaanxi, Hubei and other main cultivation areas. Under good water and fertilizer conditions, the yield per mu can reach 283.63kg, the average pod weight per mu is 51.2 g, and the seed-fruit ratio is about 41.3%. After continuous breeding and research, the new variety 'Xiangfeng', which is introduced by the Engineering and Technology Research Center of Oil Peony, has a yield of 203 kg per mu in 6 years and a yield per mu in 8 years can reach 310kg (Yu Ling et al. 2017). According to the income calculation of the current market price of 18 yuan / kg, the economic income of planting is considerable. At the same time, the oil yield of peony seeds is ≥ 22%, and the follow-up industrial economic chain is long and the added value is high, so it has the value and prospect of development and utilization for health products and cosmetics.
