Kvantitativna analiza fenolnih spojeva ljepljivog omana – Inula viscosa (L.) Ait.
The quantitative analysis of phenolic compounds (phenolic
acids, flavonoids, total polyphenols, nontannic polyphenols and tannins) was
carried out in the samples of stems, leaves and flowers of Inula viscosa. The content
of all investigated compounds was determined using spectrophotometric
methods. The quantity of phenolic acids ranged from 1.71 to 5.92%, while the
content of flavonoids varied between 0.157 and 0.498%. The leaves contained
the highest quantity of phenolic acids. The content of total polyphenols ranged
from 4.56 to 11.30%. The quantity of polyphenols unadsorbed on hide powder
(nontannic polyphenols) was between 2.65 and 7.37% while the quantity of tannins
ranged from 1.91 to 3.93%. Statistical analysis was assessed by Student's t-
-test. The content of all investigated compounds depended on the plant organ and
climatic factors

Gutaperka - obilježja i primjena u dentalnoj medicini
Gutta-percha is the rigid natural latex produced from the plant species Palaquium
gutta (Hook.) Burck (Sapotaceae). It is a polyterpene, a polymer of isoprene, or
polyisoprene, specifi cally trans-polyisoprene. Gutta-percha remains to be the main
core material used for root canal fillings in dentistry. It has unique property of inertness,
better sealing ability and the ability to do retreatment in case of failure, makes
it an indispensable obturating material currently
Divlja šparoga (Asparagus acutifolius L.) – botanički podaci, kemijski sastav i uporaba
Botanical data, chemical composition and use of the wild asparagus (Asparagus
acutifolius L.) are presented in this paper. Wild asparagus is rich in various minerals and vitamins, especially vitamin C
and folic acid, as well as many flavonoids, making it suitable for many types of usage.
Its fresh sprouts are among the richest sources of glutathione, one of the strongest
natural antioxidants, while dried flowers contain high content of flavonoids rutin and
quercetin, making wild asparagus beneficial to blood vessel protection. It is commonly
used among pregnant women due to its positive effect on lactation and the
important role of folic acid in the proper fetal development. Furthermore, wild asparagus
is regarded as a strong diuretic, making it appropriate for toxin elimination and
detoxification
Flavonoids of Guiera senegalensis J. F. GMEL. − thin-layer chromatography and numerical methods
The efficiency of seven thin-layer chromatographic systems for separating nine flavonoids isolated from Guiera senegalensis J. F. GMEL. (Combretaceae) was investigated. For this purpose, three mathematical techniques were applied. The first technique was the calculation of the information content derived from Shannon’s equation for each chromatographic system. In the second technique, the discriminating power of the systems was measured individually and in various combinations. The third technique classifies chromatographic systems according to clusters. The classification was carried out by the numerical taxonomy methods. The most suitable chromatographic systems for the separation of the investigated flavonoids are: ethyl acetate : ethylmethylketon : formic acid : water, 60:15:3:2, and ethyl acetate : formic acid : acetic acid : water, 100:11:11:27

Pripravci ljekovitih biljaka u liječenju kožnih bolesti
Botanical data, chemical composition and use of the most common medicinal
plants preparations in the treatment of skin diseases are presented in this article.
These plants include: Oenothera biennis, Borago officinalis, Avena sativa, Lavandula
angustifolia, Cocos nucifera, Matricaria recutita, Hamamelis virginiana and Olea europaea,
that are used for the treatment of various skin diseases such as atopic dermatitis,
psoriasis vulgaris, ichtyosis non-bullosa, or eczema craquelé. Even today, in the era of
highly specialized medicine, medicinal plant preparations are still used in dermatology
especially in the treatment of inflammatory and itchy skin conditions. Patients
trust and believe in beneficial effect of natural products, such as marigold or comfrey
ointment. However, caution is needed in persons with history of allergic reactions or
atopy, since plants can cause allergic or irritative inflammatory reactions in such individuals.
Recent literature data confirm existing interest in the medicinal plants usage
in dermatology
