|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Structural revisions of blumenol C glucoside and byzantionoside B.[Pubmed: 20190461 ]|
|The absolute stereochemistry of Blumenol C glucoside and byzantionoside B was revised here as (6R,9S)- and (6R,9R)-9-hydroxymegastigman-4-en-3-one 9-O-beta-D-glucopyranosides, respectively, by modified Mosher's method. The empirical rules of (13)C-NMR chemical shift to determine the absolute stereochemistry of C-9 of 9-hydroxymegastigmane 9-O-beta-D-glucopyranoside were also discussed.|

|[Chemical constituents from the seed coat of Juglans regia].[Pubmed: 22860453]|
|Fifteen compounds were isolated from the seed coat of Juglans regia by silica gel, MCI gel and Sephadex LH-20 gel column chromatography, as well as high preparative performance liquid chromatography. Their structures were identified as salidroside (1), (6S, 9S)-roseoside (2), (6S, 9R)-roseoside (3), Blumenol C glucoside (4), byzantionoside B (5), 5-hydroxy-2-methoxy-1, 4-naphthoquinone (6), gallic acid (7), glycerol 1-(9Z-octadecenoate)-2-(9Z, 12Z-octadecadienoate)-3-(9Z, 12Z, 15Z-octadecatrienoate) (8), glycerol 1, 2, 3-tri-(9Z, 12Z-octadecadienoate) (9), glycerol 1, 2, 3-tri-(9Z, 12Z, 15Z-octadecatrienoate) (10), glycerol 1-hexadecanoate-2, 3-di-(9Z, 12Z-octadecadienoate) (11) on the basis of EI-MS, FAB-MS and NMR spectra. Moreover, 35 volatile compounds were identified by GC-MS.|

|[Chemical constituents from Faeces bombycis].[Pubmed: 19149256]|
|OBJECTIVE: To study the chemical constituents from Faeces bombycis. METHOD: Isolation and purification were carried out on silic gel, Sephadex LH-20 and RP-18 column chromatography. The chemical structures of the constituents were elucidated on the basis of physicochemical properties and spectral data. RESULT: Fifteen compounds were identified as 3S, 5R-dihydroxy-6R, 7-megstigmadien-9-one (1), 3S, 5R-dihydroxy-6S, 7-megstigmadien-9-one (2), (6R, 9R)-3-oxo-alpha-ionol-beta-D-glucopyranoside (3), (6R, 9S)-3-oxo-alpha-ionol-beta-D-glucopyranoside (4), Blumenol C glucoside (5), byzantionoside B (6), alangionoside L (7), lutein (8), pipecolic acid (9), betaine (10), alanine (11), glutamic acid (12), phenylalanine (13), leucine (14), isoleucine (15). CONCLUSION: All the compounds were separated from Faeces bombycis for the first time.|
