Oplodiol
Oplodiol exhibits noteworthy anti-plasmodial activity against Plasmodium falciparum strains. Oplodiol has a stimulative effect on significantly proliferation and differentiation of culture osteoblasts; it also shows moderate cytotoxic effects on the human lung adenocarcinoma A549 with IC50 values at 25.5 ug/mL.

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
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 sesquiterpenoid from the rhizomes of Homalomena occulta.[Pubmed:
25104218]
METHODS AND RESULTS:
Chemical constituents of EtOAc extract from the rhizomes of traditional Chinese medicine Qian-nian-jian (Homalomena occulta) have been studied, a new sesquiterpenoid, named euadesma-4-ene-1β,15-diol (1), and four related known compounds, polydactin B (2), Oplodiol (3), 1β,4β,7α-trihydroxyeudesmane (4), and (-)1β,4β,6α-trihydroxy-eudesmane (5), were isolated. Their structures were elucidated using spectroscopic methods including 1D and 2D NMR techniques and mass spectrometry. All the isolates were tested against the human lung adenocarcinoma A549 using MTT assay method.
CONCLUSIONS:
Oplodiol (3) and (-)1β,4β,6α-trihydroxy-eudesmane (5) were found to show moderate cytotoxic effects on A549 with IC50 values at 25.5 and 15.0 μg/mL, respectively.

Sesquiterpenes from the roots of Illicium oligandrum.[Pubmed:
25966312]
METHODS AND RESULTS:
Two new sesquiterpenes, oligandrin (1) and oligandric acid (2), together with three analogues, tashironin A (3), tashironin (4), and Oplodiol (5), were isolated from the roots of Illicium oligandrum. The structures of new compounds were determined based on 1D and 2D NMR experiments and X-ray diffraction. Compound 1 represents a presumed biosynthetic precursor of seco-prezizaane sesquiterpenes which consists of a novel 6/6/5 tricarbocyclic skeleton. Compound 2 is the first example of chamipinene-type sesquiterpene possessing a 6/4/6 tricyclic system from the genus Illicium. Compounds 1-5 were evaluated in vitro for their activity against coxsackie virus B3 (CVB3), influenza virus A/Hanfang/359/95 (H3N2), and influenza virus A/FM/1/47 (H1N1).
CONCLUSIONS:
Compound 1 showed selective antiviral activity against CVB3 with IC50 value of 11.11 μM.

Anti-plasmodial sesquiterpenoids from the African Reneilmia cincinnata.[Pubmed:
10643672]
METHODS AND RESULTS:
A new isodaucane sesquiterpenoid, 6,7,10-trihydoxyisodaucane, was isolated from the fruits of Reneilmia cincinnata, together with the known sesquiterpenoids Oplodiol, oplopanone, 5E,10(14)-germacradien-1 beta, 4 beta-diol, 1(10)E,5E-germacradien-4 alpha-ol and eudesman-1,4,7-triol. A large amount of 5-hydroxy-3,7,4'-trimethoxyflavone was also isolated. Their structures were established by NMR techniques using 1D and 2D experiments.
CONCLUSIONS:
Three of the known sesquirernenoids exhibited noteworthy anti-plasmodial activity against Plasmodium falciparum strains.

Sesquiterpenoids from Homalomena occulta affect osteoblast proliferation, differentiation and mineralization in vitro.[Pubmed:
18649899 ]
METHODS AND RESULTS:
Chemical investigation of rhizomes of Homalomena occulta (Lours) resulted in isolation and identification of two sesquiterpenoids (6,7), and one daucane ester 8, together with five known sesquiterpenoids, Oplodiol, oplopanone, homalomenol C, bullatantriol, and 1beta,4beta,7alpha-trihydroxyeudesmane. Their structures were elucidated using 1D and 2D NMR spectroscopic and X-ray analyses. The chloroform extract of this plant and compounds 1-7 were tested in vitro for their activities in stimulating osteoblast (OB) proliferation, differentiation and mineralization.
CONCLUSIONS:
Compounds 1-4 had a stimulative effect on significantly proliferation and differentiation of culture osteoblasts, while the chloroform extract and 1 significantly stimulated mineralization of cultured osteoblasts in vitro
