A method for producing full spectrum hemp extract comprising extracting substances from cannabis-based green material that are soluble in an extraction solvent and collecting an extract that includes the extraction solvent distilling at least a portion of the extraction solvent which results in a concentrate that is not distilled off, removing at least a portion of water soluble substances from the concentrate by partitioning the at least a portion of water soluble substances into an aqueous phase and a remainder of substances from the concentrate into a partitioned concentrate, heating the partitioned concentrate to evaporate the nonpolar solvent and to yield a crude oil, degassing the crude oil by heating it which results in a degassed crude oil, performing a first pass distillation at about 150° C. and collecting a first residue, performing a second and third pass distillation at about 170° C. and about 185° C., and collecting a distillate from same.

The invention relates to a polyphenolic extract of passion flower seeds, in particular Passiflora incarnata or Passiflora edulis seeds, comprising at least 30 percent by weight polyphenols, expressed as gallic acid equivalent, relative to the weight of the dry extract. The invention also relates to a method for preparing an extract of said type, a composition containing same, and the cosmetic, dermatological or therapeutic use thereof.

A method for preparing health foods having aloeswood. Preparing materials in which aloeswood, Saururus chinensis, Huperzia, white tea and Houttuynia cordata Thunb are each washed, and then dried in shade, pulverized and roasted. The roasted aloeswood, Saururus chinensis, Huperzia, white tea and Houttuynia cordata Thunb are mixed at a weight ratio of 4:1:1:1:1. The brewed and distilled aloeswood, Saururus chinensis and water mixture is mixed with the maturing an aloeswood, Saururus chinensis, Huperzia, white tea and Houttuynia cordata Thunb mixture and double boiled to prepare a leachate. The prepared leachate is extracted and concentrated, and then heat-matured to remove the moisture. The heat-matured extract is cool-dried, mixed with mineral water, then heated, dried at room temperature and molded into a predetermined shape. The prepared health foods having effects in preventing absorption of heavy metals in body and excreting the same from body.

The present invention describes a method which outlines a process for conversion of CBD to a Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the Δ.sup.9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% Δ.sup.9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce Δ.sup.9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% Δ.sup.9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the Δ.sup.9-THC using distillation and collecting an essentially pure fraction of Δ.sup.9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity Δ.sup.9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.

Provided is a method for extracting and refining alkaloids from ipecac, comprising: (1) grinding ipecac, adding acidic methanol/ethanol solution for extraction, obtaining an extraction solution A, concentrating under a reduced pressure, and obtaining a concentrated solution B; (2) using reversed-phase polymer filler J for adsorption, and performing desorption by washing with water, collecting a washing solution C, eluting with an alcoholic solution E and collecting a desorption solution D; (3) injecting the washing solution C and the desorption solution D into a preparative high performance liquid chromatograph for separation and purification respectively, to collect a solution G, and a solution H and a solution I respectively; and (4) concentrating the solutions G, H and I, which are then subjected to reversed-phase polymer filler K for adsorption respectively; eluting them respectively after adsorption with an alcoholic solution F; concentrating obtained eluates to dryness; and then performing vacuum drying.

A method for extracting flavone aglycones in Chrysanthemum morifolium is provided. The method includes: (a) immersing a Chrysanthemum morifolium raw material in water or an aqueous solution to perform an immersion procedure for 3.5 hours or more to obtain an immersion sample; and (b) adding an extraction solvent to the immersion sample to perform an extraction procedure 5-60 minutes to obtain an extract. The Chrysanthemum morifolium raw material includes at least one of the following parts of Chrysanthemum morifolium: whole plant, roots, stems, leaves and flowers.
