Abelmoschus manihot, named Abelmoschus manihot, belongs to Abelmoschus manihot family, and is a large annual herbaceous plant. Wild hibiscus is known as a panda plant and heart-saving herb in life because the wild hibiscus contains various bioactive substances, and the main components of the wild hibiscus comprise natural flavonoid compounds, unsaturated fatty acids (linoleic acid and linolenic acid) vitamin E, polyunsaturated fatty acids, high-polysaccharide gum, dietary fibers, trace elements such as selenium, zinc, calcium and various unsaponifiables. The natural flavonoid and the linoleic acid are nutrient substances which are necessary for human bodies, cannot be synthesized by self and have health care effect on human bodies and must be taken by diet. The wild hibiscus seeds are rich in total flavonoids, wherein the rare flavonoid monomer hyperin accounts for more than 50% of the total flavonoids.
At present, extraction methods of essential oil generally comprise a steam distillation method and an organic solvent extraction method, but the direct steam distillation method and the organic solvent extraction method have the problems of long extraction time, high energy consumption, low yield, environmental pollution and the like, and the extraction process adopts a toxic organic solvent, has high extraction temperature and causes oxidation damage to components, so that the obtained product has poor quality and low purity, and the problems of organic solvent residue harmful to human bodies and the like exist.
However, the direct use of the wild hibiscus seed oil basically has no flavonoid compounds, and the wild hibiscus seed oil, the stems and the leaves have less content of the sterone compounds, so that how to extract the essential oil with no pollution and complete component preservation from the wild hibiscus is very important.
