Olive oil is a kind of high-quality edible oil obtained by quick extraction from the fresh olive fruit. It has rich biological activity and positive effect on human health which leads to the increase of the demand for olive oil. Olive pomace is a by-product of olive oil during processing which is also rich in biologically active ingredients. But it is often treated as waste, not only causes environmental pollution but also a great waste of resources. In order to explore the high value utilization of olive oil by-products, the extract components of olive oil pomace by benzene, ethanol and acetone were analyzed by gas chromatography-mass spectrometry. The results showed that there were 109, 70, and 71 components which identified in benzene, ethanol and acetone extracts of olive oil pomade respectively. Many of these components can be resourced in industries of biomedicine, bioenergy, spices, and food additives.

The fruit of Ginkgo biloba is widely concerned because of its high economic and medical value. In this study, efficient extraction methods were used to identify the bioactive components in the fruit of Ginkgo biloba. The bioactive constituents of Ginkgo biloba fruit were identified and the uses of these bioactive components were discussed. There are more than 160 kinds of chemical extracts in Ginkgo biloba fruit. It mainly contains flavonoids, terpenes, phenols, alkaloids, polyisopentene, quinine acid, linoleic acid, monoxalic acid, gingol, gingosterone and other substances. It contains a variety of substances, and has many applications in anti-bacterial, anti-tumor, lipid-lowering and other aspects. The results suggested that Ginkgo biloba fruit has great potential in chemical raw materials, biological health care, biomedical treatment, aroma and bioenergy.
