“…Comparatively high levels of quercetin derivatives have been quantified in chamomile tea (Nováková et al, 2010). In contrast, Raal et al (2012) reported their share in a range from 0.29% to 1.21% TAPs in infusions from commercial German chamomile. As mentioned previously, flavonols represented from 20% to 60% TAPs in elderflower infusions analyzed in the present study.…”

associated with yield (number and size of inflorescences), chemical composition of inflorescences, growth characteristics, uniformity of flowering, and resistance to pests and diseases. Our studies indicate that interspecific hybridization efficiently increases the variation in the chemical composition of elderberry fruits (Mikulic-Petkovsek et al., 2014.Polyphenolic compounds are regarded as important chemical compounds due to their high antioxidant efficacy (Ozgen et al., 2010), which has a positive impact on people's health, and may impede the development of cancer and inhibit oxidative damage (Akbulut et al., 2009). Phenolic compounds possess various pharmacological effects: antiviral, antibacterial, antiinflammatory, and anticancer functions. Positive effects of flavonoids and phenolic acids have also been reported in connection with cardiovascular diseases (Olthof et al., 2001;Netzel et al., 2002;Murkovic et al., 2004). It has been reported that the concentration of phenolics is closely connected with the antioxidant activity of plant tissue and thus an assessment of the phenolic profile is important for the determination of antioxidant capacity (Choi and Kwak, 2014). The antioxidant activity of elderberry inflorescence extracts ranged from 44.8 to 118.2 mM TE/kg DW (Mikulic-Petkovsek et al., 2016).

“…Besides the extraction techniques many other factors may play role in the biological activity of chamomile, including climatic and seasonal changes, harvest time, and storage conditions, whereas the major bioactive compound possessing anticancer activity in chamomile extract might be apigenin (Srivastava & Gupta, 2009). Commercial samples of chamomile tea from Estonia and other countries contained 0.4-9.3 mg of apigenin glucoside and 0-1.5 mg apigenin acetylglucoside per cup (200 ml) of tea (Raal et al, 2012). Apigenin glucoside was also found (1.4-8.3 mg/ml) in Chamomilla suaveolens (Pursh) Rydb.…”

Context: Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. Objective: To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Methods: Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA (http://herba.folklore.ee/), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies.

Botanic matrices are abundant sources of antioxidants which have the capacity to avoid the lipid o xidation of food and present remarkab le health benefits. The natural antioxidants might be obtained applying many extraction techniques. Satisfactory results of obtaining extracts with antio xidant properties and high yields using modern extraction techniques are shown by recent studies. The selection of the suitable technique depends on the desired class of substances to be extracted. In this overview, the advances reached in scientific researches involving natural antio xidants are presented. The advantages and potential applicat ions of four novel ext raction techniques: Supercritical Flu id Ext raction, Pressurized Liquid Extraction, M icro wave Assisted Extraction and Ultrasound Assisted Extraction are discussed, considering the characteristics of the target compounds. These techniques reduce the solvent consumption and abridge the extraction time. Consequently, the process productivity is increased.
