Uses
Different sources of media describe the Uses of 17912-87-7 differently. You can refer to the following data:
1. It was isolated from the leaves of Myrtus communis
an inhibitory activity against nifuroxazide, aflatoxine B1 and H2O2 induced mutagenicity. Antioxidant
2. It was isolated from the leaves of Myrtus communis; shows antimutagenic activity. Myricitrin was a very potent radical scavenger with an IC50 value of 1.4 .mu.g/mL. Moreover, this compound induced an inhibitory activity against nifuroxazide, aflatoxine B1 and H2O2 induced mutagenicity. Antioxidant.
3. Myricitrin may be used as an analytical reference standard for determination of the analyte in Folium Rhododendri Micranthi extract using high-performance liquid chromatography. It may also be used as an external standard in the validation of both commercial herbal medicines and crude material of Myrcia uniflora extracts using high-performance liquid chromatography technique.
Definition
ChEBI: A glycosyloxyflavone that consists of myricetin attached to a alpha-L-rhamnopyranosyl residue at position 3 via a glycosidic linkage. Isolated from Myrica cerifera, it exhibits anti-allergic activity.
General Description
Produced and qualified by HWI pharma services GmbH.Exact content by quantitative NMR can be found on the certificate.
Biochem/physiol Actions
The metabolite myricitrin, 3-O-rhamnoside of myricetin, is found in plants, e.g. in the bark of Myrica esculenta (Myricaceae) and in the leaves of Myrica gale and in Chrysobalanus icaco. It is a feeding stimulant for some leaf beetles; and shown to have strong antioxidant activity against DPPH. Myricitrin may be of potential interest in the management of inflammatory conditions, and could constitute an attractive molecule of interest for the development of new analgesic drugs. Myricitrin is a nitric oxide (NO) and protein kinase C (PKC) inhibitor that has central nervous system activity, including anxiolytic-like action.
Check Digit Verification of cas no
The CAS Registry Mumber 17912-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,1 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17912-87:
(7*1)+(6*7)+(5*9)+(4*1)+(3*2)+(2*8)+(1*7)=127
127 % 10 = 7
So 17912-87-7 is a valid CAS Registry Number.

Acylated flavonols from Crocosmia crocosmiiflora
Asada, Yoshihisa,Hirayama, Yutaka,Furuya, Tsutomu
, p. 1497 - 1501 (2007/10/02)
Two new acylated flavonols, montbretins A and B were isolated from the corms of Crocosmia crocosmiiflora. Their structures were established as myricetin 3-O-[β-d-glucopyranosyl(1→2)-6-O-caffeoyl-β-d-glucopyranosyl (1→2)-α-l-rhamnopyranoside]-4′-O-[α-l-rhamnopyranosyl(1→4)-β-d-xylopyranoside] and 3-O-[β-d-glucopyranosyl (1→2)-6-O-p-coumaroyl-β-d-glucopyranosyl(1→2)-α-l-rhamnopyranoside]-4′-O-[α-l-rhamnopyranosyl(1→4)-β-d-xylopyranoside] by spectral and chemical methods.
