Objective: The aim of the study was to determine the content of polyphenols and flavonoids from sixteen selected medicinal plants from the spontaneous Romanian flora and fifteen tinctures obtained with propylene glycol.

Methods: The polyphenols were determined by the Folin-Ciocalteu method while the flavonoids by using a colorimetric method from the 10th edition of the Romanian Pharmacopoeia. The antioxidant activities of the most common nine medicinal plants and fifteen tinctures were determined by DPPH and ABTS methods.

Results: The results highlighted that the phenolic compounds and flavonoids have contributed to their antioxidant activities and the medicinal plants and tinctures included in the study are rich sources of natural antioxidants.

Conclusions: There are a wide variety of extraction methods for the determination of phenolics and flavonoids. The study confirms a correlation between phenolic and flavonoid contents obtained by using the DPPH and ABTS tests.


Polyphenolic compounds were determined from a pharmaceutical (tincture) and a cosmetic preparation (rose water), both obtained from the Rosae damascenae flores. Separation of the phenolic compounds was done by a HPLC method, using a Zorbax XDB or equivalent column C18, 250 mm x 4,6 mm; 5 μm. A gradient elution was performed with phosphoric acid and acetonitrile eluted under gradient conditions. The flow rate was 1.5 mL/min and the injection volume was 20 μL. HPLC method for determination of caftaric acid presented in this paper, has been validated. The results were statistically analyzed with SPSS 10 software.


Two-step targeted 2D planar chromatographic method (2DTLC) was used in the determination of ginkgolic acids in pharmaceuticals and dietary supplements. The choice of the extraction method and the separation technique was guided by the formulation type (capsule, tablet, tincture) with expected low amounts of ginkgolic acids in the analyzed herbal samples. Separation of ginkgolic acids C15:1 and C17:1 on HPTLC RP18 WF254s was preceded by its separation from the sample matrix on TLC Si60 F254s. Mobile phases consisted of acetonitrile/water/formic acid (80:20:1, V/V/V) and n-heptane/ethyl acetate/formic acid (20:30:1, V/V/V), resp. Identification of separated compounds was based on 2D-TLC co-chromatography with reference substances and off-line 2D-TLC x HPLC-DAD-ESI-MS analysis. Quantification of ginkgolic acids C15:1 and C17:1 was conducted densitometrically. Among the analyzed products, the presence of ginkgolic acids was confirmed only in herbal drugs containing 60 % ethanolic tinctures of Ginkgo biloba leaves. The use of TLC in the quantification of ginkgolic acids C15:1 and C17:1 in ginkgo extracts was described for the first time.


Primary hyperhidrosis affects approximately 3% of the world’s population, particularly young female adults. It is defined as excessive, profuse sweating of the palms, soles, armpits and face. Conservative treament includes diverse modalities, however, surgical treatment has shown the best long-term results. The objective of this study was to assess some disease-specific epidemiological characteristics in a pre-selected group of patients seeking surgical therapy, as well as outcomes of thoracoscopic sympathectomy. The severity and impact of hypehidrosis was assessed, using Hyperhidrosis Disease Severity Scale (HDSS: patients rate the serverity of symptoms on a scale from 1 to 4). Thoracoscopic sympathectomy was performed using a double lumen endotracheal tube, via bilateral 5 mm dual port videothoracoscopic camera 0°, and an endoscopic ultrasound activated harmonic scalpel. The sympathetic chain was resected on both sides at the level of the second and the third thoracic ganglion (T2 and T3), using an ultrasound knife. The extirpated chain was also at the level T3-T4 and sent for ex tempore analysis. There were 162 patients undergoing thoracoscopic sympathectomy: 39.51% were males and 60.49% females; at presentation their mean age (± SD) was 30.5 (±8.3), range 16 - 58 years. Axillary hyperhidrosis occurs later than palmar-axillary-plantar (p<0.05). A total of 35.18% of the evaluated patients were able to name at least one member of their families who also suffered from hyperhidrosis. The most commonly affected area was palmar-axillary-plantar (30.25%). Fifty patients (30.86%) received conservative therapy before surgery. The most commonly used conservative therapy modalities included different kinds of ointments/tinctures (11.73%), botox (8.02%) and iontophoresis (2.47%). Prior to surgery, 91.36% of patients reported severe sweating (HDSS score 3 or 4). The highest mean score was given for a combination of facial-palmar-axillaryplantar hyperhidrosis (3.80±0.24). All surgeries were successfully performed, with no complications, or perioperative morbidity. The mean hospital stay was 1.28±0.68 days long. After surgery, 93.21% of patients reported mild or moderate hyperhidrosis (HDSS score 1 or 2). Compensatory sweating (lower part of the back, and abdomen) was reported by 34.57% of patients after the surgery. All patients had a 6-months long follow-up: a significant improvement in quality of life was reported by 84.56% of patients (Yates corrected c2 (1) = 228.42; p=0.0000)); due to compensatory sweating, only 4.94% and 1.85% of patients reported bad and very bad quality of life, respectively.

In conclusion, nowadays videothoracoscopic sympathectomy is a standard treatment for primary hyperhidrosis with a high success rate.
