In total, 29 compounds from sweet wormwood (Artemisia annua L.) oil were identified using gas chromatography-mass spectrometry. The five active components were D-camphor, linalool, cineole, α-terpineol, and L(-)-borneol. The effectiveness of A. annua oil, as well as d-camphor, linalool, cineole, α-terpineol, and L(-)-borneol, as fumigants, contact insecticides, and repellents, were tested on th...
A. annua is so named because it is almost the only member of the genus with an annual cycle. It is a shrub, often growing over 2 m high (Ferreira et al., 1997; see Figure 3.1 and Figure 3.2). Its leaves and flowers contain artemisinin, first isolated in China in 1971; this is the constituent with the greatest antimalarial activity (see Table 3.3). Artemisinin has been found in only two other sp...
The clinical assays of Jerome Munyangi in RDC [1,2] following those of Patrick Ogwang in Uganda [3] have clearly shown that Artemisia annua has prophylactic properties against malaria, but it is not known how and why. Artemisia plants are rich in polyunsaturated fatty acids (PUFA) which generate prostaglandins and stimulate monocytes. PUFAs possess well documented antimalarial and prophylactic ...
Abstract The leaves of different species the genus Artemisia show considerable inner and external structural diversity. This paper presents a comparative study micromorphological features leaf surface for seven from regions Ukraine: A. absinthium L., annua dracunculus marschalliana Spreng., vulgaris argyi H.Lév. & Vaniot, verlotiorum Lamotte. vegetative organs these plants have potentially ...
Four new compounds obtained from cultured cells of Artemisia annua were reported. Products were detected by HPLC-ELSD/GC-MS and isolated by chromatographic methods. The structures of four new compounds, namely 6-hydroxy arteannuin I (1), 1-hydroxy arteannuin I (2), 2-hydroxy arteannuin J (3), and 14-hydroxy arteannuin J (4), were elucidated using their physico-chemical properties by NMR and MS ...
آرتمیزینین مادهای با خاصیت ضد مالاریایی است که در گیاه a. annua l. بهطور طبیعی وجود دارد. در این پژوهش تأثیر برخی از عوامل نظیر بافت خاک، تغذیه معدنی و ph محلول غذایی بر میزان تولید آرتمیزینین مورد بررسی قرار گرفت. بیشترین مقدار آرتمیزینین در خاک شنی لوم، با 065/0درصد و کمترین مقدار آن در خاک سیلت لوم، با 043/0 درصد مشاهده شد. کمترین مقدار آرتمیزینین تولید شده در محلول غذایی فاقد فسفر مشاهده ...
This article treats Chinese medical theories and concepts as cultural constructs that arose as much from practice-oriented concerns as from socio-political negotiations within the medical field. It further explores the interface of the biological and cultural. It is often futile to investigate how Chinese medical descriptions relate to biological processes, because the local biologies that the ...
