Strain NRRL 12292T, which produces the bleomycin-like antibiotics LL-BO1208 alpha and LL-BO1208 beta, forms umbels consisting of chains of smooth-surface ovoid spores that are borne on verticils on the serial mycelia, indicating that it is a member of the verticillate group of the genus Streptomyces formerly classified in the genus Streptoverticillium. This strain was compared morphologically a...

Achillea millefolium and Achillea ptarmica are both plants belonging to the Asteracea family and are traditionally used for their medicinal properties. It has already been shown that some N-alkylamides (NAAs) are responsible for these pharmacological actions. Therefore, in the present study, the NAA content of the two plants was analytically characterised. Different extracts were prepared from ...

In completion of our studies on Achillea exudate flavonoids, 11 alpine species of Achillea sect. Ptarmica were analyzed for their aglycone profiles. The study focuses on species commonly associated with A. moschata. The major flavonoid constituents found in exudates of most taxa were 6-hydroxyflavonol 3,6,4'-trimethyl ethers, except in A. ageratifolia and its subspecies, which are characterized...

The Achillea millefolium L. (Yarrow) is a common herb which is widely being used, worldwide. Achillea is being used for treatment of many disorders since centuries. It is considered safe for supplemental use and flavonoids such as kaempferol, luteolin and apigenin are of main constituents present in Achillea. Most of both antioxidant and anti-inflammatory properties of this herb have been attri...

Achillea L. (Compositae or Asteraceae) is a widely distributed medicinal plant throughout the world and has been used since ancient time. Popular indications of the several species of this genus include treatment of wounds, bleedings, headache, inflammation, pains, spasmodic diseases, flatulence and dyspepsia. Phytochemical investigations of Achillea species have revealed that many components f...

The chemical composition of the essential oils of Achillea holosericea, Achillea taygetea, Achillea fraasii was determined by GC/MS analysis. Among the ninety-five assayed constituents, camphor, borneol and 1,8-cineol were found to be the major components. The in-vitro antimicrobial activity of these essential oils was evaluated against six bacteria indicating that the first is totally inactive...

In the past two decades, increasing consumption of synthetic drugs and its associated side effects has led World Health Organization (WHO) to study the antioxidant activity of this plant. It also conducted an ethno botanical survey of endemic medicinal plants studying its uses by the rural populations in order to prevent and treat many current diseases (1). Achillea species such as Achillea mil...

According to distribution of genus Achillea, two main centers of diversity occur in S.E. Europe and S.W. Asia. Diversified essential oil compositions from Balkan Peninsula have been numerously reported. However, report on essential oils of Achillea species growing in Turkey, which is one of the main centers of diversity, is very limited. This paper represents the chemical compositions of the es...

OBJECTIVE Achillea is a traditional medicinal herb which contains different phenol and flavonoid compounds that are responsible for Achillea pharmacological effects. We aimed to determine phenol and flavonoid contents, besides antioxidant activities of different extracts from Achillea eriophoraa (A. eriophora) DC. and Achillea biebersteinii (A. biebersteinii) Afan. (endemic species in Iran) and...
