The invention discloses a terpene fragrance gene Hctps1 from hedychium coronarium and use thereof. The nucleotide sequence of the terpene fragrance gene from hedychium coronarium is shown by SEQ ID No.1; and the amino acid sequence of the protein coded by the gene is shown by SEQ ID No.2. The terpene fragrance gene Hctps1 from hedychium coronarium can be expressed in flower tissues of fragrant hedychium coronarium and expressed under induction by damage in laminae of hedychium coronarium, but cannot be expressed in non-fragrant hedychium coronarium varieties; and the expression of the gene isassociated with the growth process of flowers. The terpene fragrance gene Hctps1 from hedychium coronarium disclosed by the invention can be connected to any plant conversion vector and then transferred into cells of hedychium coronarium and other plants to produce transgenic fragrant or resistance varieties in which the gene is expressed, and thus, the gene can be used in production. In addition, specific molecular markers can be produced according to the sequence information of the gene and used to identify the fragrance gene types of hedychium coronarium and other plants or used in molecular marker-assisted selective breeding for improving selection rate in breeding.

The invention provides compound skin cream for treating chloasma and belongs to the technical field of externally used drugs of traditional Chinese medicine. A preparation method comprises the following steps: preparing radix notoginseng extract, flos carthami extract and flos magnoliae extract; preparing an oil phase and an aqueous phase; emulsifying the oil phase and the aqueous phase; adding the radix notoginseng extract, the flos carthami extract and the flos magnoliae extract to an emulsification product of the oil phase and the aqueous phase, reducing temperature to 55 DEG C and adding hedychium coronarium essence; reducing the temperature to 37 DEG C and performing discharging to obtain the cream. The compound skin cream has the following advantages: the cream is directly applied toan affected part and can relieve pain of a patient during treatment; by containing the radix notoginseng extract, the flos carthami extract and the flos magnoliae extract which have the effects of activating blood circulation, dispelling wind, resolving stagnation and caring skin, the compound preparation has a better treatment effect.

The present invention relates to a plant extract for treating diabetes and a process for making same. The plant extract of the invention is prepared from an overground part of Hedychium coronarium Koenig, which has the efficacies of lowering blood glucose, increasing insulin levels, reducing insulin resistance and treating and / or preventing diabetes without overly reducing blood glucose in a subject, i.e., not reducing blood glucose in a fasting subject. Also provided herein is a method for treating diabetes in a subject in need thereof comprising administering an effective amount of the plant extract to the subject.

The present invention is related to the use of an overground part of Hedychium coronarium Koenig in lowering blood glucose, increasing insulin levels and treating and / or preventing diabetes without overly reducing blood glucose in a subject; i.e., not reducing blood glucose in a fasting subject. The present invention also relates to an extract and composition of the overground part of Hedychium coronarium Koenig and its use in lowering blood glucose, increasing insulin levels and treating and / or preventing diabetes.

The invention discloses a tissue culture and rapid propagation method of flowerlet hedychium coronarium. The method comprises the following steps: pre-treating an explant, proliferating a bud base, inducing cluster buds, carrying out subculture proliferation, carrying out rooting and culturing sound seedlings, and exercising the seedlings and transplanting. The method comprises the specific steps:inoculating a disinfected bud base explant into a proliferation culture medium and culturing until a spherical shape is formed on the base of the explant; cutting the proliferated bud base and transferring the proliferated bud base to a cluster bud induced culture medium to induce the cluster buds; when subculture cluster bud seedlings are 4cm to 6cm high, cutting off the cluster buds and transferring the cluster buds to a sound seedling rooting culture medium and culturing; when the seedlings on the sound seedling rooting culture medium are 6cm to 8cm high, exercising the seedlings in a greenhouse under natural illumination for 7d to 10d; taking out the seedlings and washing the culture medium on roots; culturing to obtain transplanted seedlings. According to the tissue culture and rapidpropagation method disclosed by the invention, tissue culture seedlings capable of keeping good properties of stock plants can be obtained in a short period; the tissue culture and rapid propagationmethod has small damages to the stock plants and is low in investment and high in yield; a lot of flowerlet hedychium coronarium tissue culture seedlings can be provided.

The invention belongs to the technical field of gene engineering and particularly discloses a ginger flower floral specific and damage and pest induced TPS2 (Trehalose-6-Phosphate Synthase 2) promoter and an application thereof. The promoter has a nucleotide sequence as shown in SEQ ID NO: 2. A target gene controlled by the TPS2 promoter disclosed by the invention is only expressed in a flower tissue of a transgenic tobacco, and the expression is relevant to a flower development process and is induced by damage and pests. In addition, the TPS2 promoter disclosed by the invention can be introduced to a cell of a ginger flower or other plants after being connected to any one plant transformation vector to obtain promoter-containing transgenic fragrance and resistance to be used for production; or a specific molecular marker can also be generated according to the sequence information of the promoter disclosed by the invention and is used for authenticating the fragrance and resistance genotypes of the ginger flower or other plants and realizing the molecular-marker-assisted selective breeding, so that the breeding selection efficiency is increased.
