Isolation, Purification and Structure Elucidation of a Xanthone from the Pericarp of Kamandiis (Garcinia rubra Merr.)

Autor: Hidelisa P. Hernandez, Leon O. Namuco, Cherry Mae T. Ravidas, Teofila D.C. Villar

Publikováno v: KIMIKA. 30:40-44

The pericarp of Garcinia rubra, an endemic Garcinia species in the Philippines was extracted with dichloromethane. An isolate of the extract was acetylated giving monoacetyl and diacetyl derivatives. Analysis of these derivatives led to the elucidati

Preparation of nata de coco-based carboxymethylcellulose coating and its effect on the post-harvest life of bell pepper (Capsicum annuum l.) fruits

Autor: Veronica C. Sabularse, Edralina P. Serrano, Hidelisa P. Hernandez, Mary Nizza D Montalbo

Publikováno v: International journal of food sciences and nutrition. 60

Carboxymethyl cellulose from nata de coco, referred to as carboxymethyl-nata (CMN), was prepared by two cycles of mercerization and etherification. Coatings containing 1% and 2% CMN were applied on bell peppers to evaluate the effect of the polysacch

Foliage volatiles of two rice cultivars

Autor: Hidelisa P. Hernandez, Thomas C.-Y. Hsieh, C. Michael Smith, Nikolaus H. Fischer

Publikováno v: Phytochemistry. 28:2959-2962

Volatiles of two rice varieties (‘Mars’ and PI346833) were collected from seedlings by dynamic headspace sampling and trapping on Tenax TA. Thermal desorption and cryogenic focusing methods were used to introduce the volatiles onto the column for

Unambiguous Structure Determination of a New Flavonoid, 5,6,4′-Tnriydroxy-7,8,3′-Trimethoxyflavone, by the Use of INAPT NMR Techniques

Autor: Nikolaus H. Fischer, Hidelisa P. Hernandez

Publikováno v: Spectroscopy Letters. 21:927-934

The structure elucidation of a new flavone, 5,6,4′-trihydroxy-7,8,3′-trimethoxyflavone, was performed by the use of Insensitive Nuc1ei Assigned by Polarization Transfer (INAPT), a simple and sensitive NMR technique. Application of INAPT allowed t
