opium alkaloids

His research was chiefly on the constitution of alloys and opium alkaloids.

The last step is purifying and separating morphine from other opium alkaloids.

Structurally, it is similar to morphinan, the central core of the opium alkaloids.

Most often it is used to refer to opium alkaloids, and semi-synthetic opioids.

In this century, many synthetic drugs (opioids) have been developed with essentially the same effects as the natural opium alkaloids.

Poppy seeds do contain trace amounts of opium alkaloids, including morphine.

Tasmania is the world’s largest producer of legally grown opium alkaloids for the international pharmaceutical market.

Laudanum is known as a "whole opium" preparation since it historically contained all the opium alkaloids.

He also dedicated the opium alkaloids a series of works in 1917 and gave a method for the production of pure opium extracts.

Bob Arctor said, "It's black sticky hash, which means it's saturated with opium alkaloids."

Exports of chemical and related products (primarily opium alkaloids) totalled 79.34 million, or 3.3 per cent of total exports.

Pantopon (opium alkaloids hydrochlorides) and similar preparations have much of the advantages of whole opium in injectable form.

Papaveretum (BAN) is a preparation containing a mixture of hydrochloride salts of opium alkaloids.

Two years later he authored Opium Alkaloids: Selected Topics, published by Interscience Publishers.

While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic (morphine-related) opium alkaloids (opiates).

Other countries have fewer difficulties with permitting the growth of poppies for the seeds alone, which have very low (but still present) levels of opium alkaloids, such as morphine.

Unlike morphine, codeine or the other opium alkaloids, laudanum is an extract of whole opium latex, containing all of the narcotic compounds found in that sap.

Reddish-brown and extremely bitter, laudanum contains almost all of the opium alkaloids, including morphine and codeine, and its high morphine concentration makes it a potent narcotic.

Like poppy seeds, poppyseed oil is highly palatable, high in vitamin E, and contains opium alkaloids such as morphine and codeine in quantities of up to 400 mg/L.

The relative proportion of codeine to morphine, the most common opium alkaloid at 4% to 23%, tends to be somewhat higher in the poppy straw method of preparing opium alkaloids.

Calcium morphenate is a calcium salt of morphine which is produced by using calcium bases to raise the pH of an aqueous solution of opium alkaloids to around 9.0.

He was particularly noted for the total synthesis of heterocyclic drugs and natural products, including porphyrins, camptothecin, saxitoxin, psoralens, antibiotics, antitumor compounds, and opium alkaloids such as morphine, codeine, and hydromorphone.

Although the drug opium is produced by "milking" latex from the unripe fruits ("seed pods") rather than from the seeds, all parts of the plant can contain or carry the opium alkaloids, especially morphine and codeine.
