The invention also provides a method for identifying plant species of the labiate Isodon serra(Maxim.)Kudo and Rabdosia lophanthoides (Buch.-Ham. ex D. Don) Hara var. graciliflora (Benth.) Hara. The method comprises the step of comparing a rbcL gene or its sequence fragment of a plant sample, plant species of which is to be identified, to the gene pool provided by the invention. The invention also provides an application of the rbcL gene or its sequence fragment in identifying the labiate Rabdosia lophanthoides (Buch.-Ham. ex D. Don) Hara var. graciliflora (Benth.) Hara and the labiate Isodon serra(Maxim.)Kudo. It proves that the rbcL sequence is general, is easy to amplify and compare, and has good amplification and identification effects on the labiate Rabdosia lophanthoides (Buch.-Ham. ex D. Don) Hara var. graciliflora (Benth.) Hara and the labiate Isodon serra(Maxim.)Kudo.

The invention relates to water dispersible extract preparations derived from water soluble components of Labiatae family plant material, including plant material hay and previously extracted or spent hay, which possesses beneficial oral care properties, methods of their manufacturing and application of the preparations in oral care products.

An increase in specific antioxidant activity of extracts from rosemary (Rosemarinus officinalis) is obtained by the use of a blend of tetrafluoroethane and acetone in the extraction process. A blend of tetrafluoroethane, acetone and methanol improves total yield. A tetrafluoroethane and acetone blend has higher efficacy but comparatively lower yields. The methods yield a liquid and oily antioxidant extract that is readily mixed with a liquid product such as soybean oil for addition to animal feeds and human food. The methods simultaneously yield pharmaceutical grade essential oils in high yields.

Provided is a novel plant body comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae, wherein graft incompatibility is avoided or suppressed by using a graft medium between different-family plants.

The subject of the invention is antioxidant stabilisation and protection of nuts and/or seeds etc. and of products containing nuts and/or seeds. As known, nuts and seeds become rancid over time, and although several methods of preserving the same exist, including cooling, vacuum packaging, and the use of synthetic stabilizers, there is a need for improved methods of preserving nuts and seeds, as well as products comprising the same. According to this invention antioxidant extracts of plants from the Labiatae family, such as rosemary, sage, balm, oregano, summer savory, mint and thyme, which are natural antioxidants, are used for stabilisation nuts and/or seeds, as well as products comprising the same.

The invention discloses a sesterterpene compound 1-34 and a medicinal composition taking the compound as an active ingredient. A preparation method of the sesterterpene compound 1-34 comprises the following steps of: performing direct cold soaking or thermal reflux extraction on leaves or flowers or stems of labiatae tripterygium hypoglaucum plant with an organic solvent, i.e., petroleum ether or n-hexane or cyclohexane or chloroform or acetone or methanol or ethanol; or performing cold soaking or thermal reflux extraction on the organic solvent, and extracting with ethyl acetate to obtain a total extract; and repeatedly performing column chromatography on the total extract to obtain the compound.

The invention provides a foam separation method for concentrating and separating rosmarinic acid in labiatae (preferably perilla leaves). The method comprises the following steps: 1, a perilla leaf extract is prepared; 2, in the first-stage foam separation, a betaine type surfactant is used as an auxiliary agent, rosmarinic acid is effectively collected to a gas-liquid interface, concentration and separation of perilla rosmarinic acid are facilitated, and an obtained concentrated solution can be directly used as a raw material for producing perilla rosmarinic acid powder; and step 3, second-stage foam separation is carried out by taking the first-stage residual liquid as a feed liquid, so that the recovery effect of the rosmarinic acid in the perilla frutescens is further improved. According to the two-stage foam separation, the concentration (enrichment) ratio of the rosmarinic acid can be greatly increased (7.5-14.0), and the recovery rate can be increased (86%-99%). The method has the advantages of greenness in process, no addition of organic reagents, low energy consumption, simplicity in operation and the like, effectively solves the problem of concentration and separation of rosmarinic acid in perilla frutescens, and has good economic and social benefits.

Due to the lack of appropriate molecular markers, the recognition research of most of labiatae medicinal plants is almost blank. An EST-SSR primer developed from salvia miltiorrhiza bunge is utilized,salvia alba bunge, salvia officinalis, salvia officinalis Yunnan, salvia officinalis Xinjiang, salvia splendens, perilla frutescens, scutellaria baicalensis, mint, motherwort and platycodon grandiflorum are taken as materials, the universality of the salvia miltiorrhiza bunge EST-SSR primer among labiatae is detected, and clustering analysis is carried out. Universal detection results show that the radix salviae miltiorrhizae primers effectively amplify all test materials, and new EST-SSR markers and recognition references can be provided for research of labiatae medicinal plants.
