The term "Umbelliferae" refers to a family of flowering plants, also known as the Apiaceae family. This family is characterized by plants that typically have hollow stems and produce flowers in the form of umbels, which are umbrella-shaped clusters. Common examples of plants in this family include carrots, parsley, dill, fennel, and coriander.

For more detailed information, please refer to the "Textbook of Pharmacognosy," which describes this botanical family, its characteristics, and its pharmacological importance.

Sorry, I cannot provide the content page as it's copyright material, but I can provide a summary or share information within the scope of the book related to your request. Crude drugs and advanced crude drugs are definitely concepts discussed in pharmacognosy, so here's what pertains to the book:

1. **Crude Drug**: In pharmacognosy, it refers to the unprocessed drugs obtained from natural sources such as plants, animals, or minerals. Examples include raw plant leaves, roots, or bark that are collected for their medicinal value before undergoing any purification or processing.

2. **Advanced Crude Drug**: Advanced crude drugs have undergone some level of processing or refinement to enhance their medicinal properties or make them suitable for pharmaceutical preparations. This includes fractionation, extraction, or isolation of specific active components.

Lipids and resins are both categories of organic compounds that are significant in the study of pharmacognosy, particularly in relation to medicinal plants and natural products. Here is a general explanation based on "Textbook of Pharmacognosy":

**1. Lipids**
Lipids are a diverse group of naturally occurring organic compounds that are soluble in nonpolar solvents (like fats, oils, and waxes) but insoluble in water. They are typically composed of long hydrocarbon chains or rings. In pharmacognosy, lipids are important as they serve various biological functions, such as energy storage, structural components of cell membranes, and chemical messengers. Types of lipids include:
- **Simple lipids:** Fats and oils (triglycerides) derived from fatty acids and glycerol.
- **Complex lipids:** Phospholipids, glycolipids, etc.
- **Derived lipids:** Steroids, terpenoids (e.g., cholesterol).

Lipids are also the basis of several medicinal plant products and are used in pharmaceuticals for formulations like ointments or creams.

**2. Resins**
Resins are complex mixtures of organic compounds, primarily terpenoids, that are secreted by plants as a protective mechanism. They are typically viscous or solid substances that are insoluble in water but soluble in alcohol or other organic solvents. Resins are formed as secondary metabolites in many plants, especially conifers, and are often associated with essential oils. They are used in medicines for their antiseptic, anti-inflammatory, and antimicrobial properties, and include:
- **Oleoresins:** Mixtures of oils (essential oils) and resins.
- **Gum-resins:** Mixtures of gums and resins.
- **Resin acids:** Components of resin with acidic properties.

Pharmacological uses of resins include applications as stimulants, carminatives, or antimicrobial agents, and specific examples include substances like benzoin and myrrh.

Glycosides are naturally occurring organic compounds in which a sugar molecule (glycone) is chemically bound to a non-sugar molecule (aglycone or genin) through a glycosidic bond. They are widely distributed in the plant kingdom and are important secondary metabolites with various biological activities and medicinal properties.

In pharmacognosy, glycosides play a significant role because many of them serve as active constituents of medicinal plants. Depending on the type of aglycone and their effects, glycosides can be classified into several categories, such as cardiac glycosides, anthraquinone glycosides, saponin glycosides, cyanogenic glycosides, and others. Each type holds significance in traditional and modern medicine due to their therapeutic applications.

Glycosides are hydrolyzed in the presence of acids, alkali, or specific enzymes to yield their sugar and aglycone components. The pharmacological activity of a glycoside is often attributed to its aglycone portion.

Alkaloids are naturally occurring organic compounds that primarily contain nitrogen atoms. They are produced mostly by plants, although some are synthesized by fungi, bacteria, and animals. Chemically, they are basic (alkaline) substances, hence the name "alkaloids." They are often characterized by complex structures and have diverse physiological effects on humans and other organisms.

These compounds are widely studied in the field of pharmacognosy due to their significant pharmacological activities, which include analgesic, antibacterial, anticancer, and psychoactive properties. Examples of alkaloids include morphine, quinine, nicotine, and atropine.

For details on the biosynthesis, classification, and pharmacological activities of alkaloids, you would need to consult the relevant chapter in *Textbook of Pharmacognosy*.
