DETAILED DESCRIPTION

[0031] Rebaudioside F is a naturally occurring steviol glycoside whose structure is shown in Figure 1. Rebaudioside F is structurally similar to rebaudioside A, differing only in the presence of a xylose in place of a glucose. This difference is shown graphically in Figure 2. Despite this structural similarity, rebaudioside F surprisingly lacks the sweetening qualities of rebaudioside A. For example, a 300 ppm rebaudioside A solution has a sweetness that is equivalent to an approximately 6% to 8% sugar solution. By contrast, rebaudioside F at 300 ppm is only about as sweet as a 3% sugar solution. [0032] It has been surprisingly found, however, that although rebaudioside F is not a high potency sweetener like rebaudioside A or M, it can enhance the sweetness of certain other sweeteners. And when used as a sweetness enhancer, rebaudioside F enables reducing overall sweetener concentration in a given product.

Rather, the embodiments should be construed to encompass any and all variations which become evident as a result of the teaching provided herein.

Example 1 : Evaluation of Sweetening Enhancement in Forced-Choice Test

[0116] A 300 ppm rebaudioside A solution was prepared by dissolving 30 mg of

rebaudioside A in 100 mL of pH 3.1 water (phosphoric acid) at room temperature.

[0117] A 4° Brix HFCS solution was prepared by dissolving 50.89 g of 78.60 °Brix

HFCS in 1000 g phosphoric acid base prepared by adding phosphoric acid drop-wise into 1 L of AQUAFINA water until the pH was 3.1.

[0118] Fructose, glucose, sucralose, and aspartame solutions including the amount of sweetener specified in Table 1 were prepared by weighing the appropriate amount of sweetener and dissolved it at room temperature in pH 3.1 water (phosphoric acid).

Table 1

[0119] Tasting protocol: 13-18 tasters were provided with a first liquid sample containing a given volume of an aqueous solution of rebaudioside A, FIFCS, fructose, glucose, sucralose, or aspartame, all prepared as described above, and in the concentrations noted in Table 2. Tasters were also provided with an otherwise identical sample also containing rebaudioside F at the concentration shown in Table 2. Tasters were asked to determine which sample tasted sweeter. Tasters did not eat at least 1 hour before tasting and rinsed with AQUAFINA water at least 5 times between tasting each sample. Tasters wore nose clips and were blinded to the identity of the test material. The results of this study are shown in Table 2.

Table 2

[0120] As shown in Table 2, a majority of tasters reported that rebaudioside F enhanced the sweetness of HFCS, fructose, glucose, sucralose, and aspartame. All testers reported that adding 90 ppm rebaudioside F to a 4 °Brix HFCS solution resulted in the solution having enhanced sweetness relative to the solution without rebaudioside F. All testers likewise reported that adding 60 ppm rebaudioside F to a sucralose solution equi-sweet to a 5 °Brix sucrose solution resulted in the solution having enhanced sweetness relative to the same solution without rebaudioside F.

[0121] Surprisingly, rebaudioside F only minimally enhanced the sweetness of a 300 ppm rebaudioside A solution. Without wishing to be bound by a particular theory, it is believed that rebaudioside F's effectiveness was reduced in this solution because rebaudioside F and rebaudioside A bind to the same sweet taste receptors and

rebaudioside A bound to the receptor preferentially.

Example 2: Evaluation of Magnitude of Sweetening Enhancement

[0122] Percent sweetness enhancement is evaluated as follows: Four samples were

prepared: (1) a 25% reduced sweetener control sample (without rebaudioside F) is prepared; (2) a 50% reduced sweetener control sample without rebaudioside F is prepared; (3) a test sample with (either solution 1 or solution 2) with a known quantity of rebaudioside F is prepared; and (4) a benchmark sample containing a "high

concentration" of the sweetener used in the control samples (two times the concentration of the 50% reduced sweetener control sample) is prepared. Samples are evaluated in a system containing phosphoric acid, pH=3.1, or citric acid of similar pH.

[0123] Tasters, wearing nose clips, are then provided with a portion of each of the four samples and asked to rank the four samples in order of sweet intensity, from low sweet to high sweet. Samples are evaluated in triplicate. The amount of enhancement is estimated based on the rank order of the samples and are analyzed with Friedman's Test, followed by Tukey's.

Example 3 : Isolation of Rebaudioside F - Method 1

[0124] Stevia rebaudiana extract (procured from TianJin Tianping Biotech Co. Ltd.) containing 0.18% rebaudioside F as determined by UV detection at 210nm was dissolved in methanol at approximately 200 mg/mL and allowed to crystallize. The crystalized material was separated via filtration and discarded but the mother liquor was retained. 350 g of the mother liquor, containing about 1.44% rebaudioside F, was then adhered onto 450 g of silica gel and loaded on top of a normal phase column (200x200 mm length) packed with an additional 1 kg of 100-200 mesh silica gel. Fractions were eluted using CH ₂ Cl ₂ :MeOH:H ₂ 0 (100:0:0, 100:9.5:0.5, 100: 19: 1, 100:47:3, 0:80:20) and 3L were collected in fractions. Fractions containing rebaudioside F (LCMS) were combined and all volatiles were removed under reduced pressure to give about 120 g of a material enriched in rebaudioside F.

[0125] The material enriched in rebaudioside F was dissolved in H ₂ 0, and a 120g sample was subject to prep-HPLC on an MPLC-C18 column (MPLC Buchi C620,

chromatography column ODS (Yamazen ODS-C18 500x80 mm, 40-60 μιη)). The mobile phase was acetonitrile:water containing 0.1% TFA. Fractions containing rebaudioside F were pooled and solvent was evaporated to yield 45g of crude material containing about 2.36% rebaudioside F.

[0126] The crude material (45 g) was then dissolved in H ₂ 0 and chromatographed again using the MPLC-C18 column (MPLC Buchi C620, chromatography column ODS (Yamazen ODS-C18 500x80 mm, 40-60 μιη)). The mobile phase was

acetonitrile(A):water(B) containing 0.1% TFA and the sample was eluted using the following gradient: 20% B for 2 min, 20-100% B over 45 min, and 100% B for 15 min. The flow rate was 100 mL/min. Fractions containing rebaudioside F were pooled and solvent was evaporated to yield 15 g of a further refined sample containing ~3.5%-4.5% rebaudioside F.

[0127] The further refined sample was dissolved in H ₂ 0, and 1 g aliquots were injected, and separated, by prep-HPLC (prep-FIPLC, SHIMADZU, chromatography column ODS (Daiso C18 300x50.0mm, ΙΟμπι)). The mobile phase was acetonitrile(A):water(B) containing 0.1% TFA and the sample was eluted using the following gradient: 20% B for 2 min, 20-40% B over 20 min, and 95% B for 3 min. The flow rate was 80 mL/min. Fractions containing rebaudioside F were pooled and solvent evaporated to give 3 g of material comprising about 15% to 22% rebaudioside F.

[0128] The material comprising about 15% to 22% rebaudioside F was then dissolved in

H ₂ 0, and 30 mg aliquots were injected, and separated, by semi-prep-HPLC (semi- preparative-HPLC, Gilson 281, chromatography column ODS (Luna C18 100x30.0mm, 5μπι)). The mobile phase was acetonitrile(A):water(B) containing 0.1% TFA and the sample was eluted using the following gradient: 15-35% B over 11 min, 35% B for 2 min, and 100%) B for 2 min. The flow rate was 25 mL/min. This procedure resulted in material comprising about 75% to 90% pure rebaudioside F.

[0129] In a final purification step, the material comprising about 75% to 90%

rebaudioside F was dissolved in H ₂ 0 and subjected to semi-prep-HPLC ((semi- preparative-HPLC, Gilson 281, chromatography column ODS (Luna C18 100x30.0mm, 5μιη)) using acetonitrile(A):water(B) containing 0.1% TFA and the sample was eluted using the following gradient: 15-35% B over 11 min, 35% B for 2 min, and 100% B for 2 min. The flow rate was 25 mL/min. Fractions containing rebaudioside F were pooled and solvent evaporated to yield highly pure rebaudioside F (369 mg; ~92%-98% as determined by UV detection at 210nm).

Example 4: Isolation of Rebaudioside F - Method 2

[0130] Stevia rebaudiana (TianJin Tianping Biotech Co. Ltd.) extract containing about

0.79%) rebaudioside F as determined by UV detection at 210nm, was dissolved in MeOH and chromatographed by normal phase chromatography via twenty large-scale column runs. For each run, 1.5 kg of stevia extract was adhered onto 2 kg of silica gel and loaded on top of a normal phase column ( 200x200 mm length) packed with an additional 1 kg of 100-200 mesh silica gel. Fractions were eluted using CH ₂ Cl ₂ :MeOH:H ₂ 0 (100:0:0, 100:9.5:0.5, 100: 19: 1, 100:47:3, 0:80:20) and 7L fractions were collected. The fractions were analyzed by LCMS. Fractions containing rebaudioside F were combined and all volatiles were removed under reduced pressure to give about 20 kg of material containing about 0.89%) rebaudioside F as determined by UV detection at 210nm.

[0131] 5 kg of the material containing about 0.89%> rebaudioside F was dissolved in 25L

H ₂ 0, and 250 g samples were subject to prep-MPLC on an MPLC-C18 column chromatography (MPLC Buchi C620, chromatography column ODS (Yamazen ODS-C18 500x80 mm, 40-60 μιη)). The mobile phase was acetonitrile(A):water(B) containing 0.1%) TFA and the sample was eluted using the following gradient: 20%> B for 2 min, 20- 100% B over 45 min, 100-100% B for 15 min. The flow rate was 90mL/min. Fractions containing rebaudioside F were pooled and solvent evaporated to yield 3 kg of crude refined sample containing about 3.61% rebaudioside F.

[0132] The crude material was again dissolved in a minimum amount of H ₂ 0, and 50 g samples were injected, and separated by prep-MPLC-C18 column chromatography (MPLC Buchi C620, chromatography column ODS (Yamazen ODS-C18 500x80 mm, 40-60 μπι)). The mobile phase was acetonitrile(A):water(B) containing 0.1%> TFA and the sample was eluted using the following gradient: 20%> B for 2 min, 20-100%) B over 45 min, and 100% B for 15 min. The flow rate was 90 mL/min. Fractions containing rebaudioside F were pooled and solvent was removed to yield 2 kg of a further refined sample containing about 4.5% to 6.5% rebaudioside F.

[0133] The further refined sample was dissolved in a minimum amount of H ₂ 0, and 1 g sample aliquots were injected, and separated, by prep-HPLC (prep-HPLC, SHIMADZU, chromatography column ODS (Daiso C18 300x50.0mm, ΙΟμπι)). The mobile phase was Acetonitrile(A):water(B) with 0.1% TFA and the sample was eluted using the following gradient: 20% B for 2 min, 20-35% B over 15 min, 35% B for 5 min, and 95% B for 3 min. The flow rate was 80mL/min. Fractions containing rebaudioside F were pooled and solvent was evaporated to give 400 g of material containing about 13% to 23% rebaudioside F.

[0134] The material comprising about 13% to 23% rebaudioside F was dissolved in H ₂ 0, and 1 g aliquots were injected, and separated, by prep-FIPLC (prep-HPLC, SHIMADZU, chromatography column ODS (Daiso C18 300x50.0mm, ΙΟμπι)). The mobile phase was acetonitrile(A):water(B) with 0.1% TFA and the sample was eluted using the following gradient: 20% B for 2 min, 20-35% B over 15 min, 35% B for 5 min, and 95% B for 3 min. The flow rate was 80 mL/min. Fractions containing rebaudioside F were pooled and solvent was evaporated. This procedure resulted in material comprising about 50% to 70%) rebaudioside F.

[0135] In a final purification step, the material comprising about 50% to 70%

rebaudioside F was dissolved in H ₂ 0, and 200 mg aliquots were injected, and separated, by prep-HPLC (prep-HPLC, SHIMADZU, chromatography column ODS (Daiso CI 8 300x50.0mm, ΙΟμηι)). The mobile phase was acetonitrile(A):water(B) with 0.1% TFA and the sample was eluted using the following gradient: 20% B for 2 min, 20-35% B over 15 min, 35% B for 5 min, and 95% B for 3 min. The flow rate was 80 mL/min. Fractions containing rebaudioside F were pooled and solvent was evaporated to yield high-purity rebaudioside F (90-98%; as determined by UV detection at 210 nm).
