7alpha,20-epoxy-ent-kauranoids from Isodon parvifolius.[Pubmed: 16643043 ]

METHODS AND RESULTS:
Nine new 7alpha,20-epoxy-ent-kaurane diterpenoids, parvifolines C-K (1-9), together with 12 known analogues, rabdoternin G (10), adenolin E (11), lasiodonin (12), lushanrubescensin F (13), parvifoliside (14), effusanin A (15), Effusanin B (16), effusanin E (17), taibaihenryiin A (18), shikokianin (19), maoyecrystal J (20), and the acetonide of lasiodonin (21), were isolated from the leaves of Isodon parvifolius.
CONCLUSIONS:
The structures of compounds 1-9 were determined on the basis of spectroscopic methods including extensive 1D and 2D NMR analysis. The new diterpenoids (1-9) and lasiodonin (12) were evaluated for their inhibitory activity against A549, HT-29, and K562 cell lines.
Effusanin B Description
Source: The herbs of Isodon japonicus
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

A new diepoxy-ent-kauranoid, rugosinin, from Isodon rugosus.[Reference: WebLink]

METHODS AND RESULTS:
A new diterpenoid, rugosinin (1), isolated from Isodon rugosus, with absolute configuration was proved by single-crystal X-ray diffraction analysis, to be the member of a rare class of C-20/C-7 and C-20/C-14 diepoxy- ent-kauranoids. Effusanin A (2), Effusanin B (3), effusanin E (4), lasiokaurin (5) and oridonin (6) were found as known constituents of the genus Isodon with C-20/C-7 epoxy function.
CONCLUSIONS:
These compounds have exhibited DNA-damaging activity in assay which employed DNA-repair deficient (RAD 52Y) and repair proficient (RAD +) yeast strains.

Structures of effusanins, antibacterial diterpenoids from Rabdosia effusa[Reference: WebLink]

METHODS AND RESULTS:
Five new diterpenoids, effusanin A, Effusanin B, effusanin C, effusanin D and effusanin E with antibacterial activity were isolated from the stem and leaves of Rabdosia effusa and their structures were deduced from chemical and spectral findings.
