Alkaloids of Papaver orientale L
Journal of Pharmaceutical Sciences
|July 1, 1977
Summary
Five chemotypes of Papaver orientale L. were identified based on alkaloid profiles, with oripavine consistently being the major or sole alkaloid across all classifications.
Area of Science:
- Pharmacognosy
- Plant Chemistry
- Botany
Background:
- Papaver orientale L. is a plant species known for its potential medicinal properties.
- Alkaloid composition can vary significantly within plant species, influencing their chemical and biological profiles.
Purpose of the Study:
- To classify the chemotypes of Papaver orientale L. based on their distinct alkaloid profiles.
- To identify the specific alkaloids present in each chemotype and determine their relative abundance.
Main Methods:
- Analysis of alkaloid profiles in Papaver orientale L. samples.
- Classification of plants into chemotypes based on identified alkaloids.
- Determination of haploid chromosome number.
Main Results:
- Five distinct chemotypes (A, B, C, D, E) of Papaver orientale L. were identified, characterized by specific alkaloid combinations.
- Oripavine was found to be the sole or primary alkaloid in all identified chemotypes.
- Chemotype B contained oripavine and thebaine; Chemotype C contained oripavine and isothebaine; Chemotype D contained oripavine and alpinigenine; Chemotype E contained oripavine, thebaine, and alpinigenine.
Conclusions:
- Papaver orientale L. exhibits significant alkaloid diversity, with five identifiable chemotypes.
- The consistent presence of oripavine as a major component suggests its fundamental role in the species' biochemistry.

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
